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 ...

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

Decades of constant X-ray emission from the Helix Nebula’s white dwarf suggest debris from a Jupiter-sized planet steadily rains upon the star.

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), ...

A new photo snapped by the European Southern Observatory's Vista telescope shows the Helix Nebula, a planetary nebula located about 700 light-years from Earth in the constellation Aquarius.

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.

Helix's central star once resembled the Sun, but its outer layers of gas and dust sloughed off. The resulting planetary nebula, located some 700 light-years from Earth, is what telescopes now see.

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 ...
