Study Finds Weird Interstellar Object ‘Oumuamua Isn’t As Big As We Thought

Scientists have learned more about ‘Oumuamua, the hunk of matter that is the first known interstellar object to ever be detected by scientists within the boundary of the solar system. Specifically, observations performed by researchers using the Spitzer Space Telescope and published in The Astronomical Journal have determined that prior observations likely established too generous an upper boundary on how large it could be.

No, ‘Oumuamua Is Probably Not an Alien Spaceship

On 19 October 2017, a strange object from outside the Solar System whizzed by the Earth, exciting scientists and non-scientists alike. Immediately, some people speculated that this interstellar visitor could be an alien spacecraft. But we’re here to report that, despite a recent paper, there’s no reason to think ‘Oumuamua is an alien ship. Read More >>

Why a Mission to a Visiting Interstellar Object Could Be Our Best Bet for Finding Aliens

Life may exist elsewhere in the Milky Way galaxy, though try as they might, scientists have yet to detect any sign of it. Part of the problem has to do with the size of space; finding traces of organic substances or the waste signatures of alien megastructures isn’t easy at such cosmic distances. Fortunately, there’s the possibility that alien life will come to us in the form of interstellar objects. Read More >>

Interstellar Comet ‘Oumuamua Has a Built-In ‘Propulsion’ System

Remember that cigar-shaped interstellar object that whizzed through our Solar System last year? It was pretty weird, right? Well, new research shows ‘Oumuamua is even stranger than we realised. Read More >>

The ‘Oumuamua Asteroid Likely Came From a Tatooine-Like Star System

Last October, astronomers detected the very first interstellar object, an asteroid dubbed ‘Oumuamua. New research suggests this visitor from afar likely came from a binary star system, and that astronomers should be on the lookout for both interstellar asteroids and comets. Read More >>

Interstellar Asteroids Like ‘Oumuamua Could Rewrite the Origins of Life on Earth

Late last year, astronomers detected the first known interstellar asteroid, dubbed ‘Oumuamua. New research suggests these exotic objects are more abundant than we thought, an observation that boosts the panspermia hypothesis—the idea that asteroids seeded life on Earth. At the same time, the presence of so many foreign objects in our Solar System could also change the way we search for extraterrestrial life. Read More >>
