This beautiful photo shows comet C/2024 G3 (ATLAS) flying near Earth, as seen by astronaut Don Pettit on the International Space Station on 11 January. It was first spotted by NASA’s Asteroid Terrestrial-impact Last Alert System last year, when it was 600 million kilometres away. Its orbit around the sun takes 160,000 years, so we have a long wait before it returns.
