NASA. LARGE FORMAT. Superb photograph of the famous Ring nebula in eastern Lyra. It is illuminated by a central white dwarf or planetary nebula nucleus (PNN) of visual magnitude 15.75. All the inner parts of this nebula have a blue-green hue, caused by the emission lines of doubly ionized oxygen at 495.7 and 500.7 nm. In the outer region of the ring, part of the reddish hue is due to hydrogen emission at 656.3 nm. M57 is an example of the class of planetary nebulae known as bipolar nebulae. In this composition lies all the resolving power of the Hubble Space Telescope.period chromogenic print. Numbering on front. Legend on back label. 40.6 x 40.6CM with margins.
