WR 134 is a variableWolf-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, but due to a temperature over 63,000 K it is 400,000 times as luminous as the Sun.
Embedded in the region's interstellar clouds of gas and dust, the complex, bright arcs are the sections of bubbles or shells of windblown material from the Wolf-Rayet star WR 134, the brightest star near the center of the galaxy. plot. Distance estimates place WR 134 at about 6,000 light-years away, making the frame more than 50 light-years across. This region lies just about 2 degrees south of NGC 6888, the Crescent Nebula. Shedding their outer shells in powerful stellar winds, massive Wolf-Rayet stars have burned through their nuclear fuel at a prodigious rate and end this final phase of massive star evolution in a spectacular supernova explosion. Stellar winds and final supernovae enrich the interstellar medium with heavy elements that will be incorporated into future generations of stars.
For this image I combine OIII with Ha.
