Oumuamua does not behave like any other comet and a Harvard scientist suggests it is an alien probe, but the astronomer who discovered it says it's just "wild speculation."
Robert Weryk discovered the strange interstellar object in 2017 at the Institute of Astronomy at the University of Hawaii.
"I think it's a remnant of another solar system, it's just something that shocked us, and we were very lucky to have been operating the telescope that night and looking in that direction," Weryk told CBC's Afternoon Drive.
"It has been predicted theoretically for decades, but we have never seen one until we see another, there are many questions that we just can not answer."
But the question of whether the cigar-shaped object is an alien probe, as suggested by Harvard scientists Abraham Leob and Shmuel Bialy.
"Honestly, that's a bit of wild speculation," Weryk said.
Leob is the president of astronomy at the Harvard-Smithsonian Center for Astrophysics and Bialy is a postdoctoral fellow there. His article was presented to the journal Astrophysical Journal Letters.
They hypothesize that Oumuamua "may be a fully operational probe sent intentionally to the vicinity of the Earth by an alien civilization."
"There is a maximum speed at which you can travel to be gravitationally bound by the sun.When we saw this object for the first time, it traveled faster than that, so we know for sure that it is from outside our solar system. "It was a comet that had some degbading that was not visible from the ground, so it did not look like a comet," he said.
"(The Harvard researchers) decided to focus on another aspect of that, which is an extraterrestrial spacecraft and that has a solar sail material that is causing the non-gravitational trajectory, but actually we believe that this is not true, according to the data. what acquired. "
Weryk's work in Hawaii focuses on finding asteroids that pose a danger to the earth.
"We hope that during that search, one of them is another interstellar object," he said.
Finding another object of this type would allow scientists to gather more data and test the object for more answers.
