Wait a second, was that weird interstellar object an alien spacecraft after all?

One of the most weird pieces of space news that keeps us going this year is the story of Oumuamua, a cigar-shaped object that sped through our solar system so fast that scientists barely had time to glimpse it before it was already headed back out into office. It's the first interstellar object mankind has ever seen, and it's sparkled at your headlines and what exactly it was.

Early on, the object was thought to be a comet, but it was obviously an asteroid. The scientific community at large has changed its mind, but it is unclear what the majority of astronomers actually believe, but at least a couple of them are still entertaining the possibility that the object is actually an alien spacecraft. Yes, this is still a thing.

After Oumuamua's shocking appearance in our system, researchers from the Breakthrough Listen project pointed to the mechanical hearing. If it were an alien ship, surely it would be communicating with its handlers and we might be able to hear those whispers, or at least that was the plan. Unfortunately, the team heard only silence, but that is not the case for some of the possibilities of Oumuamua being a spacecraft sent to our Solar System or even Earth, specifically.

In a new paper, Scientists from the Harvard Smithsonian Center for Astrophysics for the Cigarette-Shaped Object of Extraterrestrial Origin. More to the point, they focus on the object and their system. Oumuamua sped up as it left, which is obviously very odd behavior for a rock, which led to some scientists to assume it was a comet, spewing out gas and material as it cruised back to interstellar space.

This new paper suggests that it could be speeding up because it is equipped with a "light sail." A light sail is an advanced, but still theoretical, form of spacecraft propulsion that would use object along, like a sailboat's sail. If solar particles slam into the sail, it causes the sail and whatever it is attached to to speed up.

"Considering an artificial origin, one possibility is that it is an important issue, it can not be used in the future. way to our system. However, the team may be more likely to have an open source theory, saying that it may be more fully operational than it is intended to be in the vicinity of an alien civilization.

What this paper is more than anything that we did not know why, it was here, how it moved in the way that it did. There are plausible natural processes that might have done the trick, or maybe it really was aliens. We can never know for sure.
