Ring nebula

Messier 57 - The Ring Nebula Credit: NASA/ESA HST, Spitzer ST, Giuseppe Donatiello RA: 283,387° Dec: 33,026 The Ring Nebula (Messier 57 or NGC 6720) is a planetary nebula in Lyra and it is illuminated by a central white dwarf or planetary nebula nucleus (PNN) of 15.75 visual magnitude. All the interior parts of this nebula have a blue-green tinge that is caused by the doubly ionized oxygen emission lines at 495.7 and 500.7 nm. In the outer region of the ring, part of the reddish hue is…

THE DISCOVERY of pearly gates, temples and streets of gold on the otherwise barren and lifeless surface of Mars has stunned scientists and clergymen alike, many of whom believe the items are dazzling new proof that Heaven…
