Watch On

Tune in on Nov. 24 to watch live telescopic views of the fractured comet C/2025 K1 (ATLAS), which recently broke into multiple large pieces following a close brush with the sun.

The livestream, courtesy of the Virtual Telescope Project, begins at 10 p.m. EST on Nov. 24 (0300 GMT on Nov. 25) and will feature live views of C/2025 K1 (ATLAS) from the organization’s suite of robotic telescopes located in Manciano, Italy, weather permitting.

Comet C/2025 K1 (ATLAS) was discovered barrelling towards the sun on May 24, 2025 and is believed to have originated from the Oort cloud — a frozen shell made up of billions of icy bodies that surrounds the solar system.

The comet reached perihelion, its closest approach to the sun, on Oct. 8, when it passed just 31 million miles (50 million kilometers) from our star. On the night of Nov. 11, astronomers watched as the object dramatically fractured into at least three large pieces, likely as a result of the intense heating it absorbed at perihelion, which may have undermined the structural stability of its central nucleus.

Comet C/2025 K1 (ATLAS) is not in any way related to the interstellar comet 3I/ATLAS, which was confirmed in July to be just the third body to visit our solar system. Rather, the shared “ATLAS” designation stems from the fact that they were both found by the NASA-funded Asteroid Terrestrial-Impact Last Alert System (ATLAS) program.

The fractured comet is currently too dim to be seen by the naked eye, but can still be spotted with the aid of a small backyard telescope close to the stars of the famous Big Dipper asterism in the constellation Ursa Major, or captured in long exposure photography!
