10 stellar images of nebulae captured by NASA's Hubble Space Telescope

The star V830 Orionis shines on the cloud of material left over from its formation, here seen as the NGC 1999 reflection nebula.

The Helix Nebula is an example of a planetary nebula. It looks like a bubble or eye from Earth's point of view, the Helix is a trillion-mile-long tunnel of glowing gases.

The Orion Nebula is a picture book of star formation, from the massive, young stars shaping the nebula to the pillars of dense gas that may be the homes of budding stars.

The Crab Nebula is an expanding remnant of a star's supernova explosion. 

These opaque, dark knots of gas and dust called 'Bok globules' absorb light in the center of the nearby emission nebula and star-forming region, NGC 281.

This spectacular color panorama of the center the Orion nebula is one of the largest pictures ever assembled from individual images taken with NASA's Hubble Space Telescope.

This is an image of MyCn18, a young planetary nebula located about 8,000 light-years away, taken with the Wide Field and Planetary Camera 2 (WFPC2) aboard NASA's Hubble Space Telescope (HST).

These gigantic, tadpole-shaped objects are probably the result of a dying star's last gasps.

This Wide Field and Planetary Camera 2 image captures the infancy of the Stingray nebula (Hen-1357), the youngest known planetary nebula.
