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.
Oct 4, 2012 · This object, called the Helix nebula, lies 650 light-years away, in the constellation of Aquarius. Also known by the catalog number NGC 7293, it is a typical example of a class of objects called planetary nebulae.
Sep 3, 2020 · This Helix Nebula images contains infrared data from NASA’s Spitzer Space Telescope (green and red), optical light from Hubble (orange and blue), ultraviolet from NASA’s Galaxy Evolution Explorer (cyan), and Chandra’s X-rays (appearing as white) showing the white dwarf star that formed in the center of the nebula.
Sep 23, 2021 · The Helix Nebula (NGC 7293) is a bright, large planetary nebula located 650 light years from Earth in the constellation Aquarius. It is one of the closest planetary nebulae to Earth, as well as one of the brightest.
The Helix Nebula is one of the closest planetary nebulae to Earth, giving scientists a detailed look at this type of stellar demise. Comet-like tendrils cluster along the inner rim of the nebula’s reddish outer gas ring.
Quick Facts: Helix Nebula. Also known as: NGC 7293. Type of object: Planetary nebula. Distance from Earth: 700 light-years.
Combining narrow band image data from emission lines of hydrogen atoms in red and oxygen atoms in blue-green hues, it shows remarkable details of the Helix's brighter inner region about 3 light-years across. The white dot at the Helix's center is this Planetary Nebula's hot, central star.
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.
Mar 21, 2006 · The Helix Nebula, a favorite target for amateur astronomers, is one of the closest planetary nebulae to Earth. Planetary nebulae are shells of gas expelled by dying stars.
May 16, 2012 · NGC 7293, better known as the Helix nebula, displays its ultraviolet glow courtesy of NASA's 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.
