15 de sept. de 2003 · The Helix is a tube-shaped planetary nebula, an expanding shell of gas around a dying star. This Hubble Space Telescope image stares straight into the barrel of the tube. The lithograph's text explains the Helix Nebula's appearance and gives general information on planetary nebula formation.
Helixnebel. Der Helixnebel (auch NGC 7293 oder Auge Gottes) ist ein Planetarischer Nebel im Sternbild Wassermann mit einer Helligkeit von 6,30 mag und einem scheinbaren Durchmesser von 16 × 28 Winkelminuten. Er wurde im Jahr 1823 von dem deutschen Astronomen Karl Ludwig Harding entdeckt. Der Helixnebel ist mit einer Entfernung von etwa 650 ...
16 de may. de 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. As it runs out of fuel, the star expels its outer envelope of gas ...
The Helix Nebula is the closest example of a planetary nebula created at the end of the life of a Sun-like star. The outer gasses of the star expelled into space appear from our vantage point as if we are looking down a helix. The remnant central stellar core, destined to become a white dwarf star, glows in light so energetic it causes the ...
23 de sept. de 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. With an apparent magnitude of 7.6 and an apparent size of 25 arcminutes, the nebula is visible in binoculars and easily observed ...
21 de mar. de 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. Explore the science along with the scenery – Image Tours show Hubble pictures through an astronomer's eyes, pinpointing and explaining key features to add understanding to ...
Helix Nebula Detail. This cropped version of the Helix Nebula mosaic shows cometary-filaments embedded along a portion of the inner rim of the nebula's red and blue gas ring. At a distance of 650 light-years, the Helix is one of the nearest planetary nebulae to Earth. The composite picture is a seamless blend of ultra-sharp NASA/ ESA Hubble ...
