The Helix Nebula, located 650 light-years from Earth, has baffled scientists for decades. The planetary nebula was created by a dying star that shed its outer layers of gas, leaving behind a small ...

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 2 ...

The Helix Nebula, NGC 7293, lies about 700 light-years away in the constellation of Aquarius (the Water Bearer). It is one of the closest and most spectacular examples of a planetary nebula.

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 ...

The Helix Nebula is called a planetary nebula (confusingly, this name has nothing to do with planets but is a historical artifact arising from a mistake by scientists in the 19th century), ...

The Helix Nebula is located about 700 light-years from Earth, and its scale is absolutely enormous, clocking it at over four light-years across. To put that in perspective, ...

While the most stunning deep space image that has ever been taken is debatable (*cough* sh2–239 *cough*), in my not-so-humble opinion, this image of NGC 7293 (also known as the Helix nebula, or ...

The Helix nebula, located about 700 light-years away in the constellation Aquarius, was formed when a star much like our Sun died and sloughed off its skin, or outer layers.
