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.

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.

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.
