Bubble Nebula

Space enthusiasts are sharing details about the Bubble Nebula, an emission nebula catalogued as NGC 7635 in the constellation Cassiopeia. Located near the open cluster Messier 52, it gets its distinctive shape from the stellar wind of a massive, hot young central star. The object, also listed as Sharpless 162 or Caldwell 11, is being celebrated as one of the more striking sights in the night sky.

Astronomy enthusiasts are sharing images and details of Sh2-308, the nebula nicknamed the Dolphin Nebula. Located about 5,000 light-years away in the constellation Canis Major, the vast cosmic bubble spans roughly 60 light-years and was shaped by the intense radiation and stellar winds of a massive Wolf-Rayet star. Posts highlight its striking shape and the dramatic process by which a dying giant carves such an enormous structure into surrounding gas.

An amateur astronomer has published a new astrophotograph of NGC 7635, the Bubble Nebula, together with the open cluster M52 in Cassiopeia. The image was taken in HOO bicolor from 240 exposures of 60 seconds each in hydrogen-alpha and oxygen-III, using a SkyWatcher 254/1000 telescope, QHY163M camera and EQ6-R Pro mount with guiding. Astronomy communities are sharing the result as an example of what dedicated home equipment can capture.
