Scientists have discovered the truth about a mysterious space rock called Oumuamua already hurtling through the Earth, the solar system, and was spotted last year.
A group of renowned astronomers, including members of NASA, the European space agency and the German Max Planck Institute for Astronomy, released a report this week on the origin of the cigar-shaped asteroid that was first observed in October 2017.
The name Oumuamua is Hawaiian for “messenger from afar arrive first” and was the name of the site that first spotted.
According to the report, “a fast-moving object in an unbound orbit was discovered close to the Earth” by a powerful telescope, located in Hawaii.
The report claims Oumuamua is a metal or rocky object, about 400 metres long and 40 metres wide.
It has a “comet-like density” and a dark red background.
“(The red area suggests) an organic-rich surface such as that of comets and the outer solar system asteroids, or on a surface with minerals with nano-iron, as the dark side of Saturn’s moon Iapetus,” the report said.
The report suggested Oumuamua the left are the home to millions and millions of years ago, and was probably sent on his lonely road when it was “ejected during the planet formation and migration” and is linked to one of the four star systems.
It was also calculated that Oumuamua moved faster than the existing laws of celestial mechanics.
The report is accepted in The Astrophysical Journal.
The discovery of Oumuamua led to international debate when it was first discovered, when scientists struggled to explain what exactly the long, thin asteroid was and why it flew so close to the Earth.
The discovery even prompted suggestions that the rock was actually an alien spaceship, or probe, used for exploring our solar system.
But a fact remained undivided: Oumuamua is the first object that has ever been observed to travel in our solar system from deep space.
The report found that Oumuamua is likely to be “one of many interstellar objects through the Earth’s solar-energy system on a regular basis.
