Harvard scientists: Interstellar Oumuamua object may be alien probe

At least, that's what astronomers from Harvard University suggest in a research paper.

"But, Loeb said, the fact that we've observed one interstellar object like Oumuama suggests that others may be out there". Oumuamua baffled scientists past year due to its unique speed and trajectory: as it passed through our solar system, Oumuamua accelerated.

The object has been described as "a dark red highly-elongated metallic or rocky object, about 400 metres long, and is unlike anything normally found in the solar system".

While it's not explicitly clear that Oumuamua was sent by aliens, researchers used meticulous mathematical analysis to make the case that the object was a "lightsail of artificial origin" due to the way it sped up as it passed by the sun.

Oumuamua "might be a lightsail of artificial origin", the paper says, referring to an object created to use solar radiation for propulsion. The word Oumuamua in Hawaiian language means "a messenger reaching out from the distant past".

When the object - known as Oumuamua - flew past the sun, astronomers rushed to find out more about it and reviewed data discovering that the object gained speed instead of slowing down.

It's been dubbed a comet, an asteroid, and a new class of interstellar object. The object has left our solar system and is no longer visible even with telescopes. These astronomers claim that the object could actually be "a lightsail of artificial origin" sent from some far-away civilization in the Universe.

One of the major revelations from the Direct was that there are no trophies in the game, unlike all the previous Smash Bros . Ultimate , just short of actually throwing a character (or better yet, a deejay llama) into the game.

Oumuamua was the first interstellar object to ever be seen by mankind, with unusual characteristics such as its "extreme aspect ratio" and "spinning motion".

"In science", he said in an email, "we must ask ourselves, "Where is the evidence?, not "Where is the lack of evidence so that I can fit in any hypothesis that I like?"

'Oumuamua also travels in a complex tumbling spin, but a functioning solar sail would have a much smoother path and obvious radiation-driven acceleration, Jackson said.

Mr Bailer-Jones led a group of scientists earlier this year who identified four dwarf stars as likely origin points for Oumuamua.

"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. Not all shells are the same, and similarly only a fraction of the interstellar objects might be technological debris of alien civilizations.

The latest theory shedding more light on the nature of Oumuamua comes from a study carried out by two astronomers from the Harvard Smithsonian Center for Astrophysics.
