Harvard Scientists: Strange Asteroid Could Be An Alien 'Probe'

They go on to wonder whether Oumuamua could have been "sent intentionally to Earth vicinity by an alien civilization".

Oumuamua has been confusing scientists ever since astronomers first sighted it back in 2017.

It's most likely a skyscraper-sized asteroid from another part of the galaxy, but what if it's actually "a fully operational probe sent intentionally to Earth vicinity by an alien civilization."

That's the most "exotic" explanation provided in a paper set to be published Nov. 12 in The Astrophysical Journal Letters, written by researchers from the Harvard Smithsonian Center for Astrophysics.

Oumuamua is interesting for a number of reasons. First and foremost, it's the first interstellar asteroid of its kind ever seen by humans. Secondly, it's an odd shape, being flat and elongated. Thirdly, and perhaps most importantly, it moves strangely. As per the paper, it shows "deviations from a Keplerian orbit at a high statistical significance". In short: It doesn't move like a regular comet or asteroid.

The paper attempts to explain that strange movement and comes up with a number of possible scenarios. The first: solar radiation pressure.

But here's where it gets weird.

"If radiation pressure is the accelerating force," states the paper, "then 'Oumuamua represents a new class of thin interstellar material, either produced naturally, through a yet unknown process in the ISM or in proto-planetary disks, or of an artificial origin."

1. Maybe they're coming back to pick up "Occasional Cortex" from New York.
