Scan interstellar traveling objects suspected of alien spacecraft

Astronomers plan to scan another long asteroid that is often sent by an alien astronaut.

A group of alien hunting scientists, headed by Russian billionaire Yuri Milner, will scan this week before celestial bodies fly out of sight of telescopes on Earth, according to Science Alert. 'Oumuamua was discovered flying over the Earth last month and was the first to visit the solar system.

Researchers want to search for radio signals and assume that the object may be an alien spacecraft.

Milner, the merchant behind Breakthrough Listen , the project worth $ 100 million to search for alien intelligence life, received an email about the asteroid 'Oumuamua last week from a senior scientist.

"The more I studied this object, the more unusual it was for me to see its shape, which made me wonder if it could be an artificial exploration ship sent by an alien civilization , " said the teacher. Professor Avi Loeb, head of Harvard's astronomy department and Milner's advisor in the Breakthrough Listen project, writes in an email.

According to Professor Loeb, the unusually long form of 'Oumuamua is quite strange compared to a normal celestial object but is ideal for a mid-star flying ship.

"Researchers who specialized in space travel in the big distance previously thought that cigarette-shaped or needle-like shapes are the most suitable structure for interstellar spacecraft, because this shape helps minimize ghosts. And if Oumuamua is more likely to be of natural origin, researchers have yet to agree on its origin, and Breakthrough Listen has a good reason to explore. "Oumuamua is an artificial object , " the research company said.

The alien hunting project will use the Green Bank telescope in West Virginia, USA, to serve research. 'Oumuamua is at about twice the distance from Earth to the Sun but in this range, the Green Bank telescope can still get the smallest signal.

Milner and his colleagues wanted to measure the celestial body before it was beyond the scope of the scanning device on Earth. 'Oumuamua will fly over Jupiter in the next year and surpass Pluto in the 2020s. "Whether it is an artificial object or not, we will obviously know more about it," The Atlantic quoted Milner. .

'Oumuamua, also known as C / 2017 U1 , made scientists confused when flying through the Earth at a tremendous speed in November. The body was first discovered by a telescope in Hawaii on 18th. 10 and observed 34 separate times in the following week.

'Oumuamua, also called C / 2017 U1.

Moving at 44 km / sec, the celestial body is flying away from Earth and the solar system. It is 400 meters long, 10 times the width. The size ratio is larger than any asteroid or comet that has been observed in the solar system so far.

However, the reddish hue and the changing brightness of celestial bodies are very similar to those in the solar system. Despite its unusually long shape, 'Oumuamua can provide new evidence for how other star systems form in the universe.
