An interstellar mission to a black hole may sound impossibly bold, yet a new concept by astrophysicist Cosimo Bambi of Fudan ...

NASA's Hubble captured the clearest image of interstellar comet 3I/ATLAS, the third such object observed. This comet, traveling at 130,000 mph, offers ...

The new interstellar comet's official name is 3I/ATLAS. It's officially the third known interstellar object to pass through our solar system, and it poses no threat to Earth.

An "interstellar object" is speeding toward the inner solar system, where Earth is located, astronomers have confirmed. The object -- likely a comet -- was first detected in data collected between ...

In comparison, the first known interstellar visitor, 1I/'Oumuamua, had an eccentricity of about 1.2, and 2I/Borisov came in at 3.6. 3I/ATLAS massively outpaces both.

Astronomers are rolling out a welcome mat for a newly identified visitor from beyond our solar system. The object — thought to be a comet — is only the third-ever confirmed interstellar ...

Anatomy of an interstellar object Comet 3I/ATLAS follows two other intriguing interstellar objects, called ISOs, that once passed through our solar system: ‘Oumuamua in 2017 and 2I/Borisov in 2019.

NASA has named this latest interstellar object 3I/ATLAS, after detecting it this week with the NASA-funded ATLAS (Asteroid Terrestrial-impact Last Alert System) survey telescope in Rio Hurtado, Chile.

For only the third time, astronomers have found something passing through our solar system that came from outside the solar system. This interstellar object, known as 3I/ATLAS, is still pretty far ...
