New telescope images show that the interstellar comet 3I/ATLAS is shooting a giant jet of gas and dust toward the sun. This is normal behavior for comets, an expert told Live Science.

The European Space Agency's ExoMars orbiter has captured the closest view yet of the interstellar comet 3I/ATLAS. The images reveal the comet's bright coma but show no signs of a tail.

The interstellar comet 3I/ATLAS does not come from our corner of the Milky Way, and may be a time capsule of the early galaxy, new research into its trajectory hints.

A small, giraffe-size asteroid called 2025 TF came closer to Earth than some satellites on Wednesday (Oct. 1), stunning astronomers who first spotted it hours later.

Scientists spotted an enormous black hole in the early universe that's growing at 2.4 times the theoretical Eddington limit. Studying it further could help answer one of the biggest questions in astrophysics.

Three years into its mission, the James Webb Space Telescope has advanced the search for alien life more than any machine before it. What will it find next?

In a dazzling new photo, the James Webb Space Telescope zooms in on the Butterfly Nebula — the dying gasps of one of the hottest stars in the sky, which could hold clues to Earth's origins.

Astronomers using the James Webb telescope alongside Canada's CHIME telescope have pinpointed the origin of one of the brightest blasts of radio energy ever detected in Earth's skies.

The second and final 'blood moon' total lunar eclipse of 2025 is coming on the night of Sept. 7-8. Here's where the celestial spectacle will be visible — and how to watch it if you're not in the path.

A large lunar crater featured in the iconic 'Earthrise' photo has just helped the European JUICE spacecraft hone its alien-hunting instruments during a once-in-a-lifetime flyby.
