Astronomers have uncovered the mysterious past of a "alien ship" flying past Earth
Astronomers at the University of Queens in Belfast found that the interstellar asteroid Oumuamua, nicknamed the "alien ship", rotates chaotically. According to the findings of the researchers, the anomaly is caused by a collision with another space object. This is reported in a press release on Phys.org.
Scientists have analyzed measurements of the brightness of the asteroid and found that Oumuamua does not have a stable axis of rotation, as in other small objects of the solar system. Simulation has shown that the abnormal behavior of the celestial body will last billions of years before it again begins to rotate normally due to the impact of internal stress. The inconsistency of the axis is due to a collision with another asteroid, which threw Oumuamua out of its native planetary system into interstellar space.
Oumuamua is the first interstellar object that man could discover. The asteroid of the cigar-shaped form reaches in length of 400 meters, and in diameter - about 30 meters. The object was discovered on October 19, 2017 at a distance of 0.2 astronomical units from the Earth.
The scientists of the Breakthrough Listen project admitted that the interstellar object of Oumuamua can be a spaceship of aliens.
