There’s something poetic about humanity’s attempt to detect other civilizations somewhere in the Milky Way’s expanse. There’s also something futile about it. But we’re not going to stop. There’s little doubt about that.

One group of scientists thinks that we may already have detected technosignatures from a technological civilization’s Dyson Spheres, but the detection is hidden in our vast troves of astronomical data.

A Dyson Sphere is a hypothetical engineering project that only highly advanced civilizations could build. In this sense, ‘advance’ means the kind of almost unimaginable technological prowess that would allow a civilization to build a structure around an entire star. These Dyson Spheres would allow a civilization to harness all of a star’s energy.

A Civilization could only build something so massive and complex if they had reached Level II in the Kardashev Scale. Dyson Spheres could be a technosignature, and a team of researchers from Sweden, India, the UK, and the USA developed a way to search for Dyson Sphere technosignatures they’re calling Project Hephaistos. (Hephaistos was the Greek god of fire and metallurgy.)

They’re publishing their results in the Monthly Notices of the Royal Academy of Sciences. The research is titled “Project Hephaistos – II. Dyson sphere candidates from Gaia DR3, 2MASS, and WISE.” The lead author is Matías Suazo, a PhD student in the Department of Physics and Astronomy at Uppsala University in Sweden. This is the second paper presenting Project Hephaistos. The first one is here.

“In this study, we present a comprehensive search for partial Dyson spheres by analyzing optical and
infrared observations from Gaia, 2MASS, and WISE,” the authors write. These are large-scale astronomical surveys designed for different purposes. Each one of them generated an enormous amount of data from individual stars. “This second paper examines the Gaia DR3, 2MASS, and WISE photometry of ~5 million sources to build a catalogue of potential Dyson spheres,” they explain.

Combing through all of that data is an arduous task. In this work, the team of researchers developed a special data pipeline to work its way through the combined data of all three surveys. They point out that they’re searching for partially-completed spheres, which would emit excess infrared radiation. “This structure would emit waste heat in the form of mid-infrared radiation that, in addition to the level of completion of the structure, would depend on its effective temperature,” Suazo and his colleagues write.

The problem is, they’re not the only objects to do so. Many natural objects do, too, like circumstellar dust rings and nebulae. Background galaxies can also emit excess infrared radiation and create false positives. It’s the pipeline’s job to filter them out. “A specialized pipeline has been developed to identify potential Dyson sphere candidates focusing on detecting sources that display anomalous infrared excesses that cannot be attributed to any known natural source of such radiation,” the researchers explain.

This flowchart shows what the pipeline looks like.

The pipeline is just the first step. The team subjects the list of candidates to further scrutiny based on factors like H-alpha emissions, optical variability, and astrometry.

368 sources survived the last cut. Of those, 328 were rejected as blends, 29 were rejected as irregulars, and 4 were rejected as nebulars. That left only 7 potential Dyson Spheres out of about 5 million initial objects, and the researchers are confident that those 7 are legitimate. “All sources are clear mid-infrared emitters with no clear contaminators or signatures that indicate an obvious mid-infrared origin,” they explain.

These are the seven strongest candidates, but the researchers know they’re still just candidates. There could be other reasons why the seven are emitting excess infrared. “The presence of warm debris disks surrounding our candidates remains a plausible explanation for the infrared excess of our sources,” they explain.

But their candidates seem to be M-type (red dwarf) stars, and debris disks around M-dwarfs are very rare. However, it gets complicated because some research suggests that debris disks around M-dwarfs form differently and present differently. One type of debris disk called Extreme Debris Disks (EDD) can explain some of the luminosity the team sees around their candidates. “But these sources have never been observed in connection with M dwarfs,” Suazo and his co-authors write.

That leaves the team with three questions: “Are our candidates strange young stars whose flux does not vary with time? Are these stars’ M-dwarf debris disks with an extreme fractional luminosity? Or something completely different?”

“After analyzing the optical/NIR/MIR photometry of ~5 x 10⁶ sources, we found 7 apparent M dwarfs exhibiting an infrared excess of unclear nature that is compatible with our Dyson sphere models,” the researchers write in their conclusion. There are natural explanations for the excess infrared coming from these 7, “But none of them clearly explains such a phenomenon in the candidates, especially given that all are M dwarfs.”

The researchers say that follow-up optical spectroscopy would help understand these 7 sources better. A better understanding of the H-alpha emissions is especially valuable since they can also come from young disks. “In particular, analyzing the spectral region around H-alpha can help us ultimately discard or verify the presence of young disks,” the researchers write.

“Additional analyses are definitely necessary to unveil the true nature of these sources,” they conclude.

UFO Technology: A Renewed Push to Unveil Government Secrets

In recent developments, a significant push to disclose top-secret government files on UFO sightings has emerged, spearheaded by Senate Democratic leader Chuck Schumer. This initiative not only aims to unveil hidden data but also to delve deeper into the enigmatic realm of non-human technologies potentially held by private entities such as Lockheed. The drive for transparency is rooted in a broader history of political efforts to understand and harness technologies beyond our current scientific grasp.

Former State Department analyst Marik Von Rennenkampf has brought this issue into the spotlight, outlining the intricate dance of politics and secrecy that has long shrouded UFO-related programs. According to Von Rennenkampf, the initiative echoes past attempts by political figures such as Nevada Senator Harry Reid, who, alongside others, previously sought to establish a highly secretive program. Their goal was ambitious: to reverse-engineer non-human technology that was believed to be in the possession of private contractors, thereby leapfrogging technological limitations that have stalled advancements in public sectors.

This narrative is not new; it has evolved over decades. In the 2010s, Senator Reid, with support from other influential senators, including Joe Lieberman, attempted to centralize control of these materials to study and possibly replicate their technological essence. Despite their efforts, formal acknowledgment or success of such programs remains undocumented, with government departments historically shutting down these initiatives before any significant breakthrough could occur.

Today, the conversation has been reignited by Schumer, who has publicly expressed concerns about government transparency and accountability in handling UFO-related information. Allegations have surfaced that certain government sectors have withheld crucial information from Congress, fueling a mistrust that complicates the political landscape around UFOs. Schumer’s initiative is part of a broader legislative effort, proposing that recovered non-human crafts are of significant interest and should be subject to governmental review and public oversight.

This new legislative push aims not only to uncover any concealed UFO recovery programs but also to legislate the handling of such sensitive materials. If the proposed legislation passes, it could pave the way for new standards in how such potentially revolutionary technologies are managed, potentially altering the technological and political landscape dramatically.

As the debate unfolds, the public and policymakers alike are watching closely. The implications of such disclosures are profound, not just for national security but for our understanding of what technological marvels might lie beyond our current capabilities. The ongoing efforts to demystify the government’s UFO-related secrets continue to provoke both curiosity and controversy, suggesting that what may be unearthed could challenge the very boundaries of modern science and technology.

Near-Collapse of Geomagnetic Field May Have Contributed to Diversification of Life on Earth

An ultra-weak geomagnetic field between 591 and 565 million years ago (Ediacaran period) coincided with a significant increase in the oxygen levels in the atmosphere and oceans, says a research team led by University of Rochester geoscientists.

Earth’s magnetic field was in a highly unusual state when macroscopic animals of the Ediacara Fauna diversified and thrived.

Image credit: NASA.

Between 600 and 540 million years ago, life on Earth consisted of soft-bodied organisms known as the Ediacaran Fauna, the earliest known complex multicellular animals.

The fossil record shows that these organisms significantly diversified in complexity and type between 575 and 565 million years ago

Previous research has suggested that this diversification is linked to a significant increase in atmospheric and oceanic oxygen levels that occurred over the same period.

However, it is not yet clear why this increase in oxygen occurred.

In the new study, University of Rochester’s Professor John Tarduno and colleagues analyzed the magnetic properties of 21 plagioclase crystals, a common mineral in Earth’s crust, which were extracted from a 591-million-year-old rock formation in Brazil.

Plagioclase crystals contain tiny magnetic minerals which preserve the intensity of the Earth’s magnetic field at the time they are formed.

An analysis of the crystals showed that, at their point of formation, the Earth’s magnetic field was the weakest ever recorded — some 30 times weaker than both the current magnetic field intensity, and that measured from similar crystals formed approximately two billion years ago.

The scientists combined their results with previous measurements to establish that the Earth’s magnetic field was at this weak level for at least 26 million years, from 591 to 565 million years ago.

This overlaps with the rise in oxygen, which occurred between 575 and 565 million years ago.

“The weakened magnetic field may have allowed more hydrogen to escape to space, resulting in a greater percentage of oxygen in Earth’s atmosphere and oceans, which may in turn have supported the diversification in the types and complexity of organisms,” the authors concluded.

Krachtige zonne-explosies hebben een sterke impact op de aarde: wat zou er kunnen gebeuren?

 Door Janine

De krachtige uitbarstingen die op onze moederster exploderen, hebben een sterke impact op de aarde en lijken niet te stoppen. Dit is wat er gebeurt.

Wat zijn zonnevlammen?

SPACE WEATHER PREDICTION CENTER

Een zonnevlam, zo meldt NASA, is "een intense uitbarsting van straling door het vrijkomen van magnetische energie die gepaard gaat met zonnevlekken". Dit zijn, legt de Amerikaanse ruimtevaartorganisatie uit, de grootste explosieve gebeurtenissen in ons zonnestelsel. Ze manifesteren zich als heldere gebieden op de zon die enkele minuten tot enkele uren zichtbaar zijn.

Wat ons in staat stelt om ze te detecteren is het licht, dus de fotonen, die vrijkomen en die worden gecontroleerd door optisch licht en röntgenstraling. In zonnevlammen worden de zwaarste deeltjes versneld. De afgelopen dagen zijn zonnevlammen in volle actie: X1.6 vond plaats op 3 mei, gevolgd door andere krachtige fenomenen volgens het Space Weather Prediction Center van NOAA. Elk van deze fenomenen heeft een grote impact gehad op onze planeet.

De gevolgen van krachtige zonnevlammen op aarde

Een X1.3 en een X1.2 zonnevlam barstten op 5 mei los uit de actieve groep zonnevlekken AR 3663. In beide gevallen traden radio blackouts op op onze planeet, in Japan, Australië en grote delen van China, en de effecten zouden langer kunnen duren als coronale massa uitstoot, enorme wolken van zonneplasma doordrenkt met magnetische veldlijnen, geladen deeltjes naar de aarde zouden leiden.

Hierover zijn echter geen zekere gegevens bekend. Er zijn momenteel negen clusters zonnevlekken aanwezig aan de kant van de zon die naar onze planeet is gericht, die ongeveer 150 zonnevlekken omvatten. AR 3663 is op dit moment in ieder geval het meest actief en heeft sinds 30 april meerdere M-klasse en vier X-klasse vlammen uitgezonden, waarmee hij op de tweede plaats staat van de sterkste vlammen die onze ster kan produceren.

Maar wat zijn de voorspellingen van de wetenschappers en wat kunnen we verwachten? Volgens de voorspellers zullen er meer M-klasse vlammen zijn en mogelijk nog een of meer X-klasse vlammen voordat ze buiten de baan van de aarde draaien.

Keith Strong, een zonnefysicus, schreef in een bericht op X, voorheen Twitter: “Het gebied van zonnevlekken AR3663 produceerde een X4.5 vlam, de op twee na grootste sinds het begin van zonnecyclus 25 (4,3 jaar geleden)." Hij voegde eraan toe dat de vlam een sterke black-out veroorzaakte in een groot deel van Azië, Oost-Afrika en Oost-Europa. "Als het een coronale massa uitstoot produceerde, zal deze waarschijnlijk binnen een dag of twee de aarde raken."

Geomagnetische storm op komst? Er is iets positiefs aan

SDO | Solar Dynamics Observatory NASA

Zonnevlammen gaan soms gepaard met uitbarstingen die de aarde met een paar dagen vertraging kunnen bereiken, omdat plasma zich minder snel verplaatst dan licht. Op het moment dat de coronale massa uitstoot ons bereikt, ontstaat er echter een geomagnetische storm met aanzienlijke gevolgen voor de communicatie. Op het moment dat het de magnetosfeer van de planeet raakt, ontstaan er elektrische stromen die door elektriciteitsnetwerken kunnen reizen, stroomuitval kunnen veroorzaken en satellieten, radio- en navigatiesignalen kunnen beïnvloeden.

Maar er is ook een positief aspect: de wisselwerking tussen zonnedeeltjes, de magnetosfeer en de atmosfeer van de aarde leidt tot een opvallend poollicht boven de polen van de aarde, dat alleen 's nachts zichtbaar is, wanneer er geen zonlicht is. In elk geval zullen de volgende uitbarstingen kleine gevolgen hebben, omdat AR 3663 van de baan van de aarde af draait, maar de zon zit midden in haar activiteitscyclus, haar piek vindt om de elf jaar plaats en kan ons nog meer “verrassingen” bezorgen.

The sun appears to be angry; a massive coronal mass ejection unveils a striking image resembling a grimacing demonic face. Striking are the letters DV (DeVil?) standing out on the forehead of the figure. 

Obviously, the strange phenomenon captured by NASA's solar satellite SOLO EUI HRI 174 on 2024/05/11 is an ordinary natural occurrence triggered by the eruption of solar material but a fact is that a huge CME hit Earth's magnetic field on May 10th, leading up to the biggest geomagnetic storm in almost 20 year. 

And it is not yet over as forecasts predict additional coronal mass ejections to follow closely behind, prolonging the storm well into the weekend. Anticipation mounts for widespread auroras, promising captivating displays over regions like Europa and the United States. 

The storm has now reached level G5 which is the strongest level of geomagnetic storm, on a scale from G1 to G5. The solar storm could lead to disruption of satellite communication systems, low-frequency radio navigation systems such as GPS or even widespread power grid failures. 

This unique solar phenomenon emphasizes once more the importance of constant monitoring and readiness in response to solar disruptions in order to prevent another Carrington event which was the most intense geomagnetic storm in recorded history, peaking from 1–2 September 1859.

The Truth About UFOs: Insights from a Former Top Secret Government Investigator

The mysteries surrounding Unidentified Flying Objects have long intrigued both the public and experts alike. Among the most compelling investigations into these enigmatic phenomena was Project Blue Book, a top-secret government program tasked with exploring thousands of UFO encounters from 1952 until its closure in 1970. A renewed interest in one of its most mysterious cases has surfaced, shedding light on an incident that has puzzled enthusiasts for decades—the 1965 Kecksburg UFO sighting.

In a recent exploration into this historic event, UFO investigator Ben Hansen delved into the archives and testimonies preserved by Jenny Zideman, the last remaining member of Project Blue Book. Jenny, who meticulously kept files on numerous UFO sightings, provided crucial insights into the Kecksburg incident, which occurred on December 9, 1965.

The small town of Kecksburg, Pennsylvania became the epicenter of intrigue when locals reported seeing a fireball tearing across the sky, eventually crashing into a nearby wooded area. Witnesses described the object as large, metallic, and acorn-shaped, surrounded by a haze of colorful lights—an anomaly that was later casually dismissed by the military as a mere meteor. However, those who saw it firsthand firmly believed it was something far more significant; a craft from another world.

Decades later, the event continues to evoke curiosity and speculation. Recent UFO sightings in the area, eerily reminiscent of the 1965 event, prompted Hansen to reexamine the original files with the help of Zideman. During their investigation, they also collaborated with UFO historian Mark O’Connell, and together they scrutinized a specific file that concluded the incident was caused by a meteor—a conclusion now widely criticized for its inadequacy in explaining the witnessed phenomena, such as the object’s apparent ability to change course in mid-flight.

Moreover, Hansen interviewed eyewitnesses like Ron Strubel and Bill Weaver, who not only confirmed the sighting but also described subsequent military activities that seemed to contradict the official explanations. Strubel, who was interviewed by Project Blue Book at the time, led Hansen to the crash site, offering a firsthand recount of the military’s rapid response and the mysterious proceedings that followed. Weaver’s account added to the intrigue, detailing a large military presence and the appearance of personnel in ‘moon suits,’ suggesting a recovery operation of something other than a mere meteorite.

These accounts fuel the debate about whether the government has been concealing the truth about UFOs. According to Zideman, such secrecy could indicate a vulnerability— an acknowledgment of our limited defense against more technologically advanced entities. This sentiment was mirrored in the eyewitness descriptions and the historian’s skepticism toward the meteor theory.

As interest in the Kecksburg incident rekindles, it begs a broader question: how much do we truly know about the objects that traverse our skies? Are they simply natural phenomena, or evidence of extraterrestrial visitations? While the government’s stance on UFOs has historically been one of skepticism and dismissal, cases like Kecksburg continue to challenge the official narrative, inviting us to consider the possibilities that lie beyond our current understanding.

The ongoing quest for truth in the realm of UFOs not only captivates the imagination but also underscores the need for transparency and rigor in investigating the unknown. As we stand on the brink of new discoveries, it is crucial that both the public and experts maintain an open dialogue, relentlessly seeking the truth hidden within the shadows of secrecy.

Bizarre UFO Encounter Of US Farmer: Three Aliens Gave Him Pancakes

Joseph Simonton, a poultry farmer was sixty years old at the time of his encounter with a flying saucer. He reportedly received some pancakes as a gift from the ETs who were inside that craft. The farmer lived near Eagle River, Wisconsin, United States.

On April 18, 1961, Simonton was having breakfast in the late morning in his home when he heard a confusing noise near his farm. He looked out his window and stunned after seeing a silver disc hovering over his backyard. The UFO was four meters high and 10 meters in diameter.

Simonton was rather curious to check on the object than shocked. When he stepped outside, a hatch on the disc opened and three dark-skinned humanoid figures appeared. According to the farmer, they were mute and looked like the Italian. The aliens were about five feet tall, dressed up in tight clothes from head to toes.

• Ex-USAF Captain: UFOs Hacked Malmstrom AFB Nuke System, Deactivated 10 Missiles

The man said that one of the aliens had some vessel (like a bucket) and signaled him to fill it with water. He took the bucket, filled it with the water from the nearby pump, and returned it to the alien. Simonton noticed that inside the ship, it was totally dark and one of the ship’s crew was busy with the dashboard while others seemed to be prepared for cooking on a flameless grill. The creatures looked nice and offered him four pancakes that had tiny holes. After that, they closed the hatch, started the ship, slowly rose it some distance from the ground, and flew away tow ard the south. Simonton, holding four pancakes, watched this amazing scene with his eyes wide open.

Interestingly, at the same time, this incident caught one more witness. Savino Borgo, an insurance agent who was driving near Simonton’s farm,so saw a al flying saucer.

Simonton tasted one of the pancakes but was not impressed by the friendly aliens’ cooking. According to him, it tasted like cardboard. Normally, such stories are called fake due to their bizarre nature but this one got the attention of the US authorities. After the neighbors spotted a UFO over Simonton’s farm, they called the US Air Force. They arrived with the members of Project Blue Book.

One of the aliens’ pancakes was given to a local judge by Simonton who vouched for his honesty and reliability. The second pancake was received by Dr. J. Allen Hynek, and the third one was handed over to the Food and Drug Administration by the Air Force. After some analysis, it was found out that the pancakes were made from completely earthy products.

Within a few days, this strange story turned from an interesting UFO encounter into a nationwide joke. The newspapers spoke of the incident in a derisive tone, but the people who had known Simonton for a long time believed him. When Dr. Hynek met Simonton for the first time, he was quite impressed by his behavior. He wrote in one of his Project Blue Book reports that Simonton knew that they would not believe him but he did not care. He simply assured that whatever he witnessed had happened in reality.

Simonton lived In the Eagle River which is surrounded by forests and lakes and is close to the Michigan border. In the following month of the incident, the area suffered a power failure and all the telephone lines were also affected. Besides, a fighter jet (B-47 bomber) crashed 60 miles from Eagle River on February 24 of the same year, and on May 2, another plane crashed near that area. The pilot in the second crash said: “I felt this weightlessness and I was hanging by my straps” just before the crash. The place had many strange UFO sightings from 1959 to 1963 but never got public attention.

The Eagle River UFO incident has been unsolved. The Air Force said that Simonton mistook a dream and considered it a reality.

The Canadian government is no stranger to the subject of UFOs, objects that today the United States government prefers to call unidentified anomalous/aerial phenomena, or UAP.

Between 1950 and 1995, the Canadian military investigated UFOs, beginning with Project Magnet on December 2, 1950, under the direction of senior radio engineer Wilbert Brockhouse Smith and developed by Transport Canada to collect data and research on unidentified flying objects. The goal was to apply any recently recovered data to modern-day technologies or engineering. At the end of the first study, Smith concluded that UFOs were ET in origin and used the manipulation of magnetism to fly the object or craft.

Shortly thereafter, on April 22, 1952, Project Second Story (also known as Project Flying Saucers and Project Theta) was established by the Defence Research Board, Canada’s military science agency.

The distinction between the two Canadian projects lies in their origins and scope. While Project Magnet was initiated and overseen by one individual, Project Second Story was a collaborative effort involving government agencies and Canadian military intelligence and was specifically tasked with handling UFO reports. Additionally, Project Second Story was funded by the Defence Research Board in Canada. In total, the committee held 6 meetings and ended in 1954. The program’s demise resulted from the government’s determination that, ultimately, the UFO phenomenon was not conducive to scientific investigation.

From a Canadian perspective, developments regarding the UAP topic have been relatively quiet for the past 70 years. That is, until Former Minister of Defense Paul Hellyer stepped forward in 2005, publicly expressing his belief that extraterrestrials are visiting Earth. Media, government officials, and Canadian civilians had mixed reactions to his statement which became a global conversation overnight. Hellyer was the first formal government official from a G7 country to step forward and speak on ETs and UFOs.

Hellyer passed away on August 8, 2021, at the age of 98. He didn’t live long enough to see how, in 2023, Canadian MP Larry Maguire would similarly come forward, writing a letter claiming that the Canadian government possesses material related to UAP.

Shortly prior to Maguire’s statement, the Canadian government established Sky Project Canada, in which the Office of the Chief Science Advisor (OCSA) was tasked with developing Canadian protocols for documenting and addressing UAP observations.

Since the release of Maguire’s initial statement on UAP, Maguire has only addressed the subject on a few occasions, which included an appearance at the Sol Foundation inaugural symposium in Palo Alto, California, in November 2023.

In a conversation with The Debrief, MP Larry Maguire recently explored his thoughts on the UAP subject, the Canadian government’s position, and his proposals for advancing the subject in Canada (the following Q&A has undergone minor editing for additional clarity).

Cassini Observations Suggest Underground Ocean on Titan

Titan, the largest moon of Saturn, harbors an internal low-density ocean of water or ammonia, according to an analysis of archival data from NASA’s Cassini mission.

Representation of Cassini’s orbits used to calculate Titan’s gravity; the colored part of the orbits shows the distance from Cassini to Titan with the smallest distance in red; the cross-section of Titan shows the moon’s different layers with the ocean in blue; Saturn with rings and ring shadows can be seen in the background.

Image credit: Britt Griswold, NASA’s Goddard Space Flight Center.

“Liquid water is one of the prerequisites for the emergence of life,” said Dr. Sander Goossens from NASA’s Goddard Space Flight Center and colleagues.

“Water is rarely liquid on the surface of a planet, but a number of moons in our Solar System, such as Titan, contain underground oceans.”

“These probably formed long ago, which raises the question of why they are not yet frozen in the cold environment far from the Sun.”

“Our study supports the explanation that ammonia extended the life of the liquid ocean in Titan. In addition, it provides insight into Titan’s deeper layers.”

NASA’s Cassini mission explored Saturn and its icy moons for more than a decade.

Among its many instruments, Cassini carried a radio science subsystem that enabled Earth-based radiometric tracking of the spacecraft by the Deep Space Network.

These data were used to determine the gravity field and interior structure of several of Saturn’s moons as well as those of Saturn itself. Cassini data were also used to determine Titan’s tidal response.

“The Cassini space mission flew around Saturn between 2005 and 2017,” the researchers said.

“To precisely measure Titan’s gravity, the spacecraft was sent close to the moon several times.”

“Cassini had to skim past Titan at exactly the right time to properly map the change in gravity.”

“This is because Titan’s deformation is due to Saturn’s tidal force, which depends on the distance between Titan and Saturn.”

“By measuring at times when Titan is close and far away from Saturn, the difference in Titan’s deformation and thus its effect on gravity was maximum.”

From precise radar measurements, the scientists calculated Cassini’s velocity and then the change in gravity and Titan’s deformation associated with it.

They carefully examined the effect of tides on Titan at each location in the spacecraft’s orbit and concluded that the deformation is smaller than previously calculated.

Numerical simulations of the moon’s deformation for different internal structures show that the most likely scenario is that the ocean has a density similar to that of water with a small proportion of ammonia.

“An underground ocean can help transport organic material from a moon’s rock core to the surface,” the authors said.

“For Titan, it was assumed that a thick ice layer between the ocean and the core made this difficult.”

“Our analysis suggests that the ice layer is possibly thinner than previously thought, making exchange of material between rock and the ocean more plausible.”

“The organic molecules that this can produce are seen as important ingredients for the emergence of life.”

De Sahara wordt beschouwd als de woestijn bij uitstek: het woord zelf betekent woestijn, dus het zeggen van "Saharawoestijn" staat gelijk aan het zeggen van "woestijn van de woestijn". Er is geen drogere plek op onze planeet, maar toch was de Sahara in het verleden een groene plek vol leven. Volgens sommige onderzoekers doorloopt de woestijn bij uitstek een cyclus die hem in de toekomst weer vruchtbaar zal maken. Laten we eens kijken hoe dit mogelijk is.

Vroeger was de Sahara vol leven, en dat zal nog steeds zo zijn: dat zegt een studie

De Sahara is de droogste plek op onze planeet: 9 miljoen vierkante kilometer groot en door de eeuwen heen het symbool geworden van de woestijn zelf, en om zeer goede redenen. Volgens een recente studie had de Sahara in het verleden echter ook een ecosysteem vol leven en zou het, belangrijker nog, weer een ecosysteem kunnen worden. Het onderzoek, gepubliceerd in Nature Communications en uitgevoerd door een team van de universiteiten van Helsinki, Birmingham en Bristol, analyseerde het klimaat van de Sahara gedurende de afgelopen 800.000 jaar. Met onverwachte resultaten.

Dankzij een reeks simulaties met een geavanceerd klimaatmodel ontdekten de onderzoekers dat de woestijn bij uitstek transformeert in een groen paradijs tijdens de zogenaamde Afrikaanse vochtige perioden, dat wil zeggen elke 21 duizend jaar. De laatste Afrikaanse vochtige periode vond plaats tussen ongeveer 14.000 en 6.000 jaar geleden: de Sahara herbergt nog steeds bewijzen van rivieren en meren, flora en fauna, in een rijk ecosysteem dat nu (bijna) volledig is verdwenen.

Dankzij de simulaties van het HadCM3B-model, gebruikt om deze resultaten te verkrijgen, ontdekten de onderzoekers een cyclus van wedergeboorte van de Sahara, maar niet alleen dat. Elke 21 duizend jaar keert de woestijn bij uitstek terug om een ​​ecosysteem te huisvesten dat rijk is aan leven, synchroon met de oscillatie van de aardas. Deze beweging controleert in feite de intensiteit van de Afrikaanse moessons, periodieke winden die op hun beurt de hoeveelheid regen bepalen die op de Sahara valt, en dus ook op de vegetatie.

Het laatste element dat verband houdt met de vochtige perioden in Afrika betreft de ijskappen. In de praktijk is het onmogelijk dat er een natte periode ontstaat als het noordelijk halfrond van de aarde een grote ijskap heeft. Deze koelen in feite de atmosfeer af, waardoor de regenval in gebieden zoals de Sahara afneemt en daardoor woestijnvorming veroorzaakt.

De invloeden van de Sahara tussen verleden en toekomst

NASA

Volgens Edward Armstrong, hoofdauteur van het onderzoek, vertegenwoordigt de cyclus van transformatie van de woestijn in savanne en bos een van de belangrijkste veranderingen in het milieu die op aarde plaatsvinden. Het belang van het gebruikte rekenmodel ligt juist in het vermogen om de Afrikaanse vochtige perioden succesvol te reproduceren en daardoor een duidelijker beeld te geven van hun cycliciteit. De cycli van 21.000 jaar hebben immers niet alleen de geografie beïnvloed, maar behoren ook tot de oorzaken van de verspreiding van onze soort uit Afrika.

Tegelijkertijd zijn dit natuurlijke veranderingen die theoretisch niet gekoppeld zijn aan recentere fenomenen zoals de stijgende temperaturen op aarde. Al is het niet uitgesloten dat het een het ander kan beïnvloeden. Hoe je het ook bekijkt, onze planeet verandert op een dynamische manier en blijft zelden hetzelfde: dit blijkt uit de vochtige periode die de Sahara opnieuw zou kunnen transformeren in een weelderige uitgestrektheid vol leven. Over een paar duizend jaar

Look! This Strange Cosmic Cloud Looks Like a Dinosaur

This striking image of CG4 was captured by a telescope instrument originally built to study dark energy.

BY KIONA SMITH

 

NOIRLab

This strange cosmic cloud is called “the hand of God,” but it looks more like a Tyrannosaurus rex to us.

The reddish aura surrounding the cloud of gas and dust called CG4 comes from hydrogen gas, heated and ionized (electrically charged) by the radiation from massive nearby stars. That powerful bombardment of radiation is probably what eroded and stretched CG4 into its distinctive shape.

Astronomers call clouds like CG4 cometary globules, because their long, dust-shrouded tails look a bit like comets, even though they form completely different ways and on drastically different scales (one cometary globule probably contains a few star systems’ worth of actual comets). This one, CG4, is an especially dense patch of gas and dust within the larger Gum Nebula, which is home to the Vela Supernova Remnant and the Vela Pulsar.

Cometary globules like CG4 are just one form of a type of cosmic cloud called a Bok Globule. These clouds of gas and dust are so dense that visible and ultraviolet light can’t pass through them, making them appear as dark shadows in telescope images (when we can see them at all). The best way to see a Bok Globule is with an infrared telescope, like the Dark Energy Camera: an instrument mounted on the Victor Blanco Telescope on a mountaintop in Chile.

Weirdly, all of the 32 cometary globules in the Gum Nebula have their heads pointed toward the center of the nebula, where the fast-spinning Vela Pulsar lurks at the heart of the Vela Supernova Remnant; the pulsar and the expanding cloud of stellar debris around it are all that’s left of a massive star that exploded in a supernova about 1 million years ago. That explosion, along with radiation and charged particles from nearby massive stars in the Gum Nebula, may have shaped CG4 and other cometary globules into their streamlined shapes.

If you’d like a sense of scale, CG4 is about 1300 light years away. Its head is about 1.5 light-years wide, and its faint tail stretches across 8 light years.

De rotstekeningen zijn uitgebreid onderzocht tijdens veldwerk in de jaren 2018 en 2019. Julien Cooper van de Macquarie University in Australië leidde toen een team archeologen in het zogenoemde Atbai Survey Project, waarin 16 nieuw ontdekte rotstekeningen uit Wadi Haifa werden bestudeerd. 

Vandaag is het een kurkdroge regio in het oosten van Soedan. Maar de tekeningen suggereren dat de omgeving er toen compleet anders uitzag. Er viel veel meer regen en het landschap zag er groen uit, weelderig groen zelfs, moet blijken uit de rotstekeningen waarop vee staat afgebeeld. 

"Het was een raadsel om vee afgebeeld te zien op de wanden van rotsen midden in de woestijn, want voor het houden van runderen is veel water nodig, en weiland. Ze zouden in de Sahara van vandaag geen kans maken", zegt Cooper in een mededeling van de universiteit. 

Volgens Cooper is de aanwezigheid van heel wat vee in de tekeningen "een van de belangrijkste bewijsstukken van een voormalige groene Sahara". Dat komt ook overeen met eerdere bevindingen van experts. 

Groene Sahara? 

Eerder archeologisch en klimatologisch veldwerk heeft al aangetoond dat alvast een deel van de huidige Sahara in Afrika er vroeger totaal anders moet hebben uitgezien tijdens de zogenoemde "Afrikaanse natte periode"

Er viel toen veel regen in de regio tijdens moessonregens in de zomer. De vochtige periode zou van ongeveer 15.000 jaar geleden tot ruwweg 5.000 jaar geleden hebben gelopen en dan langzaam zijn uitgedoofd. Er zou plaats geweest zijn voor een afwisselende Afrikaanse savanne waar ook giraffes en olifanten leefden. 

Rond 3.000 voor Christus begonnen meren en rivieren uit te drogen en verdwenen ook de grazige weiden. De mensen trokken weg in de richting van de Nijl. 

De aanwezigheid van mensen bij het vee suggereert dat de dieren gemolken werden. Er zouden herders geleefd hebben in het gebied, maar zij begonnen het rond 3.000 voor Christus moeilijker te krijgen.

"De bevolking trok weg en er waren hoogstens nog schapen of geiten. De impact op het leven moet groot geweest zijn", zegt Cooper. 

De tekeningen tonen niet enkel vee. Er zijn ook boten afgebeeld. Die hebben speciale kenmerken in deze tekeningen, en waren misschien het werk van plaatselijke Nubische Nubische stammen. 

Sahara was ooit weelderig groen, blijkt uit rotstekeningen van 4.000 jaar geleden die vee afbeelden

Unveiling the Enigmatic Secrets of Area 51 and UFOs

Area 51, nestled within the desolate stretches of the Nevada desert, has long captivated the imagination of millions around the world. Officially a remote detachment of Edwards Air Force Base, this highly classified U.S. Air Force facility is shrouded in secrecy, giving rise to numerous theories and stories about extraterrestrial activities and groundbreaking technology. Let’s delve into some of the intriguing accounts that contribute to the legendary status of Area 51.

Historical Context and Alleged Alien Encounters

The intrigue surrounding Area 51 often centers on accounts of unidentified flying objects (UFOs) and their purported connection with the U.S. government. One of the most storied events allegedly occurred on May 19, 1953, during a series of nuclear tests under the codename “Upshot-Knothole” at Yucca Flat, Nevada. Observers reported seeing a disc-shaped object descending rapidly from the sky, which then disappeared into the mountains south of Las Vegas. This incident was followed by rumors that the U.S. government swiftly assembled a team to investigate a UFO crash in the outskirts of Kingman, Arizona, approximately 175 miles south of the test site.

The Kingman UFO incident is said to involve a 40-foot diameter disc-shaped craft that was found intact, with no visible damage, and accompanied by four extraterrestrial beings. The recovered craft and beings were reportedly transported to what is now known as Area 51 for further examination and reverse engineering.

Theories of Reverse Engineering and Collaboration

Speculations suggest that Area 51’s primary purpose might extend beyond testing experimental aircraft and weaponry. It is believed to include the reverse engineering of alien technology. According to some accounts, this includes working directly with extraterrestrial beings, such as an entity named J-Rod, who allegedly assisted U.S. scientists and engineers in understanding alien technology.

Area 51’s lore also includes tales of underground facilities where extensive collaboration between humans and aliens takes place. These stories are bolstered by testimonies from individuals like Captain Bill U House, a former U.S. Air Force officer who claimed to have worked closely with an extraterrestrial being to gain insights into alien science and engineering.

Modern Myth or Hidden Truths?

As fantastical as these stories might sound, they are supported by various whistleblowers and former employees who assert the existence of alien technology at Area 51. These claims, while lacking concrete evidence and often dismissed by skeptics, fuel ongoing interest and debate regarding what truly lies within the confines of this secretive base.

Despite numerous public disclosures and declassifications of documents, the U.S. government remains largely silent about the full extent of activities at Area 51. This secrecy only amplifies the mystery and the allure of the base, making it a central figure in UFO folklore.

Area 51 continues to be an emblematic symbol of UFO conspiracy theories and a focal point for those who believe in extraterrestrial visits. Whether these beliefs are grounded in reality or are merely products of the human imagination, Area 51 undeniably holds a significant place in popular culture as a repository of the unknown and possibly the extraterrestrial. As long as the veil of secrecy remains, the theories about what really happens behind the gates of Area 51 will continue to proliferate, captivating the minds of those who seek answers to the age-old question: Are we alone in the universe?

A bloke has claimed he saw a “glowing white orb UFO” and it looked exactly like one depicted in the infamous 1300s painting of Jesus Christ's crucifixion.

According to a post on Reddit's biggest alien forum, the poster – going by the name of Kaiserschleier – was talking to his brother-in-law while in an unidentified countryside when he has his “first experience” of an encounter with a UFO.

Taking to the forum, he said: “I was chatting with my brother-in-law in the countryside when suddenly, I glanced up and spotted a glowing white orb. It swiftly shot away the moment I looked at it, hovering about 20 feet above ground, leaving behind a trail of orange flame-like glow as it moved. It moved swiftly and emitted no sound.

“I was so stunned, I jolted and said 'What the f**k is that?!' – my brother-in-law confirmed to have seen the same thing as me, saying that it looked like a flying glowing moon.”

He explained: “Despite its radiant glow, it emitted no illumination onto its surroundings. Its hues of white and orange were exceptionally vivid, yet it remained silent as it traversed in a perfectly straight trajectory, devoid of any audible disturbance even amidst the passage through the air.

“This occurrence defied any rational explanation, unlike anything I've ever encountered before. Its proximity ruled out possibilities like a comet or shooting star, as it hovered closer to the ground than the tree canopy.

“I'm left baffled by this enigmatic phenomenon, never before witnessed or heard of, and the mere fact that I bore witness to it fills me with a profound sense of awe.”

So, Daily Star reader, what do you think?

New NASA Visualization Shows Supermassive Black Hole’s Event Horizon

Thanks to a new visualization produced on a NASA supercomputer, you can plunge into the event horizon, a black hole’s point of no return.

“People often ask about this, and simulating these difficult-to-imagine processes helps me connect the mathematics of relativity to actual consequences in the real Universe,” said Dr. Jeremy Schnittman, an astrophysicist at NASA’s Goddard Space Flight Center.

“So I simulated two different scenarios, one where a camera — a stand-in for a daring astronaut — just misses the event horizon and slingshots back out, and one where it crosses the boundary, sealing its fate.”

To create the visualizations, Dr. Schnittman teamed up with Goddard Space Flight Center scientist Brian Powell and used the Discover supercomputer at the NASA Center for Climate Simulation.

They generated about 10 terabytes of data and took about 5 days running on just 0.3% of Discover’s 129,000 processors. The same feat would take more than a decade on a typical laptop.

The destination is a supermassive black hole with 4.3 million times the mass of our Sun, equivalent to the monster located at the center of our Milky Way Galaxy.

“If you have the choice, you want to fall into a supermassive black hole,” Dr. Schnittman said.

“Stellar-mass black holes, which contain up to about 30 solar masses, possess much smaller event horizons and stronger tidal forces, which can rip apart approaching objects before they get to the horizon.”

This occurs because the gravitational pull on the end of an object nearer the black hole is much stronger than that on the other end. Infalling objects stretch out like noodles, a process astrophysicists call spaghettification.

The simulated black hole’s event horizon spans about 16 million miles (25 million km), or about 17% of the distance from Earth to the Sun.

A flat, swirling cloud of hot, glowing gas called an accretion disk surrounds it and serves as a visual reference during the fall.

So do glowing structures called photon rings, which form closer to the black hole from light that has orbited it one or more times.

A backdrop of the starry sky as seen from Earth completes the scene.

As the camera approaches the black hole, reaching speeds ever closer to that of light itself, the glow from the accretion disk and background stars becomes amplified in much the same way as the sound of an oncoming racecar rises in pitch.

Their light appears brighter and whiter when looking into the direction of travel.

The movies begin with the camera located nearly 640 million km (400 million miles) away, with the black hole quickly filling the view.

Along the way, the black hole’s disk, photon rings, and the night sky become increasingly distorted — and even form multiple images as their light traverses the increasingly warped space-time.

In real time, the camera takes about 3 hours to fall to the event horizon, executing almost two complete 30-min orbits along the way. But to anyone observing from afar, it would never quite get there.

As space-time becomes ever more distorted closer to the horizon, the image of the camera would slow and then seem to freeze just shy of it. This is why astronomers originally referred to black holes as “frozen stars.”

At the event horizon, even space-time itself flows inward at the speed of light, the cosmic speed limit.

Once inside it, both the camera and the space-time in which it’s moving rush toward the black hole’s center — a one-dimensional point called a singularity, where the laws of physics as we know them cease to operate.

The NASA visualization tracks a camera as it approaches, briefly orbits, and then crosses the event horizon — the point of no return — of a supersized black hole similar in mass to the one at the center of our Galaxy.

Image credit: J. Schnittman & B. Powell, NASA’s Goddard Space Flight Center.

“Once the camera crosses the horizon, its destruction by spaghettification is just 12.8 seconds away,” Dr. Schnittman said.

From there, it’s only 128,000 km (79,500 miles) to the singularity. This final leg of the voyage is over in the blink of an eye.

In the alternative scenario, the camera orbits close to the event horizon but it never crosses over and escapes to safety.

If an astronaut flew a spacecraft on this 6-hour round trip while her colleagues on a mothership remained far from the black hole, she’d return 36 min younger than her colleagues.

That’s because time passes more slowly near a strong gravitational source and when moving near the speed of light.

“This situation can be even more extreme,” Dr. Schnittman said.

“If the black hole were rapidly rotating, like the one shown in the 2014 movie Interstellar, she would return many years younger than her shipmates.”

Krachtige zonne-explosies hebben een sterke impact op de aarde: wat zou er kunnen gebeuren?

Door Janine

De krachtige uitbarstingen die op onze moederster exploderen, hebben een sterke impact op de aarde en lijken niet te stoppen. Dit is wat er gebeurt.

Wat zijn zonnevlammen?

SPACE WEATHER PREDICTION CENTER

Een zonnevlam, zo meldt NASA, is "een intense uitbarsting van straling door het vrijkomen van magnetische energie die gepaard gaat met zonnevlekken". Dit zijn, legt de Amerikaanse ruimtevaartorganisatie uit, de grootste explosieve gebeurtenissen in ons zonnestelsel. Ze manifesteren zich als heldere gebieden op de zon die enkele minuten tot enkele uren zichtbaar zijn.

Wat ons in staat stelt om ze te detecteren is het licht, dus de fotonen, die vrijkomen en die worden gecontroleerd door optisch licht en röntgenstraling. In zonnevlammen worden de zwaarste deeltjes versneld. De afgelopen dagen zijn zonnevlammen in volle actie: X1.6 vond plaats op 3 mei, gevolgd door andere krachtige fenomenen volgens het Space Weather Prediction Center van NOAA. Elk van deze fenomenen heeft een grote impact gehad op onze planeet.

De gevolgen van krachtige zonnevlammen op aarde

Een X1.3 en een X1.2 zonnevlam barstten op 5 mei los uit de actieve groep zonnevlekken AR 3663. In beide gevallen traden radio blackouts op op onze planeet, in Japan, Australië en grote delen van China, en de effecten zouden langer kunnen duren als coronale massa uitstoot, enorme wolken van zonneplasma doordrenkt met magnetische veldlijnen, geladen deeltjes naar de aarde zouden leiden.

Hierover zijn echter geen zekere gegevens bekend. Er zijn momenteel negen clusters zonnevlekken aanwezig aan de kant van de zon die naar onze planeet is gericht, die ongeveer 150 zonnevlekken omvatten. AR 3663 is op dit moment in ieder geval het meest actief en heeft sinds 30 april meerdere M-klasse en vier X-klasse vlammen uitgezonden, waarmee hij op de tweede plaats staat van de sterkste vlammen die onze ster kan produceren.

Maar wat zijn de voorspellingen van de wetenschappers en wat kunnen we verwachten? Volgens de voorspellers zullen er meer M-klasse vlammen zijn en mogelijk nog een of meer X-klasse vlammen voordat ze buiten de baan van de aarde draaien.

Keith Strong, een zonnefysicus, schreef in een bericht op X, voorheen Twitter: “Het gebied van zonnevlekken AR3663 produceerde een X4.5 vlam, de op twee na grootste sinds het begin van zonnecyclus 25 (4,3 jaar geleden)." Hij voegde eraan toe dat de vlam een sterke black-out veroorzaakte in een groot deel van Azië, Oost-Afrika en Oost-Europa. "Als het een coronale massa uitstoot produceerde, zal deze waarschijnlijk binnen een dag of twee de aarde raken."

Geomagnetische storm op komst? Er is iets positiefs aan

SDO | Solar Dynamics Observatory NASA

Zonnevlammen gaan soms gepaard met uitbarstingen die de aarde met een paar dagen vertraging kunnen bereiken, omdat plasma zich minder snel verplaatst dan licht. Op het moment dat de coronale massa uitstoot ons bereikt, ontstaat er echter een geomagnetische storm met aanzienlijke gevolgen voor de communicatie. Op het moment dat het de magnetosfeer van de planeet raakt, ontstaan er elektrische stromen die door elektriciteitsnetwerken kunnen reizen, stroomuitval kunnen veroorzaken en satellieten, radio- en navigatiesignalen kunnen beïnvloeden.

Maar er is ook een positief aspect: de wisselwerking tussen zonnedeeltjes, de magnetosfeer en de atmosfeer van de aarde leidt tot een opvallend poollicht boven de polen van de aarde, dat alleen 's nachts zichtbaar is, wanneer er geen zonlicht is. In elk geval zullen de volgende uitbarstingen kleine gevolgen hebben, omdat AR 3663 van de baan van de aarde af draait, maar de zon zit midden in haar activiteitscyclus, haar piek vindt om de elf jaar plaats en kan ons nog meer “verrassingen” bezorgen.

I found this structure on Mars today, just wanted to share with you all, UFO Sighting News.

Date of discovery: May 9, 2024

Location of discovery: Perseverance photo 1141-NW

     It's from the newest rover images and shows a structure on top of a Mars hilltop, best view I have to say, and the opening is facing outward to see the view. We can go on denying that life existed in our solar system on other planets, or we can cherish the excitement of new proof that it exists. It's up to you. 

    Then again, maybe not knowing, keeps your world view smaller and easier for you to manage. Much more...and it may break you.

The search for life on Mars can be traced to the late 19th and early 20th centuries when Percival Lowell made extensive observations from his observatory in Flagstaff, Arizona. Inspired by Schiaparelli’s illustrations of the Martian surface (which featured linear features he called “canali”), Lowell recorded what he also believed were canals and spent many years searching for other indications of infrastructure and an advanced civilization. During the ensuing decades, observatories worldwide observed Mars closely, looking for indications of life and similarities with Earth.

However, it was not until the Space Age that the first robotic probes flew past Mars, gathering data directly from its atmosphere and taking close-up images of the surface. These revealed a planet with a thin atmosphere composed predominantly of carbon dioxide and a frigid surface that did not appear hospitable to life. However, it was the Viking 1 and 2 missions, which landed on Mars in 1976, that forever dispelled the myth of a Martian civilization. But as Fletcher told Universe Today via email, the possibility of extant life has not been completely abandoned:

“It’s my personal belief that it is unlikely we will find evidence of extant (current) life on Mars, as opposed to evidence of past life on Mars. If we were to find extant life on Mars that could be proven to be endemic to Mars and not contamination from Earth, some think it might be found underground in lava tubes, for example, and some think the ice caps or any possible source of liquid water might be suitable places.”

Ironically, it was the same missions that discredited the notion of there being life on Mars that revealed evidence that water once flowed on its surface. Thanks to the many orbiter, lander, and rover missions sent to Mars since the turn of the century, scientists theorize that this period coincided with the Noachian Era (ca. 4.1 – 3.7 billion years ago). According to the most recent fossilized evidence, it was also during this period that life first appeared on Earth (in the form of single-celled bacteria).

Our current astrobiology efforts on behalf of NASA and other space agencies are focused on Mars precisely for this reason: to determine if life emerged on Mars billions of years ago and whether or not it co-evolved with life on Earth. This includes the proposed Mars Sample Return (MSR) mission that will retrieve the drill samples obtained by the Perseverance rover in the Jezero Crater and return them to Earth for analysis. In addition, NASA and China plan to send crewed missions to Mars by 2040 and 2033 (respectively), including astrobiology studies.

These activities could threaten the very abodes where evidence of past life could be found or (worse) still exists. “Human activities might threaten sites like this in part due to possible microbial contamination,” said Fletcher. “Evidence of life (past and extant) also has greater scientific value when in its palaeoenvironmental context, so any human activities that might damage the evidence of life and/or its surrounding environmental context pose a risk. This could be something innocuous, like debris falling in the wrong spot, or something more serious, like driving over possibly significant outcrops with a rover.”

Conservation measures must be developed and implemented before additional missions are sent to Mars. Given humanity’s impact on Earth’s natural environment and our attempts to mitigate this through conservation efforts. In particular, there have been numerous cases where scientific studies were conducted without regard for the heritage value of the site and where damage was done because of a lack of proper measures. These lessons, says Fletcher, could inform future scientific efforts on Mars:

“It’s important that we learn from what has been considered “damaging” on Earth and take this into consideration when exploring Mars. If a site is damaged beyond being able to be studied in the future, then we limit what can actually be learned from a site. When considering Mars missions cost billions of dollars and are to meet specific scientific goals, limiting the information being learned from a site is incredibly detrimental. My recommendations are that of my paper: interdisciplinary cooperation, drawing on experience and knowledge from Earth, creating norms and a code of practice (part of my PhD work), and working towards creating legislation for these issues.”

The need for exogeoconservation is paramount at this juncture. In addition to Mars, multiple astrobiology missions will travel to the outer Solar System this decade to search for evidence of life on icy moons like Europa, Ganymede, Titan, and Enceladus. This includes the ESA’s JUpiter ICy moons Explorer (JUICE) mission, currently en route to Ganymede, and NASA’s Europa Clipper and Dragonfly missions that will launch for Europa and Titan in October 2024 and 2028 (respectively). Therefore, the ability to search for extant or past life without damaging its natural environment is an ethical and scientific necessity.

“I hope this paper is very much a starting point for anyone working in Mars science and exploration, as well as anyone thinking about space policy and exogeoconservation,” said Fletcher. “My goal was to start drawing attention to these issues, and that way start a generation of researchers and practitioners focused on exogeoconservation of Mars.”
