How do we know 3I/ATLAS, also called comet C/2025 N1 (ATLAS), is interstellar? Will it strike Earth? Can we visit it? Here are all of your questions answered.

Astronomers are scrambling to gather data on a mysterious object that’s currently hurtling through the solar system. Preliminary observations suggest it came from interstellar space, and if confirmed, it would mark the third discovery of an interstellar object in history.

Space scientists say they are preparing a comet interceptor spaceship as the third interstellar object ever detected was spotted this week. A mysterious object the size of Manhattan was spotted by astronomers hurtling through our Solar System at extraordinary speed.

Dubbed 3I/ATLAS, the comet poses no danger to Earth and will remain roughly 150 million miles away as it speeds by.

An object from another star has been seen entering the solar system at high speed, and is expected to whip around the sun in the coming months

Astronomers have confirmed the third interstellar object on record is dashing through our solar system. Dubbed 3I/ATLAS, it appears to be a comet and is thought to have flown in from the direction of the constellation Sagittarius,

NASA scientists have discovered a rare visitor from beyond our solar system, a new interstellar comet speeding by on a brief cosmic tour.

On July 1, 2025, a telescope in Chile detected something unexpected: a faint object streaking across the sky at an unusual speed and angle. Within hours, astronomers realized what they were seeing. This wasn’t a comet from the outer reaches of our own solar system,
