Comet news, features and articles

Newly discovered comet C/2025 V1 (Borisov), which has some minor similarities to 3I/ATLAS, will make its closest approach to Earth on Tuesday (Nov. 11). However, despite recent rumors, the two objects are not related to one another.

A researcher has captured comet 3I/ATLAS glowing green and hiding its tail in a new image from the Lowell Observatory's powerful Discovery Telescope as we enter a critical observation phase for the interstellar visitor.

New photos show that the recently discovered comet C/2025 K1 (ATLAS) developed a surprising golden glow after reaching its closest point to the sun. Until now, the comet has gone under the radar, largely thanks to the more famous interstellar comet 3I/ATLAS.

Recent observations of the interstellar object 3I/ATLAS show that it has developed a faint blueish hue, hinting at a potential color change. This is the third time experts have seen the comet's coloring shift since it was discovered.

An astronomer has snapped comet 3I/ATLAS using the Lowell Observatory's powerful Discovery Telescope, as well as his own small telescope. The new photos are believed to be the first optical observations of the interstellar visitor since it disappeared behind the sun.

The interstellar comet 3I/ATLAS has a thick irradiated crust that no longer resembles its home star system, simulations and James Webb Space Telescope observations have found.

Interstellar comet 3I/ATLAS is briefly out of view as it travels around the sun this week, but researchers and amateur astronomers used spacecraft data to track its progress right up until perihelion.

An astronomer in Italy caught a fortuitous image of the bright comet Lemmon seemingly entwined with the glowing trail of a "shooting star."

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.
