When the interstellar object Oumuamua was discovered in 2017, it sent shockwaves through astronomy. Oumuamua's strange cigar shape and its origins from another solar system were unlike anything ever seen before. The professor at Harvard University, Abraham Loeb, suggested that the interstellar object could be an alien probe. And after an incredible discovery, Professor Loeb was back in the news – an extrasolar asteroid actually hit Earth in 2014.
Loeb and his assistant assistant Amir Siraj believe that space rock travel faster than expected, as evidence of an extrasolar visitor. 19659003] If the theory of its astrophysicists about this extrasolar asteroid turns out to be correct, it will be the first known occurrence of an object from another star system that has ever hit our planet.
And even more incredible, the Harvard space researchers believe there is a possibility that this object even brought with it evidence of an extraterrestrial life.
Professor Loeb's team searched the database of the Center for Near-Earth Object Surveys for Asteroids, which traveled faster than usual.

The researchers found three hits, two of which were rejected for incomplete data.
The third described an asteroid that was supposed to be a little less than a meter wide on January 8, 201
The speed of the asteroid had been measured at 135,000 miles per hour (216,000 km / h).
Glancing at trajectory and tracing, Professor Loeb calculated the asteroid, most likely from somewhere outside our solar system.

This would make the sighting of the first known example of an extrasolar object struck in the earth.
The researchers report that the high speed of the object indicates that it was likely ejected from another star system.
And if that were the case, it would have been deep in the interior of a planetary system somewhere near its star – possibly in its "Goldilocks Zone," meaning there is a chance it will bear life.
Researchers have written a paper in which they describe their findings, which they have submitted to The Astrophysical Journal Letters.

] And although this theory is a scientific long shot, the discovery of fragments of this extrasolar object would be Contain evidence of extraterrestrial life, a discovery of unimaginable import.
For this reason alone, it's worth speculating.  And even if it contained no evidence of life, retrieving such an interstellar object would be quite extraordinary.
There are many "ifs" to this object, not to mention that the likelihood of finding fragments of each is very small, it's the s. The discovery still gives us the ability to find other objects like them, that could have hit the earth sooner or later.
