Need a refresher about 3I/ATLAS? Here's everything to know about the interstellar object, including when the latest observations will be made.

Object 3I/ATLAS is now too far from Earth to aim a telescope at, but prior observations showed some unusual behavior. The anomalous nature of the object led astrophysicist Avi Loeb to apply a thought ...

Astronomers recently discovered a rare interstellar object passing through our solar system, and a Harvard physicist is sounding the alarm that its strange characteristics might indicate it’s more ...

Earlier this year, astronomers spotted a mysterious interstellar object, dubbed 3I/ATLAS, hurtling through the solar system at a blistering speed. It’s only the third confirmed interstellar object to ...

The core of Jupiter, the largest planet in our solar system, has long been a source of mystery for astronomers: an object so unfathomably dense and hot that it defies comprehension. Conventional ...

The interstellar object hurtling toward the inner solar system, where Earth is located, is much larger than previously thought, astronomers say.

A Harvard physicist who sounded the alarm earlier this month about a rare interstellar object passing through our solar system — suggesting it might be more than a comet — now says it could even be a ...

Interstellar object 3I/ATLAS — which is zooming through our inner solar system — appears to be emitting its own light, according to Harvard astrophysicist Avi Loeb. The observation by Loeb, if ...
