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…

JWST captured this new image of the Ring Nebula in unprecedented detail. Formed by a star throwing off its outer layers as it runs out of fuel, the Ring…

FAST FACT: The Hubble Space Telescope photographed what appeared to be Heaven in deep space in 1992, but after a flurry of excitement and wild speculations, “Paradise” was proved to be a simple cloud of dust and gasses left over after a star exploded 600 billion years ago. 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…

Hoag's Object: A Nearly Perfect Ring Nebula This question came to light in 1950 when astronomer Arthur Hoag chanced upon this unusual extragalactic...

[astronomy] In this composite image, visible-light observations by NASA's Hubble Space Telescope are combined with infrared data from the ground-based Large Binocular Telescope in Arizona to assemble a dramatic view of the Ring Nebula. The planetary nebula is about 2,000 light-years away in the constellation Lyra and measures roughly one light-year across. In the image, the blue color represents helium; the green, oxygen; and the red, hydrogen. ~Al. A.
