Here’s what you’ll learn when you read this story: Our brain’s evolution makes it nearly impossible to commit to a multi-generational mission like interstellar travel, says one evolutionary ...

We know of three interstellar objects (ISO) that have visited our inner solar system. Oumuamua was the first one, and it came and went in 2017. 2l/Borisov, an interstellar comet, was next, appearing ...

Astronomers are hustling to use interplanetary spacecraft to study the interstellar comet dubbed 3I/ATLAS while the sun is hiding it from Earth When Comet 3I/ATLAS roared into the solar system this ...

An interstellar comet that originated outside our solar system just made its closest pass of the sun, setting it on an outgoing path — but it’s not leaving our cosmic neighborhood yet. The comet, ...

The interstellar object 3I/ATLAS is, once again, doing something strange. This interloper from another star is currently concealed from view behind the sun, leading some people to wonder what it has ...

Analyses of its emissions using NASA’s Neil Gehrels Swift Observatory indicate that the interstellar comet probably has a very different structure than comets in the solar system. Hydroxyl compounds ...

A new analysis of our solar system’s interstellar interloper, 3I/ATLAS, reveals that it’s spewing huge amounts of water — and astronomers can’t immediately explain why. The object, which is widely ...

A comet from another star system will swing by Mars on Friday as a fleet of spacecraft trains its sights on the interstellar visitor. The comet known as 3I/Atlas will hurtle within 18 million miles ...

Astronomers have a new theory about planetary formation, and it revolves around one mysterious concept: interstellar visitors. No, not little green men, but rather deep-space wanderers like the ...

The Manhattan-sized interstellar object 3I/ATLAS is now turning green as it rockets closer to the Sun — with experts stating it appears something “switched on” to inspire the “anomalous evolution.” ...
