Artist’s rendering of the interstellar object Oumuamua

Last summer, the Pentagon believe the All Domains Anomaly Resolution Office (AARO), tasked with investigating unidentified aerial phenomena. Its director, Sean Kirkpatrick, held in a report published on March 7, elaborated together with Harvard University astronomer Avi Loeb, that some of the objects, which seem to defy all the laws of physics, could be alien probes.

In their non-peer-reviewed article, Kirkpatrick and Loeb echoed the discovery in 2017 of the interstellar object Oumuamua that generated debates in the scientific community, leaving everyone perplexed by the lack of conclusive evidence about its origin and nature.
Oumuamua, an alien mothership?
Unlike the asteroids or comets of the Solar System, Oumuamua had an extremely flat shape and was moving away from the Sun due to radiation pressure without leaving behind a tail of gas and dust, typical of comets, which gave rise to the possibility of that it was an artificial object, something that scientists could neither confirm nor deny with 100% certainty.
Its behavior turned out to be similar to that of another object, detected in space three years later, which, in turn, was artificial for sure, in the case of the Centaur booster rocket of the Surveyor 2 mission of the last century, baptized as 2020 SO.

In the opinion of Kirkpatrick and Loeb, Oumuamua could be an alien mother ship that sent small probes to Earth for scientific exploration, similar to NASA’s exploratory missions. In this sense, they remembered the collision with Earth of the interstellar meteor IM2, one meter in diameter, on March 9, 2017, six months before the closest Oumuamua pass on Earth.
“Surprisingly, IM2 had a velocity relative to the Sun at great distances and a heliocentric semi-major axis identical to that of Oumuamua. But the inclination of IM2’s orbital plane around the Sun was completely different from that of Oumuamua, implying that the two objects are not related,” Kirkpatrick and Loeb wrote.
“Nonetheless, the coincidences between some orbital parameters of Oumuamua and IM2 inspire us to contemplate the possibility that an artificial interstellar object could potentially be a mothership that releases many small probes during its near-Earth passage,” they concluded.

These “dandelion seeds” could be separated from the main ship by the gravitational force of the Sun, passing through the Earth’s atmosphere until reaching the surface. The report authors believe they could also reach other planets in the Solar System for exploration, possibly using starlight to charge their batteries and liquid water, which could exist on the surfaces of rocky planets like Earth, as fuel. .
“Like biological seeds, they could also use raw materials from the planet’s surface as nutrients for self-replication or simply for scientific exploration,” they wrote.
Interest “out of nowhere” from the Pentagon
just interviewed by PoliticoLoeb acknowledged that there is no evidence to support the idea that unknown flying objects are extraterrestrial probes, noting that he also has no access to classified information from authorities.
At the same time, he drew attention to the fact that Kirkpatrick came to him “out of the blue”, suggesting that “there is something out there they don’t understand and scientists could potentially help”.
