http://www.spacetelescope.org/images/heic0703a/ This image of NGC 2440 shows the colourful "last hurrah" of a star like our Sun. The star is ending its life by casting off its outer layers of gas, which formed a cocoon around the star's remaining core. Ultraviolet light from the dying star makes the material glow. The burned-out star, called a white dwarf, is the white dot in the centre.

The #HelixNebula: Unraveling at the Seams | A dying star is throwing a cosmic tantrum in this combined image from NASA's Spitzer Space Telescope and the Galaxy Evolution Explorer (GALEX), which NASA has lent to the California Institute of Technology in Pasadena. In death, the star's dusty outer layers are unraveling into space, glowing from the intense ultraviolet radiation being pumped out by the hot stellar core.

Hubble sees the beautiful demises of a dying star This image, taken by the NASA/ESA Hubble Space Telescope, shows the colorful "last hurrah" of a star like our sun.

Hubble at 25: the best images from the space telescope - in pictures

Hubble at 25: the best images from the space telescope - in pictures The star cluster Pismis 24 lies in the core of the large emission nebula NGC 6357. The bluest stars are the youngest, and part of the nebula is ionised by them. The ultraviolet radiation from the blazing stars heats the gas surrounding the cluster.

A GALEX ultraviolet image of the interacting galaxies M81 and M82, which lie 12 million light-years away in the constellation Ursa Major. The gravity from each galaxy dramatically affected the other during their last close encounter, 200 million years ago. Gas density waves rippling around M81 make it a grand design spiral. M82 is undergoing a starburst at its core, creating glowing fingers of hydrogen.

The Glowing Eye of NGC 6751 - Hubble spied a giant celestial "eye" glowing in the constellation Aquila. The nebula is a cloud of gas ejected several thousand yrs ago from the hot star visible in its center. Planetary nebulae are shells of gas thrown off by Sun-like stars nearing the ends of their lives. The star's loss of its outer gaseous layers exposes the hot stellar core, whose strong ultraviolet radiation then causes the ejected gas to fluoresce as the planetary nebula.
