Scientists have learned more about ‘Oumuamua, the hunk of matter that is the first known interstellar object to ever be detected by scientists within the boundary of the solar system. Specifically, observations performed by researchers using the Spitzer Space Telescope and published in The Astronomical Journal have determined that prior observations likely established too generous an upper boundary on how large it could be.

On October 19, 2017, a strange object from outside the Solar System whizzed by the Earth, exciting scientists and non-scientists alike. Immediately, some people speculated that this interstellar visitor could be an alien spacecraft. But we’re here to report that, despite a recent paper, there’s no reason to think ‘Oumuamua is an alien ship, yet.
Life may exist elsewhere in the Milky Way galaxy, though try as they might, scientists have yet to detect any sign of it. Part of the problem has to do with the size of space; finding traces of organic substances or the waste signatures of alien megastructures isn’t easy at such cosmic distances. Fortunately, there’s the possibility that alien life will come to us in the form of interstellar objects.
Late last year, astronomers detected the first known interstellar asteroid, dubbed 'Oumuamua. New research suggests these exotic objects are more abundant than we thought, an observation that boosts the panspermia hypothesis - the idea that asteroids seeded life on Earth. At the same time, the presence of so many foreign objects in our Solar System could also change the way we search for extraterrestrial life.
On October 19, 2017, astronomers witnessed the first known interstellar asteroid - a bizarre, cigar-shaped rock that, just as quickly as it entered into our Solar System, exited in a hurry. Not satisfied that 'Oumuamua, as it's been named, is just an odd asteroid, astronomers from Breakthrough Listen recently tuned their Green Bank telescope into the object to see if it's an alien spaceship or some kind of probe. The preliminary results are now in and - brace yourself - it's still a rock.
