A mysterious cigar-shaped object spotted tumbling through our solar system last year may have been an alien spacecraft sent to investigate Earth, astronomers from Harvard University have suggested.
The object, nicknamed 'Oumuamua, meaning "a messenger that reaches out from the distant past" in Hawaiian, was first discovered in October 2017 by the Pan-STARRS 1 telescope in Hawaii.
The theory is based on the object's "excess acceleration," or its unexpected boost in speed as it traveled through and ultimately out of our solar system in January 2018.
"Considering an artificial origin, one possibility is that 'Oumuamua is a light sail, floating in interstellar space as a debris from an advanced technological equipment," wrote the paper's authors, suggesting that the object could be propelled by solar radiation.
At first, astronomers thought the rapidly moving faint light was a regular comet or an asteroid that had originated in our solar system. Comets, in particular, are known to speed-up due to a process known as "outgassing," in which the sun heats up the surface of the icy comet, releasing melted gas. But 'Oumuamua didn't have a "coma," the atmosphere and dust that surrounds comets as they melt.

I could have sworn the probe theory was put forth quite some time ago? Deja vu, or Mandela Effect
If it's a probe, it's absolutely epic. To us anyway, that would be a massive thing for humans to contruct. Maybe to some other culture, this is a small puppy. If it's a rock, it's one hell of a formation. Natural, but gigantic, rock spire ejected from a surface somewhere far-flung, perhaps? Hodge podge of smaller rocks mashed together through space & time into a cosmic finger? A giant space poo from an unknown immense creature? Who knows. We should get our own probe out there some day to see it up close & personal
