The Helix Nebula (NGC 7293) is a challenging stargazing target for amateur astronomers. It is one of the closest planetary nebulas -- a type of nebula formed from gas ejected by a dying sunlike star.
A new portrait of the Helix Nebula, created by the infrared Spitzer Space Telescope, has be...

It looks like a soap bubble or perhaps even a camera fault, but the image at right is a newly discovered planetary nebula. Planetary nebulae, which got their name after being misidentified by early astronomers, are formed when an ageing star weighing up to eight times the mass of the sun ejects its out...

The colourful, intricate shapes in these NASA Hubble Space Telescope images reveal how the glowing gas ejected by dying Sun-like stars evolves dramatically over time. These gaseous clouds, called planetary nebulae, are created when stars in the last stages of life cast off their outer layers of m...
