Taken by Prosper Henry, 1885. This photograph of the Ring Nebula in the constellation Lyra shows but a three-degree section of the firmament, 1,956 light-years from earth. Once a star similar to our own sun, the nebula was formed when the star exploded, releasing gasses from its outer shell into space.
WR 134 Ring Nebula, 6,000 light-years away: Embedded in the region's interstellar clouds of gas and dust, the 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. 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.

NGC 6188 and NGC 6164 Image Credit & Copyright: Marco Lorenzi (Glittering Lights) The recent star formation itself was likely triggered by winds & supernova explosions, fr prev generations of massive stars, that swept up & compressed the molecular gas. Joining NGC 6188 on this cosmic canvas is rare emission nebula NGC 6164, also created by 1 of the region's massive O-type stars... The field of view spans abt 2 Full Moons, corresponding to 70 LYrs at the estimated distance of NGC 6188.
Finnish astrophotographer J-P Metsävainio observed IC 1396, making a gorgeous image of it. But he wasn’t satisfied just doing that. He’d been playing with making 3D images for some time, and decided this might be a good opportunity to make a model of the structure of the nebula, and then create an animated GIF of it.
