It has been blown into a bubble shape by a stellar wind from a massive young and hot central star. The colours highlight emission from different elements: doubly ionized oxygen (O III,blue),hydrogen-alpha emission (H-alpha,green),and nitrogen emission (N II,red). The Bubble Nebula is 7100 light years from Earth in the constellation of Cassiopeia.
