Interstellar comet 3I/ATLAS is making its closest approach to Earth in days, and the latest telescope pics show it’s glowing green! Scientists say the color comes from wild gases like diatomic carbon. Even cooler? This comet is actually shining in X-rays, which is super rare. If you’ve got a telescope, you might be able to spot it yourself on December 19. Space nerds, this is your moment! #Science #Comet3IATLAS #SpaceNews
