A team of Harvard University He says that an interstellar object, which goes beyond the Solar System, hit Earth five years ago.

The researchers, one creator of the theory that Oumuamua is an old alien ship, point out that the "interstellar traveler" crashed into the sky over Papua New Guinea, according to a pre-published study on the Arxiv.org platform.

The report, signed by the controversial physicist Avi Loeb and Amir Siraj, He further states that these impacts are very common. Now the research must be evaluated by its peers to be published in Astrophysical Journal Letters.

After analyzing the fastest meteors collected in a catalog covering the last 30 years, the researchers detected one in particular that, because of their orbit and speed, seemed to originate in a region of space outside the solar system.

The object traveled at 60 kilometers per second and, after tracking the orbit, suggests that came from the deep interior of a planetary system, or a star on the Milky Way's disk.

"We discovered that one of these meteors had to have been traveling extremely fast to hit Earth in the direction and speed he made, "Siraj tells Newsweek.

"In fact, he was traveling so fast that he should have been released from the Solar System, which means that, as & # 39;Oumuamua, originating from outside the solar system, "he adds.

Siraj says that instead of looking into space, it is better to look on Earth, because these interstellar objects collide all the time against our planet.

The physicist explains that we did not notice the impact because the object measured less than half a meter.

Loeb, head of the Harvard Astronomy Department, caused controversy by publishing a study stating that a huge rock that runs through our solar system, which intrigued the astrophysicists, could be an alien spacecraft.

"Oumuamua"as it was called, was discovered in October 2017 by the Pan-STARRS1 telescope in Hawaii and therefore its name, which means" messenger "in Hawaiian, is about 400 meters long and 40 meters wide and was recorded by several telescopes as the first known object coming from another star system.
