The Orion Nebula is a cloud of interstellar dust which can be found just below Orion's belt in the constellation of the same name. It's so bright that on a clear night you can see it with the naked eye. Astronomers love it because it contains loads of cool astronomical objects and phenomena, like star formation, brown dwarves, and protoplanetary discs. 100% organic cotton sateen (super soft with a slight sheen)
