WR 134 is a variable Wolf-Rayet star located around 6,000 light years away from Earth in the constellation of Cygnus, surrounded by a faint bubble nebula blown by the intense radiation and fast wind from the star. It is five times the radius of the sun and over 400,000 times as luminous as the Sun. A Wolf-Rayet star is basically a pre-supernova, its high stellar winds pushing the interstellar gas and dust into a roughly spherical shape which in this case is rather asymmetrical, with the one side more pronounced.
The data was captured on multiple nights last week and total capture time is around 25 hours...
