WR 134 Ring Nebula
Explanation: Made with narrowband filters, this
cosmic snapshot covers a field of view about the size of the full Moon within the boundaries of the constellation Cygnus. It highlights the bright edge of a ring-like nebula traced by the
glow of ionized sulfur, hydrogen, and oxygen gas. Embedded in
the region's interstellar clouds of gas and dust, the complex, glowing arcs are sections of bubbles or shells of material
swept up by the wind from
Wolf-Rayet star WR 134, brightest star near the center of the frame. Distance estimates put WR 134 about 6,000 light-years away, making the frame over 50 light-years across.
Shedding their outer envelopes 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. The stellar winds and final supernovae enrich the interstellar material with
heavy elements to be incorporated in
future generations of stars.
