Colorful cosmic "fireworks" decorate the night sky over the La Silla observatory in Chile in this gorgeous image by the European Southern Observatory's resident astrophotographer Petr Horálek. Above the Milky Way and to the left are two nebulas that appear to form a question mark in the sky: an arc known as Barnard's Loop and the nearly-circular Angelfish Nebula right below it. These two nebulas are part of the Orion Molecular Cloud Complex. — Hanneke Weitering
