An ancient, rare comet is passing by Earth, and some people in the Pittsburgh area have seen the once-in-a-lifetime comet streaking across the sky. On Tuesday, KDKA-TV's Jessica Guay and Ian Smith captured the comet,

The Tsuchinshan-ATLAS comet was first discovered by observers at China’s Tsuchinshan Observatory and an ATLAS telescope in South Africa.

The Tsuchinshan-ATLAS comet is visible from the Northern Hemisphere this month—and won't be back for another 80,000 years.

Some stargazers Tuesday night were treated to a once-in-a-lifetime viewing of a rare comet. The comet, called A3 (Tsuchinshan–ATLAS), was discovered in 2023, and likely won't make another appearance in the night sky for another 80,000 years. Some were able to snap a picture of the comet in skies above southeast Indiana.

Atlas comet is still in the neighborhood and will wow stargazers in the North Hemisphere after making an appearance in the Southern Hemisphere over the weekend.

New York and New Jersey have another chance to see a rare comet tonight, as the October 2024 supermoon appears for the next few days.

In addition to comet C/2023A3, a new supermoon will be visible, and it will be the largest full moon of the year.

Tsuchinshan-ATLAS is a comet that will briefly appear in the October night sky before disappearing forever into deep space
