[00:00:02]Welcome to NASA's Astronomy Picture of the Day for May 22nd, 2026, titled The Nebulous Realm of WR 134.

[00:00:08]This cosmic snapshot covered a field of view over twice as wide as the full moon within the boundaries of the high-flying constellation Cygnus.

[00:00:15]Made using astronomical narrow-band filters, >> [music] >> the image highlighted the bright edge of a ring-like nebula traced by the glow of ionized hydrogen and oxygen gas.

[00:00:22]Embedded in the region's expanse of interstellar clouds, the complex glowing arcs were sections of shells of material swept up by the wind from Wolf-Rayet star WR 134, [music] the brightest star near image center.

[00:00:32]Distance estimates put WR 134 about 6,000 light-years away, >> [music] >> making this telescopic frame over 100 light-years across.

[00:00:39]Shedding their outer envelopes in powerful stellar winds, massive Wolf-Rayet stars had burned through their nuclear fuel at a prodigious rate and ended their final phase of massive star evolution in a spectacular supernova.

[00:00:49]Their stellar winds and final supernova explosion enriched the interstellar material with heavy elements to be incorporated in future generations of stars.
