Summary
[edit]
| Description |
English: The Ring Nebula (also cataloged as Messier 57, M57 and NGC 6720) is a planetary nebula in the northern constellation of Lyra. The tiny white dot in the center of the nebula is the star’s hot core, called a white dwarf. M57 is about 2,000 light-years away in the constellation Lyra, and is best observed during August. Discovered by the French astronomer Antoine Darquier de Pellepoix in 1779, the Ring Nebula has an apparent magnitude of 8.8. It is easy to find, as it lies about halfway between the two 3rd -magnitude stars “Sheliak” and “Sulafat” which form the bottom of Lyra’s lyre; however, it requires a moderately-sized telescope to see its beautiful ring-like details.
