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.
