Helix Nebula - Wikipedia
The Helix Nebula is an example of a planetary nebula, formed by an intermediate to low-mass star, which sheds its outer layers near the end of its evolution. Gases from the star in the surrounding space appear, from Earth's perspective, a helix structure.

Star Death: Helix Nebula - ViewSpace
The dying star in this planetary nebula expelled its outer layers as gaseous wind, which are set aglow by its intense radiation. Thousands of thin filaments likely formed when hot stellar winds and radiation plowed into colder shells of gas and dust.
The Helix Nebula: Unraveling at the Seams | NASA Jet Propulsion ...
Oct 3, 2012 · This image from NASA's Spitzer and GALEX shows the Helix nebula, a dying star throwing a cosmic tantrum. In death, the star's dusty outer layers are unraveling into space, glowing from the intense UV radiation being pumped out by the hot stellar core.
NGC 7293, the Helix Nebula - NASA Jet Propulsion Laboratory …
May 16, 2012 · NGC 7293, better known as the Helix nebula, displays its ultraviolet glow courtesy of NASA's Galaxy Evolution Explorer (GALEX). The Helix is the nearest example of a planetary nebula, which is the eventual fate of a star, like our own Sun, as it approaches the end of its life.
NASA SVS | The Helix Nebula from Hubble - NASA Scientific …
Feb 27, 2017 · This Hubble Space Telescope image showcases the details of the Helix Nebula, one of the nearest planetary nebulae to Earth. A planetary nebula forms when a medium-sized star undergoes the final stages of nuclear fusion in its core and casts of its outer layers of gas.
The Helix Nebula: a Gaseous Envelope Expelled By a Dying Star
Dec 16, 2004 · The Helix is a planetary nebula, the glowing gaseous envelope expelled by a dying, sun-like star. The Helix resembles a simple doughnut as seen from Earth. But looks can be deceiving. New evidence suggests that the Helix consists of two gaseous disks nearly perpendicular to each other.
The Helix Nebula: Bigger in Death than Life
Oct 3, 2012 · In death, the star's dusty outer layers are unraveling into space, glowing from the intense ultraviolet radiation being pumped out by the hot stellar core. This object, called the Helix nebula, lies 650 light-years away in the constellation of Aquarius.
Dust and the Helix Nebula - NASA
Mar 23, 2008 · This eerie Spitzer Space Telescope image shows infrared radiation from the well-studied Helix Nebula (NGC 7293), which is a mere 700 light-years away in the constellation Aquarius. Dust makes this cosmic eye look red.
APOD: 2021 October 14 - NGC 7293: The Helix Nebula
Its last few thousand years have produced the Helix Nebula (NGC 7293), a well studied and nearby example of a Planetary Nebula, typical of this final phase of stellar evolution. A total of 90 hours of exposure time have gone in to creating this expansive view of the nebula.
