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.

January 13, 2025, as Comet G3 ATLAS (C/2024) reaches its peak brightness. This once-in-a-lifetime spectacle marks the comet's closest approach to the Sun, bringing it within 8.7 million miles of the Sun at its perihelion.

Comet G3 ATLAS is set to shine at its brightest this week, potentially outshining Venus and Jupiter. G3 ATLASs orbit is so big that it takes roughly 160,000 year to go around the Sun. As it approaches perihelion on January 13,

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.

G3 (ATLAS) did it! It survived its perilous perihelion, getting ten times closer to the Sun than Earth does. This comet is a sungrazer comet, and the encounter made it bright – so bright that even at a considerable distance,
