Well, it's technically the universes first interstellar object. One that was found in 2017 by scientists. What does "interstellar object" mean exactly? That would be an object that is flying through space yet isn't tied to the gravity or pull of a star or other object. So basically, it's something that is hurtling through space on its own without anyone's help. Unlike things like comets and asteroids which are given direction and form via things like collisions and planetary gravity. This is why Oumuamua is so special in the eyes of scientists, because at points in their research on it, they found that Oumuamua was actually going faster and faster as it traveled through space...even though it wasn't passing through anything or by anything that would allow it to do that. Technically speaking, there are other objects in the universe that move around like Oumuamua, but because of the oddity of the object, as well as the fact that it's over 3000 feet in length, there are many people who feel that this isn't some kind of random space object. Instead...they think it's an alien craft! No, really, people honestly felt that this was an alien craft of some kind, to the extent that there was heavy research into thinking about what it would mean if it was an alien craft. But, then, a study that came out in 2019 all but proved that this was a comet, albeit an irregular. One, even going so far as to state how it gets extra propulsion via its movements and gasses that are emitted. “The [study’s] overall reasoning seems sounds, and the results are a really good match to the observed characteristics of ‘Oumuamua,” Marco Micheli, a scientist at the European Space Agency told Scientific American. But others still aren’t convinced that Oumuamua is a comet. “It does not look like at least 99.999 percent of the solar system’s comets,” Avi Loeb, astrophysicist at Harvard University, also told Scientific American. Loeb is also one of the scientists who thinks ‘Oumuamua might be an alien artifact. This would hardly be the first time that people think that an object from space is an alien craft or device of some kind. But, it would be the first time that it happened in the modern era to such a degree. Either way, people have been studying Oumuamua for a very long time, and through some studies, a new theory has been born as to how this thing might have been born. According to some, they feel it is probably a fragment of a larger body that was torn apart by gravitational forces during a close flyby of its native star, a new study suggests. If you're not sure what that means, think of it like a giant asteroid flew through space, and then it got caught partially in the gravity of a star. The gravity well pulled out chunks of rock from this asteroid, and boom, Oumuamua was born. Or at least, that's what the theory states. This "tidal fragmentation scenario not only provides a way to form one single 'Oumuamua but also accounts for the vast population of asteroid-like interstellar objects," lead author Yun Zhang, of the National Astronomical Observatories of the Chinese Academy of Sciences, said in a statement. So, overall, does this theory work? Technically, yes. We know that asteroids or massive entities of rock, earth or stone in space are the cause of many things like meteors and meteorites and even comets at times. Them colliding with each other is a big reason why space is full of space junk, as well as why planets like Mars have been pelted with collisions over the years. So the notion that Oumuamua came from one of these massive rocks is not only logical, it's plausible. The hypothesis explains 'Oumuamua's weirdness as well, according to Zhang and study co-author Douglas Lin, an astronomer at the University of California, Santa Cruz. That weirdness is extreme and multilayered. For example, 'Oumuamua is highly elongated, like a big space cigar (and may be somewhat flattened as well). Astronomers had never before seen a cosmic object with that shape. Granted, that honestly is because we've only seen a small fragment of comets, asteroids, meteors and such in space. So there's no way to know just how many shapes of them are out there. But this one is definitely visual, and funny if you think about it. #InsaneCuriosity #Oumuamua #RecentSpaceDiscoveries
