The mysterious interstellar object called ‘Oumuamua was discovered about two years ago, and it seems that new details about its origin are revealed.
Fox News reported that a study that’s been recently published in March, the object is said to have been ripped from a larger object due to the gravity from a nearby star.
“We showed that ‘Oumuamua-like interstellar objects can be produced through extensive tidal fragmentation during close encounters of their parent bodies with their host stars, and then ejected into interstellar space,” according to the study co-author, Douglas Lin.
Fox News reported that she and three more experts used computer simulations in order to show how objects such as ‘Oumuamua can form under the influence of tidal forces such as the ones felt by the earth’s oceans.
‘Oumuamua was discovered back in 2017 and this object is unlike any other celestial object that experts have seen before. This is due to the strange shape and very dry surface as well.
Lots of researchers believed that this is an alien probe, but now, Yun Zhang, the study’s lead author said that this is not the case.
“It is really a mysterious object, but some signs, like its colors and the absence of radio emission, point to ‘Oumuamua being a natural object,” Zhang explained.
Alien origins are simply speculations
It’s also important to mention that a study published in November 2018 from the Harvard Smithsonian Center for Astrophysics suggested that the object could be “a lightsail of artificial origin” sent from another civilization.
The researcher who discovered ‘Oumuamua is the Canadian physicist and astronomer Robert Weryk, and he also said the idea it was from another civilization was just “wild speculation.”
Fox News continued and said that on the back of ‘Oumuamuma’s discovery and the second interstellar object, Comet 2I/Borisov (August 2019), it’s safe to assume that there are many more interstellar objects waiting to be discovered.
“The discovery of ‘Oumuamua implies that the population of rocky interstellar objects is much larger than we previously thought,” Zhang said.
Zhang continued and explained that “On average, each planetary system should eject in total about a hundred trillion objects like ‘Oumuamua. We need to construct a very common scenario to produce this kind of object.”
