Karl Battams -- a computational scientist at the U.S. Naval Research Laboratory -- confirmed the discovery of the 3,000th near-sun comet using an NRL instrument Sept. 15.

Astronomers have discovered that the largest comet from the Oort Cloud, a shell of icy bodies at the very edge of the solar system, is bursting with chemical activity. Using the Atacama Large ...

The comet's approach toward Earth coincides with a total solar eclipse on April 8. Around that time, 12P/Pons-Brooks will be at or near perihelion, the point during orbit when it's closest to the sun.

Scientists have examined the interstellar invader 3I/ATLAS, finding evidence that it is packed with water that could be older than the solar system.

On Wednesday, the comet made its closest approach to our sun and on Saturday, October 12 at 11:39 a.m. it will be just 43,911,824 miles from Earth (its closest pass).

The comet appears to burn a bright, lime green color in photographs. But Fraknoi says don't look for something green in the sky. "The naked eye just shows a fuzzy white glow," he said.

Your unusual chance to see a comet in the sky is here. C/2023 A3 Tsuchinshan-ATLAS was discovered by astronomers in 2023 — and will appear to the naked eye over the next couple weeks.

Halley’s Comet is considered a short-period comet, a comet that has an orbit of less than 200 years. On average, the comet is visible from earth every 76 years.
