This was not sent by aliens to save us

You may have seen a headline recently claiming that the interstellar comet that visited our solar system last fall could actually be a spacecraft sent by an alien civilization.
I’m here to report that no aliens are coming. At least, not this time.
Scientists have been puzzling over the cigar-shaped comet, dubbed ‘Oumuamua after the Hawaiian word for “messenger,” since it was first spotted swooping past the planets at an odd angle. Its speed was so blistering and trajectory so strange that scientists concluded it had to be a visitor from another star. Subsequent observations by dozens of telescopes in every wavelength of the electromagnetic spectrum suggested it was an inert (if extraordinary) space rock — dense,

Rehbogen is accused of working as a guard at the camp east of Danzig, which is today the Polish city of Gdansk, from June 1942 to about early September 1944.

people were killed at Stutthof and prosecutors argue that as a guard, he was an accessory to at least hundreds of those deaths.
The retired civil servant showed no reaction as prosecutor Andreas Brendel read the accusations against him, detailing the horrific way prisoners at Stutthof were killed. Some were given lethal injections of gasoline or

But then a preprint of a research paper to be published in the Astrophysical Journal appeared online this week, posing an “exotic scenario” in which the ‘Oumuamua was a

“Anyone who heard the screams from outside the gas chamber would have known that people were fighting for their lives,” Brendel said.

solar-powered probe built by an alien civilization.
There’s no actual evidence to support this idea. Indeed, the majority of the study is devoted to examining how radiation pressure from the sun might push on a natural object and contribute to ‘Oumuamua’s unexplained acceleration. This phenomenon is the basis for a proposed method of spacecraft propulsion called light sails, which I guess is how we get from “whoa, weird rock” to “it might be aliens!” The study authors justify their speculation by arguing that the probability of an ordinary comet intercepting our solar system after being ejected by its home star is very small.
As astrophysicist Katie Mack pointed out on Twitter, coming up with far-out explanations for slightly strange phenomena is one of astronomers’ favourite parlour games. (Remember the alien megastructure that turned out to be a star swathed in dust?) Johann Rehbogen says he didn’t know of the killings at Stutthof.
