UFO Sightings: Pentagon’s New Portal Encourages Whistleblowers and Government Insiders

UFO Sightings: Pentagon’s New Portal Encourages Whistleblowers and Government Insiders

UFO report

In a world buzzing with tales of mysterious lights and unidentified aircraft, the Pentagon is stepping into the limelight with an unexpected initiative. If you’ve ever Googled “UFO sightings” out of pure curiosity or genuine belief, this latest move by the U.S. government will undoubtedly pique your interest.

UFO sightings have long captured the imagination of enthusiasts and skeptics alike. From grainy videos on YouTube to firsthand accounts from pilots, the mystery surrounding unidentified aerial phenomena (UAP) remains largely unsolved. Now, in a groundbreaking move, the Pentagon is extending an invitation to those in the know.

Pentagon’s UAP Reporting Website:

Late last October, amidst swirling speculations and decades of reported sightings, the Pentagon unveiled its official UFO reporting platform (link: https://www.aaro.mil/AARO-Reporting-Information/). Designed for U.S. government insiders, the website seeks to gather reliable information regarding UAP encounters and any covert programs related to them.

A Special Call for Whistleblowers:

Dr. Sean Kirkpatrick, spearheading the All-domain Anomaly Resolution Office (AARO), emphasized the platform’s focus. “We strongly encourage any current or former U.S. government employees, military or civilian, or contractors with firsthand UAP knowledge to come forward,” he stated. This intriguing call-out places an emphasis on the importance of credible sources, suggesting that the government is keen on sifting fact from fiction.

Privacy, Confidentiality, and Accountability:

The AARO assures that all reports will remain confidential. However, in an age where misinformation can spread like wildfire, the Pentagon is taking no chances. A stern warning accompanies the reporting form, reminding users of the severe consequences of falsifying information. With potential repercussions like imprisonment or termination of federal service, the message is clear: only genuine, verifiable information is welcome.

A Spotlight on Whistleblower David Grusch:

Among the many names associated with UFO sightings, David Grusch stands out. Claiming intimate knowledge of hidden government UFO projects, Grusch has caught the attention of UAP enthusiasts worldwide. Kirkpatrick, however, offered a fresh perspective. Despite multiple outreach attempts, Grusch has yet to discuss his claims with the AARO. Yet, the very mention of Grusch’s name indicates the Pentagon’s proactive approach in seeking the truth.

Deciphering the Mysteries of the Sky:

Beyond seeking whistleblower accounts, the AARO is diligently working to distinguish genuine UAP sightings from identifiable objects. Efforts are underway to understand how common objects appear on military equipment sensors, aiming to minimize misidentifications. Kirkpatrick explained, “We want to reduce the number of UAP reports that are merely balloons or drones.”

Why Trust the AARO? 

In an age of skepticism, trust is hard-earned. So, why should insiders confide in the AARO? Kirkpatrick’s answer is straightforward: “It’s in law that we are the authorized reporting authority.” Coupled with the Whistleblower Act’s protection and the promise of anonymity, the AARO seems poised to become a pivotal entity in the world of UFO sightings.

Conclusion:

As tales of mysterious lights continue to fill the skies and online forums, the Pentagon’s initiative is a beacon for those seeking answers. With a focus on veracity and a commitment to uncovering the truth, this new portal may just hold the key to some of the world’s most enigmatic mysteries.

“The truth is out there; but, the establishment exists to destroy it. What is the point of seeking truth when truth is annihilated in the efforts to find it?”

 – Suzy Kassem

The skies have always held mysteries, and it seems the Pentagon is now actively joining the quest to decode them.

Has the mystery of how the moon formed finally been solved? Our lunar satellite was propelled into orbit IMMEDIATELY after a giant impact between Earth and a Mars-sized planet 4.5 billion years ago, study claims

Has the mystery of how the moon formed finally been solved? Our lunar satellite was propelled into orbit IMMEDIATELY after a giant impact between Earth and a Mars-sized planet 4.5 billion years ago, study claims

  • Scientists suspect moon was created when a planet called Theia struck Earth
  • But the nature of collision and what happened after has been subject to debate
  • Some believe collision created debris which coalesced into the moon over time
  • In a new study, researchers ran the most detailed supercomputer simulations yet
  • Findings suggest the moon was placed into orbit around Earth immediately 

It's a question that has puzzled scientists for hundreds of years – how exactly did our moon form?

Since the 1970s, astronomers have suspected that the moon was created when a giant protoplanet called Theia struck Earth.

However, the nature of this collision and what happened immediately after has been subject to debate.

Some scientists believe that the collision created a vast cloud of debris, which coalesced into the moon over time.

However, in a new study, researchers from the University of Durham claim that the giant impact immediately placed the moon into orbit around Earth.

Vincent Eke, co-author of the study, said: 'This formation route could help explain the similarity in isotopic composition between the lunar rocks returned by the Apollo astronauts and Earth's mantle.

'There may also be observable consequences for the thickness of the lunar crust, which would allow us to pin down further the type of collision that took place.'

The Moon theories 

Astronomers have long suspected that the moon was created when a giant protoplanet called Theia struck the newly formed Earth - a theory first put forward in the 1970s.

It says the huge collision created a vast cloud of debris, which coalesced into the moon.

However, until now, astronomers have not been able to explain how this left the moon and Earth chemically identical.

Later, two hypotheses arose that could explain why the moon is Earth's chemical clone, but they predict radically different masses for Theia.

In one scenario, two half-Earths merged to form the Earth-moon system.

But the second hypothesis suggests Theia was a small, high-velocity projectile that smacked into a large and fast-spinning young Earth.

About 4.45 billion years ago, 150 million years after the solar system formed, Earth was hit by a Mars-sized object called Theia.

The collision created the moon, but debate has raged about exactly what happened during this event - and the question of why the moon and Earth are so similar in their composition has remained a mystery.

In the study, the researchers set out to explain the Moon's origin story once and for all.

The team used the SWIFT open-source simulation code, run on the DiRAC Memory Intensive service ('COSMA'), to create the most detailed supercomputer simulations yet.

This allowed them to simulate hundreds of different impacts, varying the angle and speed of the collision as well as the masses and spins of the two colliding bodies.

While previous studies have used lower-resolution simulations, the extra computational power revealed important new aspects.

For example, only the high-resolution simulations produced the Moon-like satellite, and the extra detail showed how its outer layers were richer in material originating from Earth.

If much of the Moon formed immediately following the giant impact, this could mean that less material became molten during formation than previously thought, according to the researchers.

Depending on how this molten rock solidified, these theories should predict different internal structures for the Moon.

The simulations also revealed that even when a satellite passes so close to the Earth that it might be expected to be torn apart by tidal forces from Earth's gravity, the satellite can not only survive, but also be pushed into a wider, safer orbit.

Jacob Kegerreis, who led the study, said: 'This opens up a whole new range of possible starting places for the Moon's evolution.

'We went into this project not knowing exactly what the outcomes of these very high-resolution simulations would be.

So, on top of the big eye-opener that standard resolutions can give you wrong answers, it was extra exciting that the new results could include a tantalisingly Moon-like satellite in orbit.'

The researchers hope the findings will encourage further research into the Moon's composition and internal structure.

'The many upcoming lunar missions should reveal new clues about what kind of giant impact led to the Moon, which in turn will tell us about the history of Earth itself,' the team concluded.

THEIA: AN ANCIENT PROTO-PLANET THAT MAY HAVE MERGED WITH THE YOUNG EARTH TO FORM THE MOOON

About 4.45 billion years ago, 150 million years after the solar system formed, Earth was hit by a Mars-size object called Theia.

The collision created the moon, but debate has raged exactly what happened during this event - and a mystery has persisted on why the moon and Earth are so similar in their composition.

The impact of Theia with Earth was so violent, the resulting debris cloud mixed thoroughly before settling down and forming the moon.

This cloud would have been composed of some Earth material, explaining the similarity between Earth and the moon, and other material.

The colliding body is sometimes called Theia, after the mythical Greek Titan who was the mother of Selene, the goddess of the Moon.

But one mystery has persisted, revealed by rocks the Apollo astronauts brought back from the moon - why are the moon and Earth so similar in their composition?

Several different theories have emerged over the years to explain the similar fingerprints of Earth and the moon.

Perhaps the impact created a huge cloud of debris that mixed thoroughly with the Earth and then later condensed to form the moon.

Or Theia could have, coincidentally, been isotopically similar to young Earth.

A third possibility is that the moon formed from Earthen materials, rather than from Theia, although this would have been a very unusual type of impact.

Two Fragments of Protoplanet Theia Lie Deep within Earth, Geoscientists Say

Two Fragments of Protoplanet Theia Lie Deep within Earth, Geoscientists Say

A giant collision between the ancient protoplanet Theia and the proto-Earth about 4.5 billion years ago may have formed Earth’s Moon as well as two continent-sized regions — formally known as large low-velocity provinces — within Earth’s mantle, according to a research team led by Caltech scientists.

Yuan et al. suggest that LLVPs are remnants of the ancient protoplanet Theia that violently collided with Earth billions of years ago in the same giant impact that created our Moon. Image credit: Hernán Cañellas.

Yuan et al. suggest that LLVPs are remnants of the ancient protoplanet Theia that violently collided with Earth billions of years ago in the same giant impact that created our Moon.

In the 1980s, scientists discovered two continent-sized blobs of unusual material deep near the center of the Earth: one beneath the African continent and one beneath the Pacific Ocean.

Each blob is twice the size of the Moon and likely composed of different proportions of elements than the mantle surrounding it.

Where did these strange blobs — formally known as large low-velocity provinces (LLVPs) — come from?

“Terrestrial planet formation concludes with a number of giant impacts among Moon- and Mars-sized planetary embryos,” said Caltech researcher Qian Yuan and colleagues.

“The well-studied giant-impact scenario involves a protoplanet, Theia, colliding with proto-Earth.”

In the study, the authors used computer simulations to propose an explanation for LLVPs.

The material in these regions has been suggested to be between 2.0 and 3.5% denser than the surrounding mantle.

The simulations show that LLVPs may represent buried relics of Theia mantle material that was preserved in proto-Earth’s mantle after the Moon-forming giant impact.

These Theia relics are proposed to have been tens of kilometers across, and the authors suggest that they sunk to the lower region of the mantle and accumulated to form dense blobs above the Earth’s core.

“A logical consequence of the idea that the LLVPs are remnants of Theia is that they are very ancient,” said Dr. Paul Asimow, also of Caltech.

“It makes sense, therefore, to investigate next what consequences they had for Earth’s earliest evolution, such as the onset of subduction before conditions were suitable for modern-style plate tectonics, the formation of the first continents, and the origin of the very oldest surviving terrestrial minerals.”

“Our findings challenge the traditional notion that the giant impact led to the homogenization of the early Earth,” said Professor Hongping Deng, a researcher at the Shanghai Astronomical Observatory.

“Instead, the Moon-forming giant impact appears to be the origin of the early mantle’s heterogeneity and marks the starting point for the Earth’s geological evolution over the course of 4.5 billion years.”

“The Moon appears to have materials within it representative of both the pre-impact Earth and Theia, but it was thought that any remnants of Theia in the Earth would have been ‘erased’ and homogenized by billions of years of dynamics (e.g., mantle convection) within the Earth,” said Arizona State University’s Professor Steven Desch.

“This is the first study to make the case that distinct ‘pieces’ of Theia still reside within the Earth, at its core-mantle boundary.”

“It appears that Earth’s blobs are remnants of a planetary collision that formed our Moon,” said Arizona State University’s Professor Ed Garnero.

“In other words, the massive blobs currently inside Earth, deep beneath our feet, are extraterrestrial. Earth not only has ‘blobs,’ Earth has extraterrestrial blobs!”

“Through precise analysis of a wider range of rock samples, combined with more refined giant impact models and Earth evolution models, we can infer the material composition and orbital dynamics of the primordial Earth, Gaia, and Theia,” Dr. Yuan said.

“This allows us to constrain the entire history of the formation of the inner Solar System.”

“This research even provides inspiration for understanding the formation and habitability of exoplanets beyond our Solar System,” Professor Deng said.

The study was published in the journal Nature.

Woman Abducted by Reptilian Alien

Woman Abducted by Reptilian Alien

In the quaint town of Hove, England, 2008, the eerie silence of the night was pierced by an incident that might sound like the stuff of science fiction but was claimed as a lived experience by 20-year-old Charmaine D’Rozario-Saytch. This experience raises thought-provoking questions about our world and our place in the universe.

Charmaine’s story begins like any other night, with her deep in sleep, nestled comfortably in her bed. But as the night progressed, she encountered what she describes as a chilling sight – a reptilian humanoid figure looming over her. This wasn’t a figment of her imagination nor a dream. It was her reality.

She recounts being led to an underground cave, surrounded by a group of these reptilian beings. What followed was an extraordinary transformation. Charmaine claims she underwent a physical metamorphosis, watching in bewilderment and astonishment as her smooth skin turned to scales, and she grew a tail, changing from a human into a reptilian form. The very essence of her human identity seemingly altered in those moments.

But the story doesn’t end here. Charmaine asserts that her abductors revealed a startling piece of information: humans might be the result of extraterrestrial genetic manipulation. Not all, but specific groups, throughout our history, have been visited and genetically altered by different extraterrestrial races. If this assertion holds any weight, it leads us to wonder, are we truly alone in this vast universe?

Linda Moulton Howe, a noted investigator in the realm of unexplained phenomena, believes the presence of these alien entities might be tied to territorial conflicts among different extraterrestrial civilizations. These conflicts might have repercussions that impact not just these advanced beings but also the very life they’ve supposedly created or manipulated.

The very nature of these stories and theories challenges our preconceived notions about religion and ancient prophecies. Ancient texts from various religious traditions speak of divine figures returning to Earth. Could these be misinterpretations or signs pointing towards the return of extraterrestrial entities? Giorgio Tsoukalos, a prominent figure in the study of ancient astronauts, posits that these promises of return might not be of divine nature, but extraterrestrial.

As we stand at the cusp of possibly one of the most transformative eras in human history, the question that looms large is whether we’re prepared for the potential revelation of our cosmic neighbors. Will they emerge from the shadows, or are they just figments of our collective imaginations, fueled by our innate desire to not be alone in this vast expanse of the universe?

Gegevens verzameld door NASAJuno’s missie suggereert dat het zoute verleden mogelijk aan de oppervlakte komt JupiterDe grootste maan.

NASA’s Juno-missie ontdekte minerale zouten en organische verbindingen op het oppervlak van Jupiters maan Ganymede. Gegevens voor deze ontdekking werden verzameld door de Jovian InfraRed Auroral Mapper (JIRAM) spectrometer aan boord van het ruimtevaartuig tijdens een vlucht langs de ijzige maan. De resultaten, die wetenschappers zouden kunnen helpen de oorsprong van Ganymede en de samenstelling van zijn diepe oceanen beter te begrijpen, werden op 30 oktober in het tijdschrift gepubliceerd. Natuur astronomie.

Ganymedes, groter dan de planeet Mercurius, is de grootste manen van Jupiter en is lange tijd van groot belang geweest voor wetenschappers vanwege de enorme binnenoceaan van water verborgen onder de ijskoude korst. Eerdere spectroscopische waarnemingen door NASA’s Galileo-ruimtevaartuig, de Hubble-ruimtetelescoop en de Very Large Telescope van het European Southern Observatory hebben de aanwezigheid van zouten en organische materialen aangetoond, maar de ruimtelijke resolutie van die waarnemingen was te laag om vast te stellen.

Op 7 juni 2021 kwam NASA’s Juno-ruimtevaartuig dichter bij Jupiters met ijs bedekte maan Ganymede dan enig ruimtevaartuig in meer dan twintig jaar. Minder dan een dag later maakte Juno zijn 34ste scheervlucht langs Jupiter. Deze animatie biedt een ‘ruimtevaartuigkapitein’-weergave van elke vlucht. Voor beide werelden werden JunoCam-beelden orthografisch geprojecteerd op een digitale bol en gebruikt om vluchtanimaties te maken. Er zijn kunstmatige frames toegevoegd om benaderings- en vertrekbeelden van zowel Ganymede als Jupiter te bieden.

Juno’s nauwe benadering en de resultaten ervan

Op 7 juni 2021 vloog Juno over Ganymede (zie video hierboven) op een hoogte van minstens 650 mijl (1.046 kilometer). Kort na het tijdstip van de dichtste nadering maakte het JIRAM-instrument infraroodbeelden en infraroodspectra (in wezen chemische vingerafdrukken van materialen, gebaseerd op de manier waarop ze licht reflecteren) van het oppervlak van de maan. JIRAM, gebouwd door de Italiaanse ruimtevaartorganisatie Agenzia Spaziale Italiana, is ontworpen om infrarood licht (onzichtbaar voor het blote oog) op te vangen dat diep uit Jupiter komt, om de weerlaag te onderzoeken tot een diepte van 30 tot 45 mijl (50 tot 70 mijl). kilometer) hieronder. Gasreuzenwolken. Maar het instrument is ook gebruikt om inzicht te geven in de topografie van de manen Io, Europa, Ganymede en Callisto (gezamenlijk bekend als Satelliet). Manen van Galilea Voor hun ontdekker Galileo).

Eerdere modellen van het magnetische veld van Ganymedes hebben vastgesteld dat het equatoriale gebied van de maan, tot ongeveer 40 graden noorderbreedte, beschermd is tegen energetische elektronen- en zware ionenbombardementen veroorzaakt door Het helse magnetische veld van Jupiter. Het is bekend dat de aanwezigheid van deze deeltjesstromen een negatieve invloed heeft op zouten en organisch materiaal.

Tijdens de vlucht van juni 2021 besloeg JIRAM een smal bereik van breedtegraden (10°N tot 30°N) en een groter bereik van lengtegraden (35°O tot 40°O) op het naar Jupiter gerichte halfrond.

“We vonden de grootste overvloed aan zouten en organische materialen in Donker en helder terrein “Op breedtegraden waar het magnetische veld beschermt”, zegt hoofdonderzoeker Scott Bolton van de Juno-missie van het Southwest Research Institute in San Antonio. “Dit suggereert dat we de overblijfselen zien van een diepe oceaanpekel die de oppervlakte van deze bevroren wereld heeft bereikt.”

Ganymedes is niet de enige ondergrondse wereld waar Juno doorheen ging. De maan Europa, waarvan men denkt dat deze een oceaan onder zijn ijskoude korst heeft, kwam ook onder de aandacht van Juno, eerst in oktober 2021 (zie afbeelding hierboven) en vervolgens in september 2022. En nu krijgt Io de flyby-behandeling. De volgende nadering van deze met vulkanen gevulde wereld is gepland voor 30 december, wanneer het ruimtevaartuig een bereik zal bereiken van binnen 932 mijl (1.500 kilometer) van het oppervlak van Io.

In een nieuwe verkenning heeft Juno, een sonde van de NASA, een belangrijke ontdekking gedaan door mineralen en organische verbindingen op het oppervlak van de grootste maan van Jupiter en de grootste in ons zonnestelsel, Ganymedes, te observeren.

Deze gegevens werden verzameld tijdens een scheervlucht van de sonde dicht bij de bevroren maan en onthulden de aanwezigheid van ammoniumzouten, gehydrateerd natriumchloride, natriumbicarbonaat en mogelijke alifatische aldehyden, wat suggereert dat Ganymedes deze materialen tijdens zijn vorming heeft kunnen accumuleren. Deze ontdekking biedt waardevolle inzichten in de oorsprong van de maan en de samenstelling van zijn diepe oceaan.

Informatie verzameld door Juno onthulde ook dat gebieden beschermd door het magnetische veld van Jupiter de hoogste concentraties van zouten en organische verbindingen vertoonden. Deze bevinding draagt bij aan het begrip van de processen die Ganymedes in de loop van de tijd hebben gevormd en aan mogelijke oceanische omgevingen op andere hemellichamen.

Ganymedes is de grootste maan van Jupiter en staat bekend om het herbergen van een intern oceaan onder zijn bevroren korst, wat het tot een interessant onderzoeksobject maakt voor wetenschappers.

Study: Asteroid Impact-Generated Dust Played Key Role in Dinosaur-Killing Mass Extinction

Asteroid Impact-Generated Dust Played Key Role in Dinosaur-Killing Mass Extinction

About 66 million years ago, a massive asteroid crashed into Earth near the site of the small town of Chicxulub in what is now Mexico. The impact eradicated roughly 75% of the animal and plant species on Earth, including whole groups like non-avian dinosaurs and ammonites. Fine silicate dust from pulverized rock generated by the impact played a dominant role in global climate cooling and the disruption of photosynthesis following the event, according to new research.

This painting depicts an asteroid slamming into tropical, shallow seas of the sulfur-rich Yucatan Peninsula in what is today southeast Mexico. The aftermath of this immense asteroid collision, which occurred approximately 65 million years ago, is believed to have caused the extinction of the dinosaurs and many other species on Earth. Shown in this painting are pterodactyls, flying reptiles with wingspans of up to 50 feet, gliding above low tropical clouds. Image credit: Donald E. Davis / NASA.

The Chicxulub impact has long been thought to have triggered a global winter 66 million years ago, which led to the demise of the dinosaurs and around 75% of species on Earth.

However, what effect the various types of debris ejected from the crater had on the climate is debated, and exactly what caused the mass extinction remains unclear.

Previous research has suggested that sulfur released during the impact and soot from post-impact wildfires constituted the main drivers of an impact winter, but the size of silicate dust particles ejected into the atmosphere has not been considered to be a major contributor.

“The Chicxulub asteroid impact event 66 million years ago showcases a unique opportunity to examine the rate, magnitude and mechanisms of extreme and abrupt climate change in Earth’s history,” said Dr. Cem Berk Senel, a researcher at the Royal Observatory of Belgium and Vrije Universiteit Brussel, and his colleagues.

“The 45-60° inclined impact of a 10- to 15-km-sized carbonaceous chondrite on the Yucatán Peninsula in Mexico triggered a chain reaction of events ultimately responsible for the end-Cretaceous mass extinction and the demise of 75% of species, including the iconic non-avian dinosaurs.”

“Yet the climatic consequences of the various debris injected into the atmosphere following the Chicxulub impact remain unclear, and the exact killing mechanisms of the mass extinction remain poorly constrained.”

To evaluate the roles of sulfur, soot and silicate dust on the post-impact climate, Dr. Senel and co-authors produced paleoclimate simulations based on an analysis of fine-grained material emplaced at a well-preserved impact deposit from a site in North Dakota, the United States.

They found that the size distribution of silicate debris (approximately 0.8-8 micrometers) revealed a larger contribution of fine dust than previously appreciated.

They inputted the measured size distribution into a climate model and estimated that such fine dust could have remained in the atmosphere for up to 15 years after the event, contributing to global cooling the Earth’s surface by as much as 15 degrees Celsius.

They suggest that dust-induced changes in solar radiation may also have shut down photosynthesis for almost two years post-impact.

“Our simulations of the atmospheric injection of such a plume of micrometer-sized silicate dust suggest a long atmospheric lifetime of 15 years, contributing to a global-average surface temperature falling by as much as 15 degrees Celsius,” the authors said.

“Simulated changes in photosynthetic active solar radiation support a dust-induced photosynthetic shut-down for almost 2 years post-impact.”

“We suggest that, together with additional cooling contributions from soot and sulfur, this is consistent with the catastrophic collapse of primary productivity in the aftermath of the Chicxulub impact.”

The results appear in the journal Nature Geoscience.
