The Dumbbell Nebula ... also known as Messier 27 and the Apple Core Nebula. May 16, 2020
This planetary nebula found in the constellation of Vulpecula is about 1,360 light-years away. It formed as the star ended its life in a massive explosion about 9,800 years ago. The remnant of the star is now a very hot white dwarf which can be seen as a small blue star in the center. The radiation of this dwarf continues to illuminate the emission cloud of the gas particles from the explosion. The Dumbbell nebula can be easily seen in binoculars and small telescopes in a dark sky, just above the small constellation of Sagitta. M 27 is best viewed during the late spring and summer months and it is located within the 'Summer Trianagle' of the 3 bright stars of Vega, Deneb, and Altair. On this date, it is medium high in the ENE shortly after midnight. The final exposure time for this image was 2hr 50mn
