M57 – The Ring Nebula

lyrehubble

From — Charles Messier’s Catalog of Nebulae and Star Clusters:
18h 45m 21s (281d 20′ 08″) +32d 46′ 03″(January 31, 1779) `A cluster of light between Gamma & Beta Lyrae, discovered when looking for the Comet of 1779, which has passed it very close: it seems that this patch of light, which is round, must be composed of very small stars: with the best telescopes it is impossible to distinguish them; there stays only a suspicion that they are there. M. Messier reported this patch of light on the Chart of the Comet of 1779. M. Darquier, at Toulouse, discovered it when observing the same comet, and he reports: “Nebula between gamma and beta Lyrae; it is very dull, but perfectly outlined; it is as large as Jupiter & resembles a planet which is fading”.’

The Ring Nebula or M57 is located 2,300 light-years / 0.7 kpc away in the constellation Lyra.  This image was taken by the WFPC2 camera onboard the Hubble Space Telescope in 1998.
