A rare celestial event is lighting up the night sky this month as Comet Tsuchinshan-Atlas makes its closest approach to Earth for the first time in roughly 80,000 years.

The rare Comet C/2023 A3, also known as the Tsuchinshan-Atlas comet, is visible in the western sky shortly after sunset every night this weekend.

A ”once in a lifetime” comet is expected to light up the night sky as it passes by Earth later this week. Comet Tsuchinshan-ATLAS will be bright enough to view by the naked eye for most of October. Here’s how to make sure you don’t miss the rare sighting.
