Did an alien space probe pass near Earth a year ago?

The scientists sought to explain quirks in Oumuamua's movement by calculating whether it could be powered by the sun's radiation.

The Oumuamua was spotted late a year ago as it drifted into the solar system and passed close enough to the sun that it could be seen on observational telescopes.

The truth is out there regarding the origins of a mysterious cigar-shaped object seen tumbling through the solar system past year, according to researchers from Harvard University who argue it may have been an alien spacecraft sent to investigate Earth. The metal-rich object was found to be about 750 feet by 115 feet and reddish in colour.

Oumuamua has now left the solar system and is no longer visible even with telescopes.

Although it's been called a comet or an asteroid in the past, it's still unclear exactly what the elongated, red-tinged object is and where it came from.

Just in case, astronomers pointed powerful radio telescopes at the object to scan for radio transmissions. Scientists have also been unable to concretely identify it as a comet because it lacks a tail or "coma" around it.

Asked if he thought his team need to improve against Inter, Pochettino said: "I always want more from the team". I think we need to improve. "The belief is still there, you know me, I am so optimistic".

But since Oumuamua's discovery, scientists have continued to wonder whether it could have originated from some intelligent life-form.

Two Harvard researchers have written a paper for The Astrophysical Journal Letters that suggests the idea that Oumuamua might be "a fully operational probe sent intentionally to Earth vicinity by an alien civilization".

"It is impossible to guess the goal behind Oumuamua without more data, [but the object] may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization". But the way the object sped through space leads the team to believe the otherworldly craft was propelled by some sort of "lightsail of artificial origin". However, he adds that, if Oumuamua is indeed a lightsail, it may have run into our solar system "like a ship bumping into a buoy on the surface of the ocean".

In a paper to be published November 12 in The Astrophysical Journal Letters, the pair declare that the reddish, elongated, stadium-sized object "may be a fully operational probe sent intentionally to Earth vicinity by an alien civilization", NBC News reported. Do you think the interstellar object was actually an alien probe? Traveling at 44 kilometres per second, the comet is headed away from the Earth and Sun on its way out of the solar system.

"A survey for lightsails as technosignatures [scientific evidence of past or present technology] in the solar system is warranted, irrespective of whether Oumuamua is one of them", the paper said.
