Is there intelligent extraterrestrial life? Catholic thinkers give their opinion
If rational extraterrestrial beings exist, what would be God's relationship with them? The thought was previously purely speculative, but it could take on new meaning with the release of U.S. Department of Defense data on alleged encounters with “unidentified anomalous phenomena” or UAP.

UAPs - formerly known as ‘unidentified flying objects’ or UFOs - and the intelligence behind their existence have long been a source of public fascination, even before the discovery of UFO debris at Roswell, New Mexico, was claimed.
But Catholic theologians and scientists have also reflected on its implications for the way humanity perceives itself in relation to its Creator.
Among scholars researching this topic, the general consensus seems to be that the existence of extraterrestrial intelligent beings does not upset the Church's theology of creation.
Christopher Baglow, director of the Science and Religion Initiative at the McGrath Institute for Church Life at the University of Notre Dame in Indiana, addressed this question in a lecture given in 2021 for the Society of Catholic Scientists Annual Conference, a version of which he published in Church Life Journal.
His starting point was that humans and extraterrestrials share God as their creator, which gives extraterrestrials “the capacity for a special relationship with God in which they can know Him and respond to Him with freedom and love.”.
“God would love them and want to share his life with them,” he said.
St. John Paul II is said to have expressed a similar idea when a child asked him if extraterrestrials were real. “Always remember,” the late pontiff reportedly said. , “they are children of God, just as we are».
Although the Catholic Church does not offer a definitive teaching on extraterrestrial life, Catholic intellectuals have reflected on the subject over the centuries. In the 15th century, the German Cardinal Nicholas of Cusa, philosopher and theologian, speculated that God's creativity made the existence of intelligent life on other planets probable.
Much more recently, Jesuit astronomer Brother Guy Consolmagno posed a key question bluntly in the title of his 2014 book:“Would you baptize an alien?”.
Written in collaboration with Jesuit Father Paul Mueller, the book addresses various issues of faith and science through a question-and-answer format. As for the question that gives the book its title, it answers in the affirmative, but only if the alien requests it, since it is a sacrament that must be freely given and received.
Brother Consolmagno, a Detroit native, is president of the Vatican Observatory Foundation and served as director of the Vatican Observatory for a decade, from 2015 to 2025. “Any entity, no matter how many tentacles it has, has a soul,” he declared to The Guardian in 2010, adding that he would be “delighted” if intelligent extraterrestrial life were discovered.
The observatory's current director, Jesuit Father Richard D'Souza, shares a similar opinion.
“They would be children of God,” D'Souza said, referring to the extraterrestrial beings in 2025. “I believe in a benevolent Creator. He is behind everything.”.
Jesuit Father José Funes, another former director of the Vatican Observatory, leads the OTHER Project, which brings together scientists, theologians and philosophers at the Catholic University of Córdoba, Argentina, to study the possibility and potential impact of the existence of intelligent extraterrestrial beings.
“Just as there is a multiplicity of creatures on Earth, there can be other beings, even intelligent ones, created by God. And this does not contradict faith, because - and it is important to understand this - we cannot place limits on God's creative freedom,” he said in a article 2023 published by the Vatican Observatory.
“The existence of intelligent life on planets other than Earth is neither necessary nor excluded by any theological argument. Theologians, like the rest of humanity, must wait and see.”.
In a 2021 interview with Catholic News Service, Father Funes urged Catholics and others to consider the issue from an academic perspective, not from conspiracy theories.
Among the questions theologians-including the celebrated 20th century Jesuit theologian Father Karl Rahner-have asked is whether the Incarnation would have been repeated on other planets for other intelligent species. Both Father Funes and Dominican Father Thomas F. O'Meara, retired professor of theology at the University of Notre Dame and author of “The Incarnation of the Incarnate Word", and "The Incarnation of the Incarnate Word".“Vast Universe: Extraterrestrials and Christian Revelation”, they told CNS that the incarnation of Jesus was a “unique” event that would not necessarily take place beyond Earth.
This is a question that the Christian apologist C.S. Lewis, Anglican author best known for his “Chronicles of Narnia” series, explored through fiction in the late 1930s and 1940s with his “Space Trilogy”. The books - ”Out of the Silent Planet,” “Perelandra” and “That Hideous Force” - tackled the alien theme, popularized in the culture by other writers such as H. G. Wells, best known for “The War of the Worlds,” a novel first published in 1898 and infamous for its 1938 radio adaptation.
Lewis' work raises the possibility that rational beings from other planets may continue to live in a relationship with God that has not been affected by the fall and, therefore, do not need redemption in the same way that human beings do.
Lewis“ trilogy was also a focal point in a 31-minute documentary entitled "¿?What should Catholics believe about UFOs?”from Notre Dame's McGrath Institute. Produced by Brett Robinson of the same institute, the documentary brought together a number of scientists, theologians and other scholars to discuss the title question.
In the documentary, Lewis scholar Michael Ward points to Lewis“ own doubts about whether the current cosmological model could be overturned by new discoveries. Noting that Christian anthropology has accommodated other scientific advances, such as the Copernican system and Darwinian biology, Ward asserted, ”There is nothing new under the sun that cannot be integrated into the existing framework.".
Among the experts interviewed was Diana Walsh Pasulka, professor of religious studies at the University of North Carolina at Wilmington and author of. «American Cosmic, published in 2019 by Oxford University Press, which explores the phenomenon of belief in intelligent extraterrestrial life.
“A lot of people think that acknowledging the existence of non-human intelligences would change religion, eradicate it or discredit it altogether, but I don't believe that at all,” Pasulka said in the documentary. “Within the major religions there is wisdom on how to deal with non-human intelligence.”.
Pasulka, a practicing Catholic, sees a connection between contemporary reports of unidentified aerial phenomena and medieval descriptions of celestial phenomena, and her work has led her to correspond with aerospace engineers and members of the U.S. Space Force seeking explanations for their own experiences or research.
In an interview published in March in the Spanish newspaper ‘El Pais’, Pasulka said: “In the U.S. government right now there are many people who believe in UFOs, in unidentified aerial phenomena. That's a fact. They use taxpayer money to study it. But they have different interpretations.
“By the way, there is a high percentage of devout Catholics in the military who study this,” he added. “They believe that there are probably a variety of phenomena. Some would classify them as being caused by angels and demons. And then there are those they consider a threat, coming from an unknown extraterrestrial civilization. They just know they're here, and they treat them as a threat because they're military: if there's something in their airspace, they want to know what it is.”.
In March, Vice President J.D. Vance, a Catholic, called attention to the theory that aliens are fallen angels, saying in a podcast interview that. thought that the alleged extraterrestrials are demons, and that spiritual warfare is the easiest explanation for «alien phenomena».
Paul Thigpen, a theologian who passed away earlier this year, also explored that possibility in his 2022 book , Extraterrestrial Intelligence and the Catholic Faith: Are We Alone in the Universe with God and Angels?”. But he concluded that the spiritual realm was an unlikely explanation for all unidentified aerial phenomena (UAP). And he expressed concern that human contact with extraterrestrials could lead some to substitute their reality for that of God or to mistakenly regard them as a source of salvation.
“The Church could embrace this new scientific knowledge, just as it did with the scientific revolution of the 16th century that proved that the Earth is not the center of the solar system,” he said in an 2022 interview with the National Catholic Register.
“If we were to encounter directly an alien species, with the ability to communicate, the Church would, of course, have many questions about its spiritual and moral condition. The answers to those questions would determine the Church's response to such creatures.”.
“In examining the issues involved, we are forced to delve much deeper into the meaning of traditional Catholic teaching on the omnipotence and creativity of God, the image of God in humanity, the fall of the human race, the nature of the Incarnation, the means and scope of redemption, and the reality of the ‘end times.’”.
On May 5, Will Rahn of The Free Press published a podcast episode titled “Ehese two Catholics see signs of God in UFOs” featuring Pasulka and New York Times op-ed columnist Ross Douthat for a series titled “What Should Smart People Think About UFOs?”.
Douthat did not subscribe to any particular theory about the nature of extraterrestrial life, should it exist. However, he did acknowledge the tension Catholics might feel if it were proven to exist.
“Most Catholics are quite comfortable with a set of categories that are real but invisible,” Douthat said. “And it would be a change, say, if the Church were to say, ‘By the way, some of these supernatural beings can appear on Air Force cameras.’ That wouldn't be impossible, but it would involve a different way of thinking about these things than most Catholics currently have.”.

'Alien' message to the world uncovered in newly released UFO records
The FBI file contained never-before-seen memos and witness reports connected to UAPs

Rebekah JordanAn 'alien' message to the world has been uncovered in newly released UFO records.
The anticipation surrounding any official acknowledgement of extraterrestrial life has been building for years. President Donald Trump promised to address the question of alien life when the 'time is right,' yet one US congressman claims that contact has already been made.
Meanwhile, Stephen Hawking's theory has surfaced on social media that if intelligent life does exist out there, humanity might be better off hoping it never finds us. In other words, things sometimes stay hidden for a reason.
Now, the Trump administration's latest UFO disclosure release has revealed something pretty chilling.
The release was published on Friday and included never-before-seen memos, witness reports, photographs and videos connected to unidentified aerial phenomena (UAPs).
Among them was a memo dated January 12, 1955, originating from the Detroit Flying Saucer Club, one of the earliest UFO organisations in the US.
Club member Randall Cox told FBI agents that the group had been in contact with 'outer space people', and that those beings had delivered a series of warnings about humanity's place in the universe, the document read.
According to the FBI memo, the beings stated that all planets had conquered outer space except Earth and that humans were the ‘lowest form of universal existence.’
A further message stated that the purpose of contact with Earth at that time was simply to prepare people for future landings from outer space.
On a more reassuring note, the saucers were described as ‘friendly to the US’ with no potential threat of harm.
Among the documents was an interview conducted with Cox inside an FBI vehicle on January 11, 1955, during which he told agents he and fellow club member John Hoffman planned to travel to Washington, D.C. to present their information to the Pentagon.
Cox also referenced John Fry, a technician at Sandia Air Force Base in New Mexico, who allegedly claimed to have piloted a flying saucer from the base to New York City in just 30 minutes.
Hoffman, a former Air Force serviceman who served during the Second World War, was described in the memo as someone who had been 'carried beyond the realm of scientific fact into that of possible scientific fiction.'
The FBI also noted that Cox's accounts bore a striking resemblance to Dorothy Martin's notes. The Illinois housewife became nationally known in 1954 after claiming to receive telepathic messages from extraterrestrials she called the Guardians.
Martin led a small UFO group that warned catastrophic floods would destroy much of Earth on December 21, 1954, with believers to be rescued by flying saucers before the disaster struck.
When the apocalypse failed to materialise, Martin told her followers that a new message had arrived, explaining that Earth had been spared because of their collective faith.

Breaking the Silence: UFO Disclosure and its Global Impact
INDEX:
The Dawn of a New Era
The world is on the brink of a new era as governments and institutions begin to break the silence surrounding UFOs.
With the recent declassification of military files and a surge in credible sightings, the public’s fascination with the unexplained has reached an all-time high.
In this article, we will explore the implications of UFO disclosure and its global impact on society, politics, and scientific research.
For decades, the existence of unidentified flying objects (UFOs) has been shrouded in secrecy.
Government agencies around the world have maintained a tight grip on information relating to UFO encounters, leading to widespread skepticism and dismissal of the phenomenon.
However, recent events have thrust the topic into the mainstream, forcing authorities to confront the mounting evidence for extraterrestrial life.
The release of previously classified UFO files by various military and intelligence agencies has marked a significant shift in the global conversation surrounding UFOs.
These disclosures provide compelling evidence of unexplained aerial phenomena, captured by highly trained military personnel and advanced tracking systems.
As the veil of secrecy is lifted, we must consider the far-reaching implications of these revelations.

The global impact of UFO disclosure extends beyond societal and scientific realms, reaching into the sphere of international politics.
The shared recognition of UFOs as a legitimate phenomenon could foster unprecedented cooperation between nations, as governments work together to understand and address the implications of these encounters.
This newfound unity has the potential to reshape the geopolitical landscape, fostering an era of collaboration and diplomacy.
The media has a critical role to play in the dissemination of accurate, unbiased information regarding UFOs.
As the public’s appetite for knowledge about extraterrestrial life grows, journalists and news organizations must prioritize fact-checking and responsible reporting.
This will help to counter the spread of misinformation and ensure that public discourse remains grounded in truth and reason.
As we continue to grapple with the implications of UFO disclosure, it is essential that we approach this new reality with an open mind and a commitment to understanding.
By fostering a spirit of curiosity and collaboration, we can work together to unlock the secrets of the universe and build a better future for all of humanity.
The global impact of UFO disclosure has the potential to be transformative, touching every aspect of human existence.
From societal and cultural shifts to scientific advancements and political cooperation, the ramifications of this revelation will be felt for generations to come.
By embracing the unknown, we can embark on a journey of discovery that will forever change our understanding of the universe and our place within it.
As the reality of UFOs becomes more widely accepted, there will likely be economic implications that reverberate across industries.
The aerospace and defense sectors, in particular, could experience significant growth as governments invest in research and development to better understand and potentially replicate the advanced technology observed in these unexplained phenomena.
Additionally, the entertainment, tourism, and education industries may also see an influx of interest and revenue, as the public’s fascination with extraterrestrial life continues to grow.
The disclosure of UFOs raises essential ethical questions regarding our relationship with potential extraterrestrial lifeforms.
As we explore the cosmos and search for signs of intelligent life, we must consider the responsibility that comes with such a discovery.
This includes respecting the autonomy of other civilizations, preventing the spread of Earth-based contaminants to other planets, and ensuring that our actions do not inadvertently harm extraterrestrial life or ecosystems.
The global nature of UFO sightings and encounters highlights the need for international collaboration in the study and understanding of these phenomena.
By pooling resources, expertise, and data, nations can work together to form a more complete picture of the UFO phenomenon and its implications for humanity.
Such cooperation could also pave the way for future joint space exploration efforts and the establishment of international protocols for contact with extraterrestrial life.
The widespread acceptance of UFOs as a legitimate phenomenon will likely have psychological repercussions for individuals and society as a whole.
For some, the confirmation of extraterrestrial life may lead to feelings of awe and wonder, while others may experience anxiety or fear.
It is crucial for mental health professionals and researchers to explore the psychological implications of UFO disclosure and develop strategies to help individuals cope with the emotional challenges that may arise.
As our understanding of UFOs and the potential for extraterrestrial life evolves, the importance of incorporating this knowledge into educational curricula cannot be overstated.
By fostering a spirit of curiosity and critical thinking in students, educators can prepare future generations for the challenges and opportunities that come with exploring the cosmos and engaging with extraterrestrial life.

How a 4,000-year-old city defied history's 'rules' by becoming more equal as it became more successful
For decades, historians have generally agreed that the progress of small villages as they evolved into cities came at the price of widening inequality. A small group of leaders, kings and priests, would inevitably seize control of the wealth and the gap between rich and poor would grow.
But a new study at the University of York delves into the archaeology of the 4,000-year-old Mohenjo-daro, the Indus civilization's largest city, and shows the opposite was true. By analyzing house sizes across the ancient city, researchers found that Mohenjo-daro was not only more equal than its neighbors in Mesopotamia and Greece, but it actually became more egalitarian over time.
The lead author, Dr. Adam Green from the University of York's Department of Archaeology and Department of Environment and Geography, said, "Legacy data from the ancient city shows that as the city matured, the gap between the largest and smallest homes narrowed. In fact, by its later years, the wealth gap in this massive urban center had dropped to levels typical of the first farming villages.
"While ancient Egyptians were building pyramids for god-kings, and the Greeks were constructing massive palaces at Knossos, the people of the Indus were building something entirely different.
"Instead of gold-filled tombs and huge temples, Mohenjo-daro focused on sophisticated brick-lined drains and organized street layouts. Instead of allowing the perks of society to accumulate with a tiny elite, the city's amenities were widely distributed among the everyday households."
This was particularly true with regard to the distribution of the famous Indus seals, which were tools of business and trade. Indus seals were typically found in ordinary homes and not in public buildings, with no palaces to monopolize these tools of government.
It was evident that rather than a single ruler hoarding resources, the city's inhabitants worked together to ensure fair access to a good standard of life.
Investment in very practical things, like drainage and street maintenance, was also a sign of working collectively for the public good. The use of a standardized system of weights and measures across the region ensured that exchange remained fair for all citizens.
The findings, published in the journal Antiquity, challenge the modern assumption that rising inequality is an unavoidable side effect of economic growth. Mohenjo-daro, the researchers say, stands as proof that a society can be technologically advanced and highly productive while also ensuring its prosperity is shared by the many, rather than the few.
Dr. Green said, "Mohenjo-daro is often cited as being famous for what it doesn't have, such as the absence of palaces for kings, gold-filled tombs, and no statues of rulers. But what it does have is so important.
"In the period when inequality appears to be lowest, productivity appears to rise. It challenges the idea that prosperity requires us to concentrate decision-making powers in the hands of the few.
"It is quite an interesting lesson for modern societies, as the Indus civilization demonstrates clearly that an urban society can be highly productive and inventive at scale, while also ensuring that resources and power are shared equitably. In fact, doing so may even have been essential to sustaining prosperity over the centuries."
Earth’s oceans ruled by aliens? Former US Admiral’s explosive claims sparks UFO debate
'We are being visited and surveillance by a higher order of intelligence,' Tim Gallaudet says
In a recent interview with Popular Mechanics, Tim Gallaudet recounted an experience when he saw a UFO sighting in 2015 from a Navy F/A‑18 aircraft on the US east coast, the incident is called a “Go Fast” sighting.
The video showed a fast-going object appearing little more than a white dash on the aircraft screen.
According to Gallaudet, the object was something different because the speed at which it was moving went against the laws of Physics.
“So far, we have not built anything that can go that fast in the water and does not change speed from water to air. Many have had super-fast acceleration and made right-angle turns. We have not yet been able to engineer vehicles that can do that,” Gallaudet explained.
Gallaudet also convinced that these crafts are impossible to be operated by humans. These are only controlled by high-order intelligence and do not belong to a natural world.
“They may come from Earth, but I don’t believe they belong to the plant and animal kingdoms as we know them,” Gallaudet told Popular Mechanics.
This is not the first time, Ex-US Navy Admiral has dropped such explosive claims. Earlier this month, ex-Oceanographer of the Navy with 32 years of service, issued a stark warning, stating, “We are being visited and surveillance by a higher order of intelligence, one we do not understand and whose intentions remain completely unknown.”
“It’s happening very frequently, in our airspace and in our waters,” he added.
He also linked unidentified submersible objects to aerial sightings and has testified before Congress in 2024 and 2026 for greater transparency on military sensor data.
Ex-CIA expert claims there are 4 types of aliens recovered from UFOs including Reptilians
BY Andréa Oldereide - Senior Reporter
These are the alleged four alien species
A former CIA boffin has claimed that US agents investigating recovered UFO craft have identified four different types of alien species. In a new episode of the Diary of a CEO podcast, Dr. Hal Puthoff, a former CIA-funded researcher and Pentagon’s Advanced Aerospace Weapon System Applications Program (AAWSAP) advisor said he had been told by “high-level sources” involved in such programmes that there are “at least four” distinct alien species linked to recovered craft.
When talking on the 'Diary of a CEO' podcast alongside Age of Disclosure director Dan Farrah, the former CIA researcher was asked for details on what aliens had been found.
“Four separate types,” he said.
Representation of a Grey, a Nordic, a Reptilian, and an Insectoids
He added: “Now I have not had direct access to that, but I believe the people I talked to, four separate types of life at least.” The “four types” described have been attributed publicly to Dr Davis, a longtime collaborator of Puthoff, Brobible reported.
At a 2025 UAP Disclosure Fund conference, Davis reportedly categorised the alleged beings as “Grays”; small, hairless figures with large eyes, “Nordics”; said to be human-sized and resembling Northern Europeans, “Insectoids”; described as tall, mantis-like humanoids, and “Reptilians”; portrayed as humanoid figures with scaly skin and tails.
Puthoff also claimed there has been a longstanding culture of secrecy around the subject.

This reportedly includes what he characterised as a CIA strategy of spreading disinformation designed to deter serious public interest in UFOs.
Separately, Davis has for several years asserted that he has examined “off-world” wreckage and biological material from craft he says “we couldn’t make ourselves”.
On the podcast, Dr. Puthoff also alleged there had been a “CIA meeting where people got together and said, ‘Okay, in order to not have people be pursuing this area, let’s go out of our way to spread what we would call now disinformation.'”
Chaos
The alien claims remain anecdotal and unverified in public. Neither Dr. Puthoff or Davis have produced physical evidence, such as photographs, independently testable materials, or biological samples, to support the specific classifications being discussed.
Furthermore, Puthoff’s comments were explicitly presented as secondhand information based on conversations rather than direct access.
The UFO files: What did we learn from the Pentagon's 1st big release?

Earlier this month, the U.S. Department of Defense released what it termed "new, never-before-seen files" on unidentified anomalous phenomena (UAP), tagging it as a historic effort in transparency.
The UAP release came courtesy of the Trump administration's Presidential Unsealing and Reporting System for UAP Encounters, or PURSUE for short.
The posting involves 158 files — documents, photos and videos from NASA, the FBI, Defense Department, and State Department. Additional files are forthcoming, to be issued by the Department of Defense (DoD) "on a rolling basis." In a press statement, DoD Secretary Pete Hegseth remarked that his department is in lockstep with President Trump to bring unparalleled transparency regarding the government's understanding of UAP.

These Apollo 'UFO' images have been public for decades. So why are people talking about them now?
"These files, hidden behind classifications, have long fueled justified speculation — and it's time the American people see it for themselves," Hegseth said.
But just what are we seeing here? Space.com reached out to specialists to unravel what's behind sightings of UAP — or, as they used to be known, unidentified flying objects (UFOs).
For some, there is a "so what" — maybe a ho-hum — reaction to the UAP data release. Those familiar with UFO records, documents, or even astronaut sightings note that almost all of the "never-before-seen" files have long been known.
"I would view this first tranche as a useful beginning in what I hope becomes regular releases of documents not previously available, well documented sighting investigations and videos that aren't stripped of all necessary information," said Mark Rodeghier, president and scientific director of the J. Allen Hynek Center for UFO Studies.
Many of the FBI and other government files were already available, Rodeghier said, but fewer redactions and centralized access are still valuable.
"They allow researchers to check details more carefully and better reconstruct how official agencies received, evaluated and sometimes simply filed away UFO reports," Rodeghier added.
"Short videos and unresolved case summaries can be intriguing, but without the supporting metadata, investigative history and analysis, they are hard to evaluate," he said. "The real test will be whether future tranches provide complete case files, not just provocative fragments. True transparency means context, not just clips."
What to read next
Disclosure day: If ET made contact, how would we handle the news?
Similar in view is Robert Powell, an executive board member of the Scientific Coalition for UAP Studies.
"Recent government UAP disclosures have been valuable. They have confirmed that the public and the media regard this phenomenon as a matter of genuine importance," Powell said.
"But redacted files and the absence of credible scientific evaluation are not answers. They are a mandate," said Powell. "Academia and the scientific community can no longer afford to leave this field to institutions that operate in secrecy. The science of UAP must be conducted in the open, by those whose obligation is to the scientific evidence," he said.
Also taking on "does it matter and who cares" is Alejandro Rojas, a consultant for Enigma Labs, a group appraising UAP via the use of cutting-edge technology and social intelligence.
"The UAP transparency movement didn't start with this administration," said Rojas. "It's been building in Congress for several years, driven by bipartisan oversight and persistent public pressure. What we're seeing now is the continuation of that effort, not the origin of it," he said.
As for the recent DoD release, "it feels somewhat unfinished," Rojas said. "There are many cases with minimal context, missing sensor data, and little accompanying analysis, as if the priority was getting something out the door rather than something useful."
But imperfect data released publicly, Rojas added, is still more valuable than perfect data sitting in a vault. "Even a messy dataset reveals patterns over time, and every case added to the public record is one more data point researchers and citizens can work with. The question is what comes next, because this release raises more questions than it answers," he said.
On the lack of context and data, Rojas said that, for any meaningful scientific analysis, you need more than a grainy infrared clip and a one-paragraph summary.
"These reports are largely missing the basics — coordinates, sensor parameters, altitude, speed confirmation. Many cases appear to have been flagged as UAP simply because there wasn't enough data to identify them, rather than because they exhibited genuinely anomalous behavior," said Rojas.
"That's not a criticism of the release," he added, "it's just the reality of what we're working with. Real analysis requires real data, and hopefully future releases include more of it."
Enigma Labs has built a website offering anyone — researchers, journalists, curious members of the public — the opportunity to search and explore these files as they come out, rather than hunting through a government portal.
"We're also collecting public sighting reports and giving people a community to discuss and analyze what's being released," Rojas added. "The goal is to make this process as open and accessible as possible, because transparency only works if people can actually find and use the information."
For the first time in history, the White House and a number of government agencies "have acknowledged that there is a real and inexplicable phenomena occurring on a global basis that demands attention," said Michael Gold, president of Redwire Space, a space and defense company focused on advanced technologies.
Gold has experience delving into uncanny oddness in the skies. He served on NASA's UAP Independent Study Team that ran from 2022 to 2023. He said he's particularly grateful that the DoD (which the Trump administration has unofficially rebranded the Department of War) and NASA acknowledged that the object in the Apollo 17 imagery was real and unknown.
"The most powerful words in science are 'I don't know,' and I appreciate NASA and the Department of War being modest enough to acknowledge when a good explanation doesn't currently exist," said Gold. "Acknowledging anomalies is the first step to discovery, and is how scientific progress is made."
Gold emphasized that it's important to acknowledge the unprecedented nature of the White House's treatment of UAP. "I would like to compare the White House release to similar actions by prior administrations, but I can't, since there are none," he said.
The Trump administration and the agencies involved, Gold said, "should be applauded for supporting transparency despite what I'm certain were incredible and historic challenges to not just releasing information, but even just treating the UAP issue with the seriousness that it deserves."
In his 2024 testimony before Congress, Gold urged NASA to conduct a review of its archives for UAP.
"Another recommendation I made to Congress and supported by the NASA UAP Independent Study Team was for UAP to be added to NASA's Aviation Safety Reporting System [ASRS]," said Gold.
ASRS provides the U.S. Federal Aviation Administration with confidential data relative to safety anomalies. ASRS has provided the federal government with hundreds of thousands of confidential reports and has successfully operated for years, Gold said.
If UAP were added to the anomalies that ASRS collects, Gold said, every commercial pilot, crew member, and even passengers could act as sensors for UAP, providing a treasure trove of data.
"I hope that more files will be released soon that will show even more definitively anomalous behavior," Gold concluded. "I expect we are at the beginning, not an ending, of a very important moment in the history of science."

Earth's sinking cities: Study reveals the urban areas plummeting toward sea level – leaving millions of residents at risk of being plunged underwater
Rising sea levels are already putting millions at risk of flooding – but a study now warns that land subsidence is making the danger even greater.
Earth's sinking cities are slipping towards sea level at an alarming rate, experts from the Technical University of Munich have warned.
A study showed that subsidence more than doubles the rate of sea level rise for some areas of the coastline.
To make matters worse, researchers say that this affects the largest and most densely populated cities more than anywhere else.
Between rising seas and sinking land, heavily urbanised areas of coast experience a relative sea level increase of about 6mm per year on average.
That is three times more than the global average for relative sea level rise, which stands at 2.1mm per year.
Likewise, land subsidence roughly doubles the absolute sea–level rise of 3.15mm per year, which measures the actual increase in volume and height of the ocean.
Lead researcher Dr Julius Oelsmann, of Technical University of Munich, says that this can 'significantly amplify the effects of climate–driven sea–level rise'.
Scientists have found that land subsidence is doubling the rate at which the water level rises in some of the world's biggest cities, putting millions at risk of flooding. Pictured: Rate of uplift (red) and subsidence (blue) in coastal areas
Jakarta is the world's fastest–sinking city, subsiding at a rate of 13.7mm per year. This puts the megacity's 42 million residents in extreme danger of flooding. Pictured: Flooding in Jakarta following heavy rain in 2024
As the climate gets hotter, melting glaciers and the expansion of warming water are gradually raising the level of the world's oceans.
However, Dr Oelsmann and his co–authors warn that the surface of the sea only tells half the story.
'If we want to understand sea–level rise along coastlines and respond effectively, we must not only observe the ocean but also the land itself,' Dr Oelsmann says.
This is because a mixture of human activity and natural forces is combining to sink some of the world's biggest cities into the ocean.
The biggest factors driving this subsidence are excessive groundwater and oil extraction, which remove underground resources that previously stabilised the surface.
Dr Oelsmann points out that the 'sheer weight of cities' is also driving urban areas below sea level.
As cities grow larger and taller, heavier buildings are constructed, which compacts the ground beneath and slowly sinks the city relative to its surroundings.
Combined with climate–change–driven sea level increase, urban areas are seeing the waterline rise a lot faster than the rest of the world.
In the UK, the US, and Europe, areas of the coastline are sinking into the sea due to land subsidence. This is leading to a significantly faster rate of relative sea level increase
Countries where relative sea levels are rising the fastest include Thailand, Bangladesh, Nigeria, Egypt, China, and Indonesia, where the ocean is getting seven to 10 millimetres higher each year.
The US, the Netherlands, and Italy also experience exceptionally rapid increases, with relative sea levels rising by around four to 5mm per year.
Due to the strong influence of city size, many countries also featured intense 'hot spots' of subsidence.
The 42 million residents of Jakarta, Indonesia, the world's most populous city, are in particular peril as the megacity slips towards the ocean at a rate of 13.7mm per year.
This is closely followed by Tianjin, China, home to 13.8 million people, which is seeing 13.5mm of subsidence per year.
Similarly, Bangkok, Lagos, and Alexandria are all experiencing well above average rates of subsidence with 8.5, 6.7, and 4mm per year, respectively.
Even within cities, the different rates of subsidence meant that one neighbourhood might be falling towards the ocean while others rise out of it.
In Jakarta, for example, some parts of the city are sinking at a staggering 42mm per year, while other regions actually see uplift.
Densely populated urban coastal regions are experiencing around 6mm of relative sea level increase per year (red regions)
This means that millions of people in some of the world's biggest cities are being put at risk of severe flooding.
Even if their homes don't fall completely below sea level, every millimetre of relative sea level increase creates a bigger risk that storms or extreme weather will lead to severe floods.
This is especially concerning for Jakarta, where about 40 per cent of the city is below sea level.
Studies estimate that nearly half of the city could be inundated and uninhabitable by 2050 if sea levels continue to rise at the current rate.
These dense, urban regions stand in stark contrast to Scandinavia, where natural geological processes are gradually lifting the land out of the sea.
During the last Ice Age, these northern latitudes were weighed down with vast ice sheets that pushed the land into the ocean, much like coast megacities do today.
As these ice sheets have retreated, that weight was removed, and the land masses are still 'rebounding' towards a stable position.
That means, even as absolute sea levels increase, the relative sea level in Finland and Sweden is actually getting lower each year.
Unfortunately for the rest of the world, there are no geological processes to pull cities back out of the water.
However, the researchers point out that proper city planning can dramatically slow the rate of subsidence.
Co–author Professor Florian Seitz, of the Technical University of Munich, says: 'In many large coastal cities, groundwater extraction is a major driver of land subsidence.
'This means that local political and water–management decisions can make a significant difference.'
In Tokyo, Japan, for example, subsidence rates once exceeded 10cm per year, reaching peaks of 24cm per year in the worst areas.
However, through government intervention and the introduction of new water sources, those rates were dramatically reduced.
'Improved groundwater management, stricter regulation of withdrawals, or targeted recharge of aquifers can at least slow subsidence rates and, in some cases, largely halt them,' says Professor Seitz.

Scientists have managed to hatch live chicks from a fully artificial egg – marking a de–extinction breakthrough that paves the way for resurrecting long–dead species.
Experts at Colossal Biosciences, the company planning to bring back the woolly mammoth, have created the first ever shell–less incubation system that mirrors a natural egg 'as much as possible'.
The team were able to take early bird embryos, place them into an artificial shell and incubate them for 18 days while they developed.
Once the chicks were ready, they hatched from their cosy home and are now living happy, healthy lives.
The company said the development marks a critical milestone for their plans to de–extinct the South Island giant moa – an enormous bird that stood at 11.8ft (3.6 metres) tall and weighed 507lbs (230kg).
It also provides a 'stepping stone' for the eventual development of an artificial womb.
Colossal Biosciences said: 'This device changes everything. We're showing the world that we can grow this whole bird in an incubator outside of an eggshell.
'It's a complete game–changer. Life finds a way.'
Experts have created the first ever shell–less incubation system that mirrors a natural egg 'as much as possible'
The artificial egg features a 'window' on the top, allowing for real–time visibility into every stage of embryonic development
The artificial egg device consists of a 3D–printed strong outer shell structured like a lattice to provide protection and rigidity.
Within this layer is a silicone–based membrane that allows oxygen to diffuse into the system.
Over the last 40 years there have been several attempts to create artificial eggs, but they required supplementation with large volumes of pure oxygen which caused DNA damage and impacted long–term animal health.
The permeable membrane of this new design allows oxygen to naturally transfer from the atmosphere into the egg.
This mirrors the real–life process of oxygen entering eggshells through microscopic pores.
'How do we replicate nature but also improve upon it?' Colossal said. 'This is the first time the core engineering problem of artificial eggs has been solved.'
The artificial egg also features a 'window' on the top, allowing for real–time visibility into every stage of embryonic development.
Colossal said its device is compatible with standard commercial incubators, is manufacturable at scale and is adaptable to eggs at any size.

Once the chicks were ready, they hatched from their cosy home and are now living happy, healthy lives
To begin the process, experts collected real chicken eggs right after they had been laid.
An embryology team thoroughly examined each egg and selected the embryos that looked most likely to hatch.
They then cracked the egg open very gently and transferred the contents into the artificial egg, which was then placed in an incubator.
Scientists 'sprinkled' in a nutrient that helped the embryo continue to develop. Roughly 18 days later the chick started tapping against the egg to indicate it was ready to hatch.
After hatching, all chicks were put in groups and eventually moved to a 'graduation pen' outside before being relocated to a large farm.
Colossal said its design could also benefit endangered animals at a time when more than half of bird species are in decline.
'Imagine a future where we have hundreds or thousands of eggs in laboratories growing critically endangered species,' it said.
'These are the stepping stones that an artificial womb will be built on.'

Colossal said its device is compatible with standard commercial incubators, is manufacturable at scale and is adaptable to eggs at any size
The company said its plan to bring back the South Island giant moa has presented an incubation challenge unlike any other species in their portfolio.
Moa eggs are estimated to have been approximately 80 times the volume of a chicken egg and roughly eight times the volume of an emu egg, placing them entirely beyond the capacity of any available avian surrogate.
No living bird is large enough to serve as a host. A size–scaled artificial egg, therefore, is critical for the de–extinction of this species.
Colossal Biosciences will use genes extracted from moa bones to engineer modern birds until they very closely resemble the extinct species, which disappeared from New Zealand roughly 500 to 600 years ago.
This is the same technique that was used to transform grey wolves into animals closely resembling dire wolves.
The edited embryos will then be placed into an artificial egg to develop and eventually hatch.
'We've created a novel shell–less culture system that is fully scalable and biologically accurate,' said Professor Andrew Pask, chief biology officer at Colossal. 'It's a new system designed for long–term, healthy avian embryo development.
'The genome is the blueprint, but without a place to build, it's meaningless. The artificial egg gives us that platform: controlled, scalable, and completely independent of a surrogate.'
The company said the development marks a critical milestone for their plans to de–extinct New Zealand's South Island giant moa – an enormous bird that stood at 3.6 metres (11.8ft) tall and weighed 230kg (507lbs)
The moa went extinct in the 15th century due to hunting and forest clearing by the first Māori settlers. Colossal Biosciences said restoring this megafauna species will help restore New Zealand's ecosystem
Some outside experts have cautioned that there is no published scientific paper along the announcement, which limits scientific scrutiny. However, others hailed the advance as an 'impressive act of bioengineering'.
Carles Lalueza–Fox, director of the Museum of Natural Sciences of Barcelona and a specialist in DNA recovery techniques, said: 'Colossal has succeeded in developing an artificial egg, something for which there are no comparable precedents.
'The most significant breakthrough lies in the permeability of the membrane, which allows gases (oxygen and carbon dioxide) to pass through.'
Alongside the moa, he said the device could be used to de–extinct other birds such as the Carolina parakeet.
Dusko Ilic, Professor of Stem Cell Sciences at King's College London, said: 'Recreating an extinct species such as the moa would require far more than an incubation platform, including accurate genome reconstruction, appropriate development, physiology, behaviour, welfare and ecological context.
'Even then, the result would likely be an engineered proxy rather than a true restoration of the extinct species.
'The most credible translational value may therefore lie in applications such as embryo rescue, endangered bird conservation and controlled generation of genome–edited avian lines, particularly if it proves reproducible, scalable and compatible with normal long–term health, rather than in de–extinction itself.'
Trump posts mysterious AI images featuring an Alien and Cosmic War
Fresh wave of UFO files to be released after Trump sparked chaos with alien picture
The second phase of the Trump Administration's UFO disclosure is underway, with officials saying the next batch of files is expected to be released 'very soon.'
Chief Pentagon spokesperson Sean Parnell announced Monday on X that the materials are currently 'actively being processed' for publication.
The first release, published on May 8, included never-before-seen photos, videos and government documents tied to unidentified anomalous phenomena, also known as UAPs.
Lawmakers previously noted that the initial disclosure was only the beginning, teasing that far more explosive material remained hidden from the public.
Tennessee Representative Tim Burchett, one of Congress’ most outspoken advocates for UFO transparency, fueled speculation after the May 8 release by claiming: 'The 1st drop will be big, but in comparison to what is coming, they will be a drop in the bucket.'
'I would say "Holy Crap" is coming,' Burchett added.
The latest update arrived just one day after President Donald Trump posted an AI-generated image of himself standing beside a handcuffed alien at a US military base, further intensifying online discussion surrounding the administration’s disclosure campaign.
The surreal image, shared on Trump’s Truth Social account, showed the president and his security detail escorting the extraterrestrial figure across the tarmac while armed military personnel looked on.

News of the second release flooded social media, where one user said: 'Finally! The government's processing UFOs faster than my laptop processes a software update.
'Either we're getting disclosure or the world's longest episode of coming soon. Either way, grab your tinfoil hat, things are getting interesting.'
Others, however, are not sold on the notion that the files will be released soon.
One X use posted: 'The phrase "actively being processed" is classic government doublespeak, suggesting momentum while committing to absolutely nothing, keeping the UFO hype alive without releasing a single page.
'It's the perfect way to acknowledge public curiosity without ever having to deliver, turning transparency into an endless process rather than an event.'

Burchett also made similar statements in a video posted on Monday, suggesting the files could be withheld.
'The problem we have right now is that the Deep State's fighting a president on release. And he kept his word,' he told Morell Media.
'I suspect some of our not-so-friendly comrades in some alphabet agencies are slow-walking a lot of information. It's about power, it's about control. That's kind of what runs Washington.'

The release of the first batch was teased the evening of May 7 by Florida Representative Anna Paulina Luna, who posted cryptic messages suggesting it would happen the next day at 8am ET.
The documents were made public months after the President ordered the Secretary of War, Pete Hegseth, to declassify government records related to UFOs and alleged extraterrestrial activity.
Among the most striking materials were images and transcripts linked to NASA's Apollo 12 and Apollo 17 missions. One photo taken from the lunar surface appears to show three unexplained dots hovering in the dark sky above the moon.
The disclosure also included FBI images from New Year's Eve 1999 that appear to show unidentified objects near US military aircraft, along with photographs captured by military pilots allegedly showing fast-moving objects streaking past planes mid-flight.
A bizarre glowing object resembling an 'eight-pointed star' streaking across the sky was among the most chilling videos released in Friday's bombshell UFO disclosure.
The eerie infrared footage, captured by US military personnel in 2013, appears to show something darting through the darkness with uneven, shape-shifting arms.
Interest surrounding the disclosures intensified after Luna, chair of the House Oversight Task Force on Declassification, previously said dozens of military UFO videos remained hidden from the public.
One image released in the first batch appeared to show a bright circular object within a military targeting reticle, although officials said the description should not be interpreted as confirmation of the object's nature or significance
Luna had requested the release of 46 classified UAP videos earlier this year, including footage allegedly captured near military bases, war zones and restricted airspace.
The Pentagon missed an April deadline to release the materials, later attributing the delay to what officials described as a clerical issue.
Officials have not confirmed whether the second phase will include additional videos, radar data, pilot testimony or classified intelligence assessments.
Scientists are baffled by mysterious blue flashes coming from deep space that are 'unlike anything we have observed before'
For almost a decade, scientists have been baffled by a series of mysterious blue flashes emerging from deep space.
Since the first lit up astronomers' telescopes in 2018, only 14 of these strange pulses have been detected, making them some of the rarest astronomical events on record.
Known as Luminous Fast Blue Optical Transients (LFBOTs), these lights burn faster and up to 100 times brighter than anything else scientists have seen.
Now, a group of scientists think their origin lies in the unlikely collision between a black hole and an ultra–hot sun.
LFBOTs come and go astonishingly fast, reaching their dazzling peak and fading into oblivion over days compared to the weeks or months of most stellar explosions.
Strangely, they also maintain their unique blue glow over the entire course of their brief display, which suggests they must be extremely hot the whole time.
Lead author of a new paper investigating these flashes, Dr Anya Nugent, from Harvard & Smithsonian, says this makes them 'unlike anything we have observed before'.
However, Dr Nugent now believes that LFBOTs' origins are just as violent, unusual, and unlikely as their spectacular effects.
Scientists have been baffled by mysterious blue flashes emerging from distant galaxies for almost a decade. Now, researchers say they could be caused by black holes hitting bright stars. Pictured: A blue flash coming from AT 2024wpp, a galaxy 1.1 billion light–years from Earth
In their pre–print paper, Dr Nugent and her co–authors examine the kinds of galaxies that the few confirmed blue flashes have been seen in.
By measuring the rates of star formation, mass, and levels of metallic elements in these galaxies, the researchers paint a picture of how LFBOTs might form.
This data suggests that they could be caused by ultra–dense objects like black holes or neutron stars colliding with an exceptionally bright sun called a Wolf–Rayet star.
Wolf–Rayet stars begin their lives as one part of a binary star system, in which two stellar giants orbit around a central point.
As these stars creep closer together, the larger of the two starts to feast on its neighbour's outer layers.
If they are just the right size, the 'donor' star's outer hydrogen layer is stripped away without destroying it completely, leaving the bright helium core known as a Wolf–Rayet star.
At the same time, the cannibal grows so fat on hydrogen stolen from the donor that it collapses under its own enormous bulk.
The star collapses inwards and detonates in a supernova explosion that leaves behind a stellar remnant, in the form of a black hole or neutron star.
Known as Luminous Fast Blue Optical Transients (LFBOTs), these lights burn faster and up to 100 times brighter than anything else scientists have seen (artist's impression)
Scientists now say that LFBOTs may emerge from Wolf–Rayet stars, a massive class of stars that form when a black hole strips away the sun's outer hydrogen layer. Pictured: A Wolf–Rayet star 15,000 light–years from Earth that is 30 times the mass of the sun
That black hole continues to feed on its neighbour until, over hundreds of thousands of years, it falls into the stellar core and destroys it, triggering an LFBOT.
Co–author Professor Brian Metzger, of Columbia University, told the Daily Mail: 'When the compact object plunges into the Wolf–Rayet star, it can rapidly accrete the stellar [material] and release a huge amount of gravitational energy.
'Some of that energy drives powerful outflows or jets, which then collide with material around the star.
'That interaction can produce a very hot, bright flash of light on a short timescale.'
Wolf–Rayet stars are ideal candidates for producing LFBOTs for a few critical reasons.
First, the light from LFBOTs doesn't show the telltale signature of elemental hydrogen, which suggests they should come from stars that have lost their hydrogen layer.
Wolf–Rayet stars are also massive and dense, which allows the black hole to feed as fast as possible and produce a colossal burst of light.
Finally, Professor Metzger adds: 'They can also have dense material around them from earlier episodes of mass loss, which gives the explosion something to crash into and helps power the observed emission.'
When a black hole falls into its neighbouring Wolf–Rayet star, the destruction releases a massive burst of energy which briefly appears as LFBOT, such as this one spotted by NASA in 2023
Previously, scientists had thought that the bright surge of light could either come from an unusual type of supernova explosion or from a large star being torn apart by gravitational forces.
However, the LFBOTs that scientists have seen don't come from galaxies where either of these would be likely.
These galaxies either tend to have a rate of new star formation that is either too fast or too slow to fit with known types of supernovae.
Additionally, the black hole collision theory also helps to solve the biggest mystery surrounding these blue flashes.
LFBOTs are often found in the very outer reaches of their host galaxies, far away from the densely packed galactic centre.
For example, one flash was spotted breaking out from a region some 55,000 light–years away from its galaxy's core.
Another known as 'The Finch', found by NASA in 2023, was spotted on its own more than 50,000 light–years from the nearest spiral galaxy.
This is extremely unusual because, if they are being triggered by stars, you would expect to see them more often in regions where stars are the most tightly packed.
Scientists had thought that the bright surge of light could come from an unusual type of supernova explosion, but the galaxies where LFBOTs are found don't match those where these explosions are likely
Dr Nugent says: 'We think it's because their progenitors must have received a "kick" to push them out of their birthsite and away from these regions in their host galaxies.
'Stars can get strong kicks from supernova explosions, and if LFBOTs do indeed come from compact object–Wolf–Rayet star mergers, it is more than likely that the star that created the compact object underwent a supernova that gave the binary system the kick.'
The researchers admit that, since the number of LFBOTs is still so small, this is far from a 'closed case'.
Many more observations will be needed before scientists can be absolutely certain what is triggering these bizarre explosions.
However, they expect that the Vera C. Rubin Observatory and its newly started decade–long Legacy Survey of Space and Time should help provide those answers.
Huge asteroid with the potential to obliterate an entire city will skim past Earth TONIGHT – here's how you can watch the narrow miss live
An enormous asteroid with the potential to destroy an entire city will skim past Earth this evening.
Astronomers say the space rock, called 2026 JH2, is up to four times the size of a London bus and will get 'as close as you can without hitting'.
It is expected to zoom by our planet at an estimated distance of around 56,000 miles (90,000km) at 10:23pm BST.
This is exceptionally close – the equivalent of just a quarter of the distance between us and the moon.
Estimates place the size of the space rock between 52 and 115ft (16 and 35 metres) in diameter, and it is racing towards Earth at around 20,000mph (32,000 kmph).
Despite having enough mass to wipe out a city, simulations suggest there is no chance of impact for at least the next 100 years.
While it will be too faint to see with the naked eye, it may be visible through amateur telescopes under dark sky conditions. But for those without access to stargazing equipment, you can still watch the unusually close encounter.
Astronomers in Italy will be sharing a livestream of the flyby, recorded through a telescope, on The Virtual Telescope Project's YouTube channel. The broadcast will start at 8:45pm BST.
This illustration shows the orbit of asteroid 2026 JH2 (grey) relative to Earth's orbit (light blue). Its oval–shaped orbit takes it nearly as far out as Jupiter
Thankfully, simulations suggest there is no chance of an impact for at least the next 100 years (stock image)
People in the UK will have the best chance of spotting asteroid 2026 JH2 from dark–sky locations with a clear northern horizon.
Around closest approach, it should be moving through the region of Ursa Major, fairly high in the sky.
Binoculars probably won't be good enough unless they are very large. However, it should be visible with small telescopes.
It will look like a faint moving dot, rather than a dramatic streak.
The asteroid was first discovered on May 10 by astronomers at the Mount Lemmon Observatory near Tucson in Arizona.
Data suggests it likely circles the sun every 3.7 years on an oval–shaped orbit that takes it nearly as far out as Jupiter.
The size of the asteroid is an estimate based on the amount of light reflecting off its surface, which means that measurements cannot be entirely certain.
If the asteroid is made of a particularly dark or unreflective material, then it could be nearer to the higher end of the estimate range or potentially even larger.
2026 JH2 is expected to zoom by our planet at an estimated distance of around 56,000 miles (90,000km) tonight
Estimated to be between 16 and 35 metres (52 to 115ft) across, 2026 JH2 is a similar size to the 20–metre Chelyabinsk meteor (pictured), which exploded with 30 times the energy of the atomic bomb dropped on Hiroshima
However, even at the lower end of its estimated range, the asteroid still carries a huge destructive potential.
'It's the kind of thing that would ruin a city quite efficiently, if it hit,' Mark Norris, from the University of Lancashire, told New Scientist.
Experts say if 2026 JH2 did strike Earth, it would cause an event comparable to the Chelyabinsk meteor.
In 2013, an 18–metre (59ft) meteor exploded over the city of Chelyabinsk in Russia, near the border with Kazakhstan.
The resulting explosion was 30 times more powerful than the atomic bomb dropped on Hiroshima, producing a shockwave that travelled twice around the world.
Directly beneath the explosion, 28 miles (45km) above the ground, the heat was so intense that people were left with burns and retinal damage.
Around 1,500 people were injured and over 3,600 homes were damaged, even though only 0.05 per cent of the original rock made it to the ground.
With a potential size up to 35 metres (115ft) in diameter, 2026 JH2 has the potential to be even more destructive – possibly even ranking it as a 'city killer' size asteroid.
However, although the asteroid will pass extremely close to the planet, it poses no threat whatsoever to Earth.

The next sizable space rock that will get this close to Earth will likely be the 'God of Chaos' asteroid, 99942 Apophis, which will fly within 20,000 miles (32,000 km) of Earth on April 13, 2029.
After Apophis, the next major flyby will be from 2024 YR4, also known as the 'city killer' asteroid, which will zoom past the moon at a minimum distance of around 13,200 miles (21,200 km) in 2032.

Neil DeGrasse Tyson: If Any Of These“For Years We Couldn’t Understand It”: What’s the Massive Anomaly Lurking in the Clouds Over Venus?
A mysterious weather anomaly on Venus has finally been explained in new research, providing deeper insights into the weather volatility of other planets in our solar system.
University of Tokyo researchers revealed their findings in a recent paper published in the Journal of Geophysical Research, focused on their investigation of a massive cloud disturbance observed on the second planet from the Sun.
This unusual cloud phenomenon involves a 6,000-kilometer-wide wave front that travels around Venus over just a few Earth days, and scientists believe it could potentially affect future space missions.
Japan’s Akatsuki Venus orbiter first observed Venus’s enormous, 6,000-kilometer-wide atmospheric wave move across the planet’s equator at tremendous speed in 2016. Now, a decade later, the University of Tokyo team has some answers about this peculiar feature.
Compared to Earth, Venus is a slow mover, with its rotation even slower than its 243-day orbit. Despite this, Venusian clouds move at an incredible pace, 60 times the planet’s rotational speed in what is known as “superrotation,” a phenomenon also observed on Mars, the Sun, and Earth’s supersonic atmosphere.
“We identified the phenomena, but for years we couldn’t understand it,” said lead author Professor Takeshi Imamura from the Graduate School of Frontier Sciences at the University of Tokyo. “However, thanks to this research, we’re now able to show that this cloud disruption is caused by the largest known hydraulic jump in the solar system.”

The Venusian atmosphere is hot, dense, and toxic, being composed of almost 97% carbon dioxide. This results in constant cloud cover, which rains sulfuric acid. While this creates a deadly environment for humans, at a distance, it’s a perfect natural weather laboratory. This extreme cloud density makes hard-to-spot weather patterns and processes more readily apparent than they would be on a planet such as ours.
The strange formation in the Venusian atmosphere resulted from a sudden slowdown of the fluid, known as a hydraulic jump, produced when a large atmospheric Kelvin wave moving east across Venus becomes unstable in the lower to middle cloud region. The Kelvin wave’s sudden slowing produces an updraft, pushing sulfuric acid vapor into the upper atmosphere, where it can condense into clouds. As though clouds trail, they form the enormous wavefront spotted by Akatsuki Venus.
“Venus has three distinct cloud layers, and the dynamics of the lower and middle layers are not so well understood,” said Imamura. “Our discovery of a hydraulic jump on Venus connecting a very large-scale horizontal process with a strong localized vertical wave is unexpected, as in fluid dynamics these are usually disconnected.”
The Japanese researchers used a fluid-dynamic model to simulate the hydraulic jump observed on Venus, combined with a microphysical box model to track air flow through the atmosphere. In their analysis, the University of Tokyo researchers identified how the cloud disturbance maintains the Venusian atmosphere’s superrotation.
“Up until now, we used a global circulation model (GCM) for Venus that is similar to Earth’s, but this model doesn’t include the hydraulic jump which we have now identified,” explained Imamura. “Our next step will be to test this discovery within a more inclusive climate model that includes other atmospheric processes. We will face challenges due to the significant processing power required to run such simulations. Even with modern supercomputers, it isn’t easy.”
Mount Roraima: Evidence of Ancient Cutting Technology?
Rising abruptly from the lush, untamed jungles of southeastern Venezuela, Mount Roraima is a geological behemoth that defies logic. With its perfectly flat plateau and sheer, vertical cliffs plunging thousands of feet into the mists below, it looks less like a natural mountain and more like a colossal, ancient fortress. For decades, alternative researchers and mystery enthusiasts have looked at these impossibly straight geological lines and asked a controversial question: could Mount Roraima be the result of artificial cuts? This massive tepui, surrounded by a harsh and isolated landscape, continues to capture the imagination of explorers and scientists alike.
The sheer scale of Mount Roraima is breathtaking, with its summit covering roughly 31 square kilometers (12 square miles) and its highest point reaching 2,810 meters (9,219 ft). The walls of the tepui are so remarkably vertical and smooth that they appear to have been sheared off by advanced machinery. This visual anomaly has fueled endless speculation about ancient, highly advanced civilizations or even extraterrestrial architects who may have terraformed the region in the distant past. However, distinguishing between the myths of ancient builders and the harsh realities of geological time requires a deeper look into both the stone and the people who live in its shadow.
A traveler sitting on the rocky, alien terrain of Mount Roraima's plateau, looking out over the clouds and sheer cliffs.
To understand the intense speculation surrounding Mount Roraima, one must first look at its baffling geography. The mountain is part of the Pacaraima chain, a series of tepuis, table-top mountains that dominate the Gran Sabana region. When clouds roll in, obscuring the base of the mountain, Mount Roraima appears to float in the sky like a solid island of rock. It is this otherworldly appearance that inspired Sir Arthur Conan Doyle's famous 1912 novel, "The Lost World." The stark 90-degree angles of the cliff faces look distinctly non-natural, leading many to draw comparisons to ancient megalithic structures like Stonehenge or the perfectly cut stones of Puma Punku.
A dramatic view of a tepui's vertical stone walls rising out of the mist. Visually represents the "artificial cuts" debate.
Proponents of the artificial cuts theory point to the immense, block-like formations that litter the plateau and the base of the cliffs. Some of these gigantic stone blocks appear uniformly rectangular, resembling quarried masonry on a scale far beyond human capability. Could a lost civilization have used advanced technology to mine this mountain for precious minerals? While this theory is incredibly compelling and makes for fantastic lore, modern science offers a different, yet equally fascinating, explanation for these supposedly artificial features.
Geological studies have consistently shown that the secret to Mount Roraima lies in the immense power of deep time. According to a comprehensive 2019 study by Sauro et al., the tepuis are composed of ancient Precambrian quartz arenite sandstones. Over millions of years, a unique weathering process known as "arenization" slowly dissolved the quartz. This relentless chemical and physical weathering, combined with massive structural collapses, naturally creates the sheer vertical walls and the giant, block-like sinkholes that mimic artificial cuts. Nature, given enough time, is the ultimate master mason.
While modern science attributes the shape of Mount Roraima to the slow dissolution of quartz sandstone, the indigenous peoples of the region have their own profound explanations. For the Pemon and Kapon tribes, who have inhabited the Circum-Mount Roraima landscape for centuries, the tepui is deeply woven into their cultural DNA. They do not see the mountain as an artificially cut quarry, but rather as the sacred remnants of a cosmic event. Anthropological research, including recent ethnographies by Riris et al. (2025), details the rich oral traditions that view Mount Roraima as the stump of the mighty "Tree of Life."

According to local folklore, this colossal tree once bore all the fruits and vegetables of the world, providing endless sustenance for humanity. However, a legendary trickster figure named Makunaima chopped down the tree in a moment of greed or folly. The massive trunk crashed to the earth, unleashing a terrible flood, and the sheer, flat-topped stump that remained became Mount Roraima. This powerful myth beautifully explains the "cut" appearance of the tepui without the need for alien lasers or lost technological empires. It highlights a profound spiritual connection to the geological landscape.
The folklore surrounding Mount Roraima is not merely a collection of ancient bedtime stories; it is a vital part of indigenous identity. The mountain is considered sacred ground, heavily protected by spirits, and historically, scaling its walls was strictly forbidden. The mists that perpetually shroud the summit are said to be the smoke from the fires of the spirits. This deep-rooted reverence demonstrates how ancient humans naturally created complex, mythical frameworks to make sense of the awe-inspiring and intimidating geological anomalies of their environment.

While the theory of artificial cuts remains firmly in the realm of alternative history, there is undeniable evidence of ancient human presence in the shadow of Mount Roraima. Recent archaeological expeditions have begun to reveal that the seemingly impenetrable Canaima National Park complex was not entirely devoid of early human activity. Although the brutal environment makes the preservation of organic material difficult, researchers have found enduring marks left in stone. A 2026 study by García et al. documented the exciting discovery of new rock art sites and lithic tools in the region.

These recent findings provide a tangible link between the modern indigenous populations and their prehistoric ancestors. The newly discovered petroglyphs feature intricate geometric patterns, human figures, and representations of the diverse local fauna. The presence of these ancient artists suggests that the area around Mount Roraima has been a site of cultural significance for thousands of years. The lithic tools found nearby indicate that these ancient people were not just passing through, but were actively hunting, gathering, and surviving in this challenging environment.

The discovery of prehistoric rock art adds a crucial layer of authenticity to the region's historical narrative. It shifts the focus from unsubstantiated claims of advanced ancient engineering to the very real, hard-fought survival of indigenous groups in South America. These ancient people did not need advanced machinery to leave their mark on the world. Their legacy is etched into the stone faces of the Gran Sabana, proving that the true magic of Mount Roraima lies not in hypothetical artificial cuts, but in the enduring relationship between the mountain and the humans who have revered it since antiquity.
Ultimately, Mount Roraima stands as a testament to the staggering power of geological forces and the boundless capacity of human imagination. Whether viewed as the petrified stump of the Tree of Life, a naturally sculpted masterpiece of quartz sandstone, or a canvas for prehistoric artists, it remains one of the Earth's most mesmerizing mysteries. While the vertical cliffs were carved by water and time rather than ancient saws, the true wonder of Mount Roraima is that it continues to inspire a profound sense of awe in everyone who gazes upon its towering walls.

EXCLUSIVE - I'm an exorcist... Here's the chilling encounter that made me believe UFOs are the work of Satan
EXCLUSIVE - I'm an exorcist... Here's the chilling encounter that made me believe UFOs are the work of Satan
By ROB WAUGH
A Catholic priest and exorcist who has encountered demons first-hand has revealed a chilling experience that led him to believe UFOs are actually the work of the devil.
Father Carlos Martins, an Ontario-born priest who has performed exorcisms around the world, believes the UFO phenomenon is part of a larger spiritual deception designed to undermine Christianity and cast doubt on the Bible.
The priest said a longtime friend who later converted to Christianity once witnessed a gigantic spacecraft hovering silently over a suburban park before it shot away 'instantly to the speed of a bullet.'
The object was allegedly so enormous that the two witnesses could see details on its surface and estimated it stretched across 'many football fields in size.' Yet despite the extraordinary sighting, no one else in the town appeared to notice the object, and there were no local news reports about the alleged encounter.
Years later, after converting to Christianity, Martins' friend came to believe the vision had not been an alien craft at all, but a supernatural illusion sent by the devil.
Speaking to the Daily Mail, Martins said Satan could use belief in extraterrestrial civilizations to create 'a competing account' to Christian scripture and weaken belief in divine revelation.
He also claimed modern UFO encounters, particularly alien abduction stories, often mirror the psychological and physical torment seen during cases of alleged demonic possession.
'If the devil brings it about, he can put it into the human imagination that there is extraterrestrial life, that there are civilizations out there, then he can cause doubt in the Scriptures,' Martin said.
Father Carlos Martins has encountered the Devil and his minions in many forms
'What he's done then is set up a competing account to the Christian scriptures, something the Judeo-Christian scriptures cannot account for, and so there's an indirect repudiation of the truth of revelation. He's accomplished that.'
The idea that UFOs may have demonic origins has gained traction in some conservative religious circles in recent years.
Vice President J D Vance said on a podcast in March: 'I don't think they're aliens, I think they're demons.'
Martins converted from atheism to Christianity while studying as an undergraduate and says one of his closest friends experienced an encounter that radically shaped his understanding of UFOs.
The priest recalled: 'I have a good friend who is a convert. He converted to the Christian faith in his late teens or early 20s. We grew up in the same hometown.
'[My friend] was walking with another friend on a weeknight along a trail in a suburb that ran between two homes and opened into a large park.
'They looked up into the sky and saw this enormously large spaceship. It was immensely large, many football fields in size.'
The two men allegedly watched the giant craft hovering silently overhead and were close enough to make out details on its surface.

Martins said: 'They look at one another, and then they look back at the ship, and it would have been less than a minute.
'All of a sudden, it takes off with a speed that's just unfathomable, instantly to the speed of a bullet. So it just shot out of the sky. There wasn't an acceleration, it was just instant darting away.'
According to Martins, the most disturbing aspect of the encounter was that nobody else seemed to have witnessed the gigantic craft.
There were no reports in local newspapers, no emergency calls and no indication anyone else in town had seen the alleged spacecraft.
For years, his friend struggled to understand the experience until later converting to Christianity.
'My friend, when he converted, or after he converted, we talked about this again, Martins said.
'I remember a couple of times, and I said to him, "Look, what do you think that was?" He said, "No question. It was the devil."'
'He said, "If I were to buy into this concept, then of their being ET life, then it would cast a doubt on the Christian account of what exists in the universe of God's plan for it."'
He said reports involving UFOs and alien encounters have increasingly appeared alongside exorcism cases during the last decade.
'There's definitely been a rise, I would say, in the last 10 years of integration of UFO and extraterrestrial, alien life stuff and exorcism,' Martins explained.
'I wouldn't say that it's common, but I would say it's definitely on the rise.'

Martins believes many UFO sightings are elaborate illusions created to deceive human senses.
'The senses can be deceived. Fake sense experience can be produced. That's the point,' he said. 'So an illusion, a mirage, which I've seen many times.'
The priest said he witnessed this phenomenon firsthand while performing an exorcism on a firefighter he believed was possessed.
Martins said he secretly flicked a tiny amount of holy water onto the man's clothing while walking behind him.
According to Martins, the man suddenly reacted violently.
'He shot up out of his chair and started hissing, and his teeth seemed to grow some two inches, like there were fangs at that moment,' Martins said. 'For a split second, the fangs were protruding from his mouth.'
Martins believes the apparent transformation was not physically real, but rather a visual illusion generated by demonic forces.
'The devil is perfectly capable of bending light. He's perfectly capable of causing a mirage and illusion,' the priest said. 'I mean, he is by far the greatest magician, the greatest sleight of hand performer that has ever existed.'
The priest also argued that alleged alien abductions closely resemble accounts of demonic oppression and possession.
'When you read accounts of abductions of people that have been allegedly abducted, very similar to ones that are demonically tortured,' Martins said. 'There are large gaps in memory.'
He added: 'The phenomenon, the experience of the victim, is kind of always the same. Across the board, there's an abuse of the body, an abuse of the person.'
Martins believes modern fascination with extraterrestrials emerged during the Space Age and gradually replaced older supernatural folklore.
'This is the modern-day folk account of leprechauns, tooth fairies and pixies,' he said. 'It was only when we entered the Space Age.
'Then the view of man changed, and that became kind of the new realm, the blank slate by which the devil could approve and kind of begin to dictate a new story.'

Aliens on Anlaby school roof and ETs sending invisible cars to Goole - the weird tales unearthed by UFO investigator
It was not long after the Christmas holidays on a Wednesday in 1978 at Anlaby Primary School when "Peter" - a pseudonymous pupil - is reported to have had a close encounter of the third. Later that day, the seven year old told his puzzled mum that, while in the playground, he had heard a sharp whistling noise and looked up to see a flying saucer that was changing colour as it came in to land on the school's flat roof.
Three humanoid beings are said to have got out of the craft - they appeared to be armless and wearing gold suits with wires or tubes hanging from their backs which connected them to the craft. Peter ran off to tell a friend but looked back to see the beings had got back into the craft - which took off slowly before flying away "like a boomerang" once it had cleared nearby buildings
Peter's sighting - only a couple of months before Steven Spielberg's blockbuster Close Encounters Of The Third Kind hit British cinemas - is just one of several bizarre accounts from the Humber region researched by Scunthorpe UFO investigator Nigel Watson, who has spent much of his life peering into people's experience of the phenomenon.
Now, with the US Government's release of so-called UFO files and supposed whistleblowers coming forward in recent years, Nigel has highlighted several astonishing tales from his book - Portraits Of Alien Encounters Revisited: High Strangeness British UFO Cases - which was published last year and includes cases predominantly from the 1970s and 80s.
Nigel, who was a founder of the Scunthorpe UFO Research Society in the early 1970s, was drawn to the subject amid the space race in the '60s and began interviewing people from across the North of England, who claimed to have seen mainly anomalous lights in the sky. Many, he supposes, were actually satellites, flares or other more pedestrian explanations.

But, for Nigel, a handful of really incredible stories stuck out - with some reported on his doorstep. The Anlaby encounter came only months after the eerily similar Wawne Primary case.
Nigel explained: "Children saw a craft fly over their school. The headmaster got them to do drawings and plasticine models afterwards, and they all seemed to be very similar."
On the same day, 12 miles to the North West of Wawne, a mother and her seven year-old son were going to the youth club at Middleton when they saw a brilliant cone of blue light. They reported it travelling silently at high speed, and that as it moved it got larger. Nigel says the boy's description of it as "like a rocket" suggests they saw a meteor or fireball.
Nigel, who describes himself an "optimistic sceptic", said: "I think the accounts change on the basis of what they think aliens should look like. In the early years, people always seemed to report aliens in space suits with helmets and taking samples.
"Of course, that's exactly what the Apollo astronauts were doing on the moon. It's quite logical, but after Spielberg's film, it's been more about these 'greys', which don't wear space suits. The way people perceive aliens seem to be influenced by things like films and that might be because people see something ambiguous and then interpret it as an alien."
Another locally specific chapter in the book concerns a man from Hull who said he said he faced a number of disturbing experiences through practising meditation. The pseudonymous "Martin", who had owned his own company in the city, talked of being invited by aliens to ride in a UFO, with him being sent to meet an invisible vehicle in a field near Goole which would take him to the craft.
Even though that case Nigel surmises to be based on the man's imagination and psychological turmoil, he says not all bizarre reports can be dismissed out of hand.
He added: "I suppose over the years I've got more sceptical, but I'm still fascinated by the subject. There's some fantastic accounts in my book and people do think they have had these experiences. I think you have to respect what people believe in."
What is light, and in what ways does a laser differ from a flashlight?
Have you ever contemplated the differences between a laser and a conventional flashlight? Addressing this inquiry necessitates a succinct historical overview and a detailed examination of the nature of light. This will be the focus of our discussion now.

May 16 is observed as the International Day of Light, initiated by the United Nations. This date is not arbitrary; on this day in 1960, Theodore Maiman first demonstrated the operation of a solid-state laser. One might inquire why the date was not chosen to coincide with the invention of the electric light bulb or a flashlight based upon it. The response to this inquiry prompts a counter-question: how does a flashlight fundamentally differ from a laser? Can a laser be considered a type of flashlight? And what precisely is light? Let us commence with this final question.
Since antiquity, humans have been captivated by the nature of light. As early as the 5th century BC, the ancient Greek philosopher Empedocles examined concepts related to rays and their origins. Two centuries thereafter, Euclid provided a mathematical description of the laws governing light reflection. Subsequently, Ptolemy investigated the phenomena of light refraction.

However, no one was able to elucidate the composition of the sunlight or the stars observed. It was not until 77 B.C. that the ancient Roman scholar Lucretius proposed that light consists of a stream of particles interacting with the human eye. Nevertheless, other ancient writers were gradual in accepting this theory.
This concept did not become widely popular until the subsequent millennium, and it was Indian and Arab scholars — not European researchers — who were the initial adopters.
Nevertheless, by the 17th century, the theory that light consisted of a stream of very small particles (corpuscles) had already become predominant in European science. The initial experiments validating this theory had already been performed. However, Francesco Grimaldi subsequently discovered the phenomena of light interference and diffraction, leading to the conclusion that light is a wave — a vibration that propagates through a medium filling all of space, which was then referred to as the ether. Over the following three centuries, numerous experiments were undertaken: some unequivocally confirmed that light is particulate, while others convincingly demonstrated that it is a wave.

The debate regarding the nature of light was among the most comprehensive in global history. It was not resolved until the early twentieth century. Initially, investigations into the internal structure of the atom suggested that electrons sometimes exhibit behavior characteristic of both particles and waves.
Albert Einstein then utilized these theories to elucidate the photoelectric effect — a phenomenon wherein light incident on specific materials induces an electric current to flow within a closed circuit connected to them. It is this very phenomenon that forms the fundamental basis for the operation of contemporary solar panels and photovoltaic cell-based motion sensors.
Einstein elucidated the photoelectric effect by stating that an electron cannot orbit the nucleus of an atom in arbitrary paths, but only along specific trajectories, with the differences between these paths corresponding to precisely defined quantum of energy. It is these quanta of energy that the electron absorbs upon collision with a photon. If, subsequently, the electron transitions to a sufficiently excited state, it commences movement from one atom to another. This process is the mechanism by which an electric current is generated.

Interestingly, Einstein’s original papers from 1905 to 1917 do not use the modern name for the particle — the photon. That term was proposed by Gilbert Lewis in 1926. Einstein himself referred to it specifically as a “light quantum.”
The recognition of a particle of light as a quantum has definitively resolved the longstanding debate regarding its fundamental nature. Indeed, photons, along with all other elementary particles, demonstrate wave-particle duality. In essence, they can exhibit momentum and a trajectory of motion akin to a ballistic object, while simultaneously possessing frequency and amplitude characteristic of a wave in the ocean.
Concurrently, a photon’s energy is contingent upon its frequency, and not on its amplitude. Moreover, it certainly does not depend on mass, as photons inherently lack mass. It is due to this fact that photons in a vacuum consistently travel at the maximum attainable velocity within our universe: 299,792,458 meters per second. This velocity is commonly referred to as the speed of light.

Another notable feature of the photon is that it possesses no intrinsic electric charge. Nevertheless, it functions as a mediator of electromagnetic interaction. In fact, visible light constitutes only a minor segment of the electromagnetic spectrum, which extends from radio waves to gamma rays.
It is unsurprising that photons are represented by the Greek letter γ, which is also used for the most intense form of radiation. This correspondence arises because they are essentially identical particles, distinguished only by their varying energies. Similarly, the same principle applies to infrared and ultraviolet light.
In conclusion, our Sun emits photons across a broad spectrum. The most hazardous portion of this radiation is effectively obstructed by our planet’s magnetic field and ozone layer. Of the remaining radiation, we perceive only photons with wavelengths between 400 and 780 nanometers. Consequently, what we observe as visible light is, in fact, a composite of particles with varying frequencies, given that this attribute is inversely proportional to wavelength.
You may observe this phenomenon firsthand by witnessing light disperse into a spectrum. In the natural environment, this process is quite commonplace, with its most prevalent form being the one produced by numerous water droplets suspended aloft in the sky. This optical phenomenon is commonly known as a rainbow.

Light is also dispersed into a spectrum within various containers filled with water. However, this process is typically executed intentionally through the use of prisms. The fundamental principle involves employing reflection and refraction to cause particles, which were previously traveling in unison, to diverge at different angles. These variations are perceived as distinct colors.
Our chromatic perception functions in a comparable manner with regard to the surrounding objects. When an object absorbs all photons within the visible spectrum except for a narrow band that is reflected, we perceive it as possessing a particular color.
With colored light produced by a transparent medium — such as in stained glass — the principle is similar, but with a slight difference. In that case, the material also absorbs most of the visible spectrum, but the remainder is not only reflected but also transmitted through it.
Once the nature of light was comprehended, individuals initiated the pursuit of more advanced techniques for its generation. Historically, the prevalent approach entailed the utilization of heated objects or gaseous byproducts resulting from exothermic reactions. Furthermore, heat represents a manifestation of electromagnetic interaction, transmitted via photons.

In the case of an open flame, this is not immediately apparent, as it is necessary to first understand that the combustion reaction initially generates a dense cloud of hot gases (the flame), which emits photons. Concurrently, because the transfer of energy between electrons and atomic nuclei occurs in a chaotic manner, the photons produced possess a range of frequencies and energies.
Consequently, any object subjected to sufficient heating emits photons. However, not all photons possess a frequency within the visible light spectrum. An example of this can be observed in infrared thermal imaging cameras. Their remarkable capability to operate effectively in darkness is merely a result of detecting low-frequency photons and transforming the resulting image into a visible format.
Another example is heating metal until it glows. Typically, this produces a red color. The reason is that the hotter a body gets, the higher the frequency of the emitted photons becomes. And the first color in the visible spectrum that they encounter is red. To produce other colors, the material must be heated to a temperature at which most metals melt or react with atmospheric gases.
Energy distribution in an incandescent lamp. Source: Wikipedia
However, individuals discovered alternative methods to circumvent this limitation even prior to Einstein’s establishment of the quantum nature of light. The solution involves a tungsten filament, which is integrated into an electrical circuit and mounted within a glass vacuum bulb. This device is referred to as an incandescent lamp, and until recently, it represented the most prevalent method for illuminating residential spaces.
The most intriguing aspect of this method is that, owing to its imperfections, the spectrum of photons generated when an electric current traverses a filament exhibits a slight shift toward the red end of the spectrum in comparison to sunlight. However, this characteristic has become so familiar to us that it is commonly referred to as “warm incandescent light.”
Nevertheless, in contemporary practice, we predominantly employ lighting fixtures that utilize more energy-efficient LED technology. Indeed, an incandescent bulb is so designated because it primarily emits energy in the infrared spectrum, which does not contribute to enhancing indoor illumination.
In fact, Light Emitting Diodes (LEDs) emit blue light, which is subsequently transformed into white light.The underlying principle of the energy efficiency of Light Emitting Diodes (LEDs) resides in the fact that photons are emitted not during the excited state of atoms, but as a consequence of electron transitions between different types of semiconductors. The nature of these transitions is dictated by the composition of the materials involved. The energy of the emitted photons remains constant, resulting in the emission of light of a singular color.
The paradox lies in the fact that it cannot be considered the “white sunlight” it appears to be, such as when a flashlight is turned on. This is because, as previously noted, sunlight itself is a combination of various wavelengths.
In reality, no LED is truly white. It is either a blue LED coated with a yellow phosphor that emits yellow light, together producing the desired color, or it consists of three separate LEDs — red, green, and blue — that collectively generate the same effect.
This raises the question: Is it even feasible to produce a light source capable of generating the purest possible electromagnetic waves across any frequency spectrum? The answer is the laser. More precisely, the answer resides in the principle of stimulated emission of photons, which underpins its operation.
All the light sources described heretofore emit photons passively, as a consequence of other processes. However, Einstein himself proposed as early as 1916 that electrons could be induced to emit photons collectively simply by prompting their transition from one orbital level to another.
For this phenomenon to occur consistently, it is essential that the majority of atoms within a given volume be in an excited state. Additionally, the environment in which the process occurs must be enclosed by a mirrored surface capable of reflecting photons. As a result, the number of photons within the generator will continuously increase, and it is then sufficient to leave a single narrow aperture through which they can pass, thereby producing a beam of intense radiation.
A distinguishing characteristic of such a system is that, akin to LEDs, all emitted photons possess identical frequencies. Nevertheless, a notable distinction exists between them. Spontaneous emission in semiconductors transpires with phase and directional mismatches. Conversely, in a laser beam, all electromagnetic oscillations are flawlessly superimposed. This phenomenon is termed coherence, and it fundamentally differentiates a laser from all other sources of light.

Recall the initial stages of our study on light? It began with rays. However, rays emanating from all light sources gradually diverge in every direction as they propagate, and at a certain distance, they form a large spot. In contrast, with lasers, due to their coherence, this process occurs at a significantly slower rate.
This is precisely why they are utilized as indicators. The concept underlying beam weapons similarly relies on this principle, as well as on the fact that pumping a medium can produce a significantly large number of photons. Furthermore, a high photon density per unit cross-sectional area of the beam corresponds to a substantial amount of energy being transferred to the material.
In essence, the laser is regarded as the most exemplary source of illumination ever developed by mankind. It is therefore not surprising that the United Nations designated the date of its initial demonstration as World Light Day. After all, it was at that juncture that humanity achieved comprehensive mastery over this enigmatic phenomenon, the nature of which had been subject to debate for centuries.
