VY Canis Majoris


VY Canis Majoris is a red hypergiant and pulsating variable star which is extremely rich in oxygen. It’s about 3,900 light-years from Earth in the slightly southern constellation of Canis Major. It is one of the largest known stars and one of the most luminous and massive red supergiants. It’s also one of the most luminous stars in the Milky Way. This Hubble Space Telescope image shows the huge nebula of material cast off by VY Canis Majoris.
