They took one good look at this place and said 'bugger that!'
Exactly!

Apparently not a peep was heard from `Oumuamua.

Quote
No alien signals have been detected from an interstellar, cigar-shaped space rock discovered travelling through our Solar System in October, researchers listening for evidence of extraterrestrial technology said Thursday.

The object, dubbed Oumuamua, was spotted by several Earthly telescopes two months ago.

Given its weird trajectory, surprised researchers immediately concluded it was from beyond our planetary system—the first interstellar object ever identified in our midst.

The rock is thought to be about 400 metres (1,300 feet) long, and thin—only about 40 m wide, a never-before-seen shape for an asteroid.

After its discovery was announced last month, a project called Breakthrough Listen, dedicated to finding signs of extraterrestrial intelligence, said it would study the rock for artificial signals.

"No such signals have been detected" by its network of telescopes, the project said Thursday, adding: "the analysis is not yet complete".

Its surface appearance is a fairly close match to objects found in our own solar system.

Scientists at Queen's University Belfast have led worldwide investigations into a mysterious object that passed close to Earth after arriving from deep interstellar space.Since the object was spotted in October, Professor Alan Fitzsimmons and Dr Michele Bannister from the School of Mathematics and Physics at Queen's University have led an international team of astronomers to piece together a profile of the strange visitor, which has been named `Oumuamua.

The team was made up of researchers from elsewhere in the UK, the US, Canada, Taiwan and Chile and in total seven researchers from Queen's were involved.

Professor Alan Fitzsimmons headed up a team which measured the way that `Oumuamua, reflects sunlight, and found it similar to icy objects covered with a dry crust. This is because `Oumuamua has been exposed to cosmic rays for millions, or even billions, of years, creating an insulating organic-rich layer on its surface.

The research, which has been published this week in Nature Astronomy, suggests that `Oumuamua's dry crust could have protected its icy interior from being vaporised - even though the object was just 23 million miles from our sun in September when it zipped past.

Professor Alan Fitzsimmons commented: "We have discovered that the surface of `Oumuamua is similar to small solar system bodies that are covered in carbon-rich ices, whose structure is modified by exposure to cosmic rays.

"We have also found that a half-metre thick coating of organic-rich material could have protected a water-ice-rich comet-like interior from vaporizing when the object was heated by the sun, even though it was heated to over 300 degrees centigrade."

Don't lose hope. :therethere: The Mothership will come to take Trump home.

:P
I'm just a student of the game that they taught me.
