Astronomers have captured a striking new image of the Helix Nebula. A new picture, taken in infrared light, reveals strands of cold nebular gas that are invisible in images taken in visible light, as ...

In this image from NASA's Spitzer Space Telescope, "cometary knots" on the Helix Nebula show blue-green heads caused by excitation of their molecular material from shocks or ultraviolet radiation. An ...

In this space wallpaper, this colour-composite image of the Helix Nebula (NGC 7293) was created from images obtained using the the Wide Field Imager (WFI), an astronomical camera attached to the ...

A new image of the Helix planetary nebula shows arich background of distant galaxies. Astronomers used the European Southern Observatory's (ESO) La SillaObservatory in Chile to capture the view. The ...

What we’re looking at here is the swansong of a star much like our own Sun – that’s to say, a bog-standard, average-sized star. Not massive enough to go supernova when they run out of nuclear fuel, ...

The Helix Nebula, NGC 7293, is not only one of the most interesting and beautiful planetary nebulae; it is also one of the closest nebulae to Earth, at a distance of only 710 light years away. A new ...

A newly released image of the planetary nebula taken in infrared light brings into view what normally can't be seen in visible light. Anne Dujmovic was a senior editor at CNET. Her areas of focus ...

Our spectacular view of a nearby planetary nebula was captured by luck when the Hubble Space Telescope was turned around to avoid damage from a meteor storm – directly towards the Helix Nebula. While ...

The nearby Helix nebula just received the piercing infrared gaze of a giant telescope in Chile, and the resulting image reveals cold gas normally hidden among warmer star-lit material. Helix's central ...
