Planetary nebula M57 (NGC 6720) in Lyra - The Ring nebula (M57) in Lyra - The planetary nebula of Lyra (M57) is located about 2000 years - light from Earth. With a magnitude of 9.0, this nebula is easily observed with a small telescope. A planetary nebula is a gas shell from a small late-life star whose heart collapsed to become a white dwarf and expelled the outer layers of its matter. The Ring Nebula, M57, is the most famous example of a planetary nebula. Located about 2,000 light years away, it has an apparent diameter of 1 arc minute and a real diameter of about one light year. At magnitude 9.0 its high surface brightness makes it an easy object, even from the city and even with small telescopes. Despite their name, planetary nebulae have nothing to do with planets. They were named originally because their discoverers observed them visually and they did not appear as stellar point sources, but rather as small diffuse objects that resembled the outer planets in our solar system such

Nebula Sh2 - 106 in the Swan - Sh2 - 106 nebula in Cygnus - Sharpless 106 (Sh2 - 106) is a star-forming region in the constellation Swan. Image obtained by the Hubble Space Telescope (HST). The bipolar star - forming region, called Sharpless 2 - 106, or S106 for short, looks like a soaring, celestial snow angel. The outstretched “” wings”” of the nebula record the contrasting imprint of heat and motion against the backdrop of a colder medium. Twin lobes of super - hot gas, glowing blue in this image, stretch outward from the central star. This hot gas creates the “” wings”” of our angel. A ring of dust and gas orbiting the star acts like a belt, cinching the expanding nebula into an “” hourglass”” shape

Nebula IC 2220 in the Carene - A mass - loss star in IC 2220 - This nebula is illuminated by a giant red star, the star HD 65670. Image obtained by Siding Spring's 3.9m telescope. The bright, supergiant star at the centre of this nebula is known only by its catalog designation, HD 65750. The nebulosity around the star is the result of light reflected by dust surrounding it. The dust is thought to consist mainly of particles of silica condensed from material which the star is losing from its distended surface at a fairly steady rate. The rate of mass loss is much higher than in normal stars and is sufficient to produce the reflection nebula IC 2220. The stellar nature of the central object is revealed by the four diffraction spikes extending from it. These are artifacts due to structures within the telescope. The light from the star has also produced the annular halation ring (a photographic artefact) that ornaments the nebula. These features, real or otherwise, have provoked the name '

Detail of the Tarantula nebula (NGC 2070) in the Dorado - Detail of the Tarentula nebula in Dorado - Image of a detail of the Tarantula nebula obtained in December 2001 with the WFI instrument of the ESO/MPG 2.2 telescope - m at the La Silla Observatory. The Tarantula Nebula (or 30 Dorada) is the largest star-forming region of the Great Magellan Cloud, a galaxy adjacent to ours. It is located 170,000 light years ago in the constellation Dorado (southern hemisphere). This image shows the turbulent region around the ring - shaped nebula DEM L 299 in the Large Magellanic Cloud, a satellite galaxy of the Milky Way system. It was produced by combining three monochromatic images obtained in December 2001 with the Wide - Field - Imager (WFI) at the ESO/MPG 2.2 - m telescope at the La Silla Observatory. North is up and East is left. The coloured rings seen near some of the brighter stars in the field result from light reflections in the telescope optics. The Tarantula Nebula is one of the most

Planetary nebula M57 (NGC 6720) in Lyra - The Ring nebula M57 in Lyra - The planetary nebula of Lyra (M57) is located about 2000 years - light from Earth. A planetary nebula is a gas shell from a small late-life star whose heart collapsed to become a white dwarf and expelled the outer layers of its matter. Image obtained by the Hubble Space Telescope. This close - up, visible - light view by Nasa's Hubble Space Telescope reveals new details of the Ring Nebula. The object is tilted towards Earth so that astronomers see the ring face - on. The Hubble observations reveal that the nebula's shape is more complicated than astronomers thought. The blue gas in the nebula's center is actually a football - shaped structure that pierces the red doughnut - shaped material. Hubble also uncovers the detailed structure of the dark, irregular knots of dense gas embedded along the inner rim of the ring. The knots look like spokes in a bicycle.

Planetary nebula NGC 5189 in the Fly - NGC 5189 - Planetary nebula in Musca - This nebula is located about 3000 light years from Earth in the southern constellation of Fly. Image obtained by the Gemini telescope. NGC 5189 is a planetary nebula. At the end of its life, a star with a mass less than eight times that of the Sun will blow its outer layers away, giving rise to a planetary nebula. Some of these stellar puffballs are almost round, resembling huge soap bubbles or giant planets (hence the name), but others, such as NGC 5189 are more intricate. In particular, this planetary nebula exhibits a curious S” - shaped profile, with a central bar that is most likely the projection of an inner ring of gas discharged by the star, seen edge on.

The nebula itself appears quite small at a little over an arc minute in diameter, while its central star is a magnitude 14 white dwarf. This object is unusual because those planetaries that are not bipolar are more or less spherical shells of material thrown off by the central star as it undergoes an internal rearrangement. We often see them as thick annuli because we look through a greater thickness at the edge of the shell.

The wind of material propelled by radiation from the hot central star has created enough pressure to blow open holes in the ends of the bubbles, allowing gas to escape.

Planetary nebula NGC 6369 in Ophiuchus/HST - NGC 6369 is known to amateur astronomers as the “” Little Ghost Nebula,”” because it appears as a small, ghostly cloud surrounding the faint, dying central star.

When a star with a mass similar to that of our own Sun nears the end of its lifetime, it expands in size to become a red giant. The red - giant stage ends when the star expels its outer layers into space, producing a faintly glowing nebula. Astronomers call such an object a planetary nebula, because its round shape resembles that of a planet when viewed with a small telescope.

This picture has been composed from three separate images taken in the light of ionized nitrogen (represented by red), hydrogen (green), and doubly - ionized oxygen (blue). The results are of great interest because they shed new light on the poorly understood ejection of stellar matter which accompanies the slow death of Sun - like stars. According to one theory for the formation of planetary nebulae, the hourglass shape is produced by the expansion of a fast stellar wind within a slowly expanding cloud which is more dense near its equator than near its poles.

Observations suggest the star ejected its mass in a series of pulses at 1,500 - year inte

Planetary nebula NGC 6543 dans le Dragon/HST - The nebula, formally cataloged NGC 6543 was one of the first planetary nebulae to be discovered; it is one of the most complex such nebulae seen in space. A planetary nebula forms when Sun - like stars gently eject their outer gaseous layers that form bright nebulae with amazing and confounding shapes. In 1994, Hubble first revealed NGC 6543's surprisingly intricate structures, including concentric gas shells, jets of high - speed gas, and unusual shock - induced knots of gas. As if the Cat's Eye itself isn't spectacular enough, this new image taken with Hubble's Advanced Camera for Surveys (ACS) reveals the full beauty of a bull's eye pattern of eleven or even more concentric rings, or shells, around the Cat's Eye. Each 'ring' is actually the edge of a spherical bubble seen projected onto the sky - - that's why it appears bright along its outer edge.
