First it was an asteroid, then it was a comet, now it’s something else. Remember that interstellar object, Oumuamua, the oblong shaped mas that tumbled through our solar system at incredible speed? Now some scientists at the Harvard Smithsonian Centre for Astrophysics are saying that it is possibly something else entirely.
Oumuamua might be artificial and could also possibly be something similar to a solar sail.
Although NASA hasn’t commented on the new study, they did observe the object unexpectedly increase speed and change trajectory as it passed through our solar system earlier this year.
