Scientists mention the possibility that Oumuamua is an extraterrestrial spacecraft

Maybe it's a boat extraterrestrial.

Scientists were confused about Oumuamua since it's been observed that the mysterious space object has gone beyond the Sun at the end of 2017.

Given its high speed and unusual trajectory, the reddish color, the size of a stadium, clearly came from outside. solar system, reports NBC.

But its flattened and elongated shape and its way of speeding around the world the solar system distinguishes it from conventional asteroids and comets.

Now, some researchers from Harvard raise the possibility that Oumuamua to be an extraterrestrial spaceship.

As it says in an article to be published on November 12 in The letters of the astrophysical journal, the object "it can be a fully operational probe intentionally sent to Earth by an extraterrestrial civilization"

What is Oumuamua?

Last year, a ghostly visitor went through the solar system and astronomers watched him disappear into space, hoping to gather information as he was leaving our system. It was a first cosmic: The first interstellar asteroid observed.

Near the sun, where it is too hot for the ice to remain frozen, these remains are called asteroids. Further, where the ice remains solid, these bodies become the nucleus of possible comets.

We also know that sometimes the gravitational interaction between these objects and the larger planets of our solar system can throw them into interstellar space fast enough to escape the gravity of our Sun. When this happens, they become interstellar vagabonds, lost in the void of the galaxy.

Last year, astronomers studied the first of these vagrants among another discovered planetary system that crosses our own.

When the telescope Pan-STARRS originally detected in Hawaii on October 19, 2017, observers thought it was a comet, one of the many that fall out of the limits of our own solar system and that we discover each year as the sun approaches.

However, the newly detected object had already turned near the Sun. When the observations did not reveal any of the confusions normally associated with comet thaw, they were reclassified as asteroid.

But a more detailed examination of its orbit showed that this object was not gravitationally bound to the Sun not at all. It was just happening: The first asteroid observed from another planetary system.

He was given the name of Oumuamua, which in Hawaiian means something similar to "first messenger from afar"

Oumuamua came into our Solar system of the direction of the Vega staralthough astronomers could not trace their origin in any particular star system. After turning around the Sun, he left the solar system towards the constellation of Pegasus.

After their close encounter with the Sun, Oumuamua traveled at a speed of 100,000 km / h, and astronomers struggled to collect as many observations as possible and learn more about the situation of this interstellar traveler.

They confirmed that he is relatively smallits color shows that it is a dark reddish color similar to some asteroids of our own planetary system. The way its brightness varies indicates that it turns and gives clues to its shape, which is very unusual, much more elongated than any asteroid seen before, probably up to 10 times more than its width.
