Computer simulations confirm that ‘Oumuamua – an object from another star system that sped near our sun in 2017 – likely formed via a close encounter with its star. ‘Oumuamua may have originated in a debris disk, they said, or even a shattered super-Earth.

‘Oumuamua – the weird object that entered our solar system in 2017 and quickly fled back toward interstellar space – might not be an asteroid or comet from a distant solar system, as many believed. It might instead be a “cosmic dust bunny.”

“We were looking for a signal that would prove that this object incorporates some technology.”

The object we call ‘Oumuamua entered our solar system a year ago and quickly left again. It’s a very puzzling object. Could it be an alien lightsail? A new paper from Harvard discusses that possibility.

The 1st object known to be from another solar system passed through our solar system a year ago. Where did it come from? Astronomers have identified 4 plausible candidates.

You’ve probably read about this unprecedented visitor from interstellar space. Astronomer Guy Ottewell thought you’d like to see its trajectory through our solar system.

“What if extraterrestrial intelligences are not like us, but are found in the frigid reaches of the outer solar system, the extreme gravity of neutron stars, the brilliant cores of active galaxies, or the hearts of the richest galaxy clusters?”

In the first discovery of its kind, researchers in France have found 19 asteroids in our solar system – between the planets Jupiter and Neptune – that they say are likely of interstellar origin.

The first known interstellar comet – 21/Borisov – probably came here from a red dwarf star, according to a new study of data from the Hubble Space Telescope.

2020 has been an exciting year so far for SETI – the search for extraterrestrial life – in terms of new technological developments and strategies.

Hyperbolic comets fly through our solar system at high speed before heading out to interstellar space, never to return. A new study from astronomers in Japan identifies 2 hyperbolic comets that likely originated outside our solar system.

The 1st interstellar object – 1I/’Oumuamua – had already passed closest to our sun when astronomers first spotted it. So catching this 2nd one – 2I/Borisov – prior to perihelion was a big plus for astronomers! Before and after images here.

The fascinating object 2I/Borisov has been steadily brightening as it nears its encounter with our sun. It’ll pass closest to the sun on December 8, 2019, then flee again toward interstellar space.

Astronomers think the object they’ve labeled C/2019 Q4 – discovered August 30 – came from a place far, far away. If confirmed, it’s only the 2nd interstellar object ever detected, after ‘Oumuamua in 2017.

What happens when young stars brush past each other? A lot, according to a new study suggesting our solar system contains comets stolen from another star 4.5 billion years ago.

‘Oumuamua – 1st known object to sweep past us from beyond our solar system – caused a stir when astronomers spotted it in 2017. Now a new study suggests another interstellar object might have hit the Earth in 2014.

Only a small number of hypervelocity stars have ever been discovered. Now ESA’s Gaia mission has revealed 20 more.

Mysterious asteroid 2015 BZ509 – currently nestling in Jupiter’s orbit – became less mysterious once astronomers realized it’s an immigrant, captured from another solar system.

Scholz´s star – named for its discoverer – is now 20 light-years away. But astronomers say they’ve verified a flyby of this star 70,000 years ago that disturbed comets in the Oort Cloud.

New research suggests that the 1st confirmed interstellar asteroid – called ‘Oumuamua by astronomers – likely came from a system where 2 stars orbit each other.
