In the photo from the space station, the comet is captured just above Earth’s horizon, which is illuminated by a bright light — also known as airglow — that occurs in the planet’s upper atmosphere when atoms and molecules emit light after being excited by sunlight.

Experts think the comet started breaking up last week, but it's still putting on a show for star gazers for a few more days.

January 2025 hosts extraordinary celestial events, including the rare appearance of Comet G3 ATLAS, visible once every 160,000 years. Optimal viewing

Perfect weather has opened up Adelaide’s skies for an event of a lifetime that won’t happen again for about 160,000 years. The G3 Atlas comet is currently visible in the Southern Hemisphere as it passes overhead.

Comet G3 ATLAS (C/2024) is expected to reach its maximum brightness tomorrow. The celestial phenomenon may even outshine the planets Venus and Jupiter. The comet was first spotted by the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey in Chile on April 5, 2024. It was at magnitude +19 then and hard to spot due to its faintness.
