A Pentagon research institute claims that a small probe sent by aliens may be monitoring the earth

Scientists from the U.S. Department of Defense and Harvard University have announced that aliens may be monitoring Earth by sending small surveillance probes into the solar system.

The All-domain Anomaly Resolution Office (AARO), jointly established by Harvard University astronomer Avi Loeb and the U.S. Department of Defense in July 2022, is an unidentified flying object (UFO) and land, sea, and air・An organization that investigates unidentified aeronautical phenomena and unidentified abnormal phenomena that occur in space. Sean Kirkpatrick, director of this AARO, has released a draft called `` PHYSICAL CONSTRAINTS ON UNIDENTIFIED AERIAL PHENOMENA ''. Among them, Mr. Loeb and Mr. Kirkpatrick point out that ``a spacecraft to monitor the solar system from outside the earth may send a small probe.'' Although this document is not an official document of the Department of Defense, it was created by a joint project with the Department of Defense.

Mr. Loeb is an astronomer known for his research paper on ' Oumuamua ', an interstellar object that flew from outside the solar system. Some astronomers, including Loeb, believe that 'Oumuamua's 10:1 length-to-width ratio is unusual for asteroids and comets in the Solar System, suggesting that 'Oumuamua's surface density is high and rocks and Since it was thought to be made of metal, it was proposed that 'Isn't it a spaceship used by intelligent life forms?'

``From the Oumuamua incident, we began to consider the possibility that the observed interstellar objects were spacecraft that ejected many small probes on their way to Earth,'' Loeb said. I told Live Science of the media. Mr. Loeb also said, 'This small probe is like a dandelion seed and can be separated from the mother ship by the tidal power of the sun and the maneuverability (of the probe).'

Loeb and Kirkpatrick are investigating unidentified anomalous phenomena identified in known physics. Both are mysterious celestial bodies that move between stars like Oumuamua are `` spacecraft that aliens use to monitor the solar system '', and debris emitted by celestial bodies like Oumuamua are ``Aliens monitor the earth It points out the possibility that it is a small probe that was sent to do so. It also points out that this kind of small probe may fly to Earth without being detected by astronomers.

Loeb et al.'s research team said, 'A technological 'dandelion seed' (small probe) with a large surface-to-mass ratio like a parachute slows down in the Earth's atmosphere and burns away. and may take surveillance missions after reaching the surface.'

The research team said, ``(Aliens) will want to explore rocky planets with atmospheres in the solar system,'' pointing out that Venus, Earth, and Mars would be attractive exploration candidates for aliens. I also speculate that the aliens who built the spacecraft would not need to board the mothership and would be unlikely to be able to communicate with the spacecraft.

Furthermore, the research team points out that alien civilizations may no longer exist. This is because most of the stars in our galaxy were formed billions of years before our sun. Loeb said that intelligent life may have built probes before the earth was born, saying, ``Even if intelligent life is no longer alive, it would be impossible to examine the probe. It's a necessary act to check what alien civilizations have accumulated over time.'

Regarding the Oumuamua spacecraft theory, a paper published in ``Nature Astronomy'' in 2019 stated, ``The idea that Oumuamua was intentionally sent to Earth is ``provocative'' and ``unfounded.'' Denied the ship theory. In a letter published in Astronomy & Astrophysics in 2021, ``Given the cosmological timescales required for interstellar travel, 'Oumuamua is unlikely to be a spacecraft sent by an extraterrestrial civilization, and is an unusual form that happened to wander into the solar system. It is likely that the rocks of In addition, another paper just published in March 2023 denies the theory of the Oumuamua spacecraft, stating that 'Oumuamua's strange movements are likely due to hydrogen emissions.'
