PIX4623200: Planetary nebula NGC 6302 in Scorpio - Planetary nebula NGC 6302 in Scorpius - NGC 6302 is a planetary nebula located about 4000 years from Earth. In the center of the nebula, an extremely hot dying star. Image obtained by the Hubble Space Telescope with the new WFC 3 (Wide Field Camera 3) camera, July 27, 2009. A dying star that was once about five times the mass of the Sun is at the center of this nebula. It has ejected its envelope of gases and is now unleashing a stream of ultraviolet radiation that is making the cast - off material glow. This object is an example of a planetary nebula, so - named because many of them have a round appearance resembling that of a planet when viewed through a small telescope. The Wide Field Camera 3 (WFC3), a new camera aboard Nasa's Hubble Space Telescope, snapped this image of the planetary nebula, catalogued as NGC 6302, but more popularly called the Bug Nebula or the Butterfly Nebula. WFC3 was installed by NASA astronauts in May 2009, during the servicing mission to upgrade and repair the 19 - year - old Hubble telescope. NGC 6302 lies within our Milky Way galaxy, roughly 3,800 light - years away in the constellation Scorpius. The glowing gas is the star's outer layers, expelled over about 2,200 years. The “” butterfly”” stretches for more than two light - years, which is about half the distance from the Sun to the nearest star, Alpha Centauri. The central star itself cannot be seen, because it is hidden within a doughnut - shaped ring of dust, which appears as a dark band pinching the nebula in the center. The thick dust belt constricts the star's outflow, creating the classic “” bipolar”” or hourglass shape displayed by some planetary nebulae. The star's surface temperature is estimated to be about 400,000 degrees Fahrenheit, making it one of the hottest known stars in our galaxy. Spectroscopic observations made with ground - based telescopes show that the gas is roughly 36,000 d / Bridgeman Images
PIX4623214: Planetary nebula NGC 6537 in Sagittarius - Hubble observations have revealed huge waves sculpted in the Red Spider nebula. This warm and windy planetary nebula harbours one of the hottest stars in the Universe and its powerful stellar winds generate waves 100 billion kilometers high - intimidating for even the bravest space surfers. The Red Spider Nebula, NGC 6537, is a striking 'butterfly' or bipolar (two - lobed) planetary nebula. Planetary nebulae are the glowing embers of ordinary stars, such as our Sun. At the end of their lives these stars expel most of their material into space, often forming a two - lobed structure as in the case of the Red Spider. These waves are driven by stellar winds radiating from the hot central star, much as a wind passing over a lake can generate waves on the water. The waves reach peaks 100 billion kilometers high and must have been produced by a powerful wind blowing with a speed of 2000 - 4500 kilometers per second (about 7 - 16 million km/hr). The waves themselves move outwards at a slower rate of 300 km/s (about 1 million km/hr). To add to these challenging climatic conditions, this nebula is not only windy, but also hot. The temperature of the gas waves is a scorching 10,000 K Detailed investigations of the Hubble image have shown that the central white dwarf, the remaining compact core of the original star, must have a temperature of at least half a million degrees, making it one of the hottest stars known. It is so hot that it is invisible to Hubble's eye and emits primarily in X - rays. The waves are generated by supersonic shocks formed when the local gas is compressed and heated in front of the rapidly expanding lobes. Atoms caught in the shocks radiate the visible light seen in this image. The process appears to have been underway long enough to make the edges of the lobe walls look as if they have started to fracture into wave crests. The Red Spider Nebula is located about 3000 light - years away in the constell / Bridgeman Images

PIX4623330: 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 (HST). The Hubble Space Telescope has captured the sharpest view yet of M57, the Ring Nebula in Lyra, which is the most famous of all planetary nebulae. In this image, the telescope has looked down a tunnel of gas cast off by a dying star thousands of years ago. This photo reveals elongated dark clumps of material embedded in the gas at the edge of the nebula, and the dying central star floating in a blue haze of hot gas. The nebula is about a light - year in diameter, and is located some 2,000 light - years from Earth in the direction of the constellation Lyra / Bridgeman Images

PIX4623563: Helix planetary nebula (NGC 7293) in Aquarius by HST - Helice's planetary nebula, located in Aquarius, is one of the closest to Earth (650 years - light) and is also one of the most extended. Its apparent diameter is about half of the full moon. It was obtained from two clicks taken by the ACS panoramic camera of the Hubble Space Telescope and from the 90 cm telescope of Kitt Peak in Arizona. It reveals unseen details of the filamentary structure of the blue and red gas ring that surrounds the starred star (in the centre of the nebula). In the center of the image, the star that expelled its material became a white dwarf / Bridgeman Images
PIX4623642: Planetary nebula Helix (NGC 7293) in Aquarius - Planetary nebula Helix (NGC 7293) - This nebula is located 690 years - light from Earth. Image obtained by Siding Spring's 3.9m telescope This faint object is the nearest planetary nebula to the Sun and on deep photographs has a diameter of about half a degree - - the same apparent size as the Sun in the sky. The AAT colour picture shows the brighter parts of the nebula, revealing various ionization levels within the shell of matter ejected from the central star. The greenish middle portion is evidence of excited oxygen atoms, while the outer red is predominantly light from nitrogen and hydrogen. The smallest of the radial blobs inside the red shell are about 150 astronomical units across (150 times the Earth - Sun distance) and they give this beautiful object its alternative name, the Sunflower Nebula. The Helix is about 400 light years away, or about 100 times more distant than the nearest stars / Bridgeman Images

PIX4627116: Le Soleil vu by STEREO on 16/08/2008 - Solar activity seen by STEREO spacecraft on august 16 2008 - Protuberances observed by one of the STEREO satellites on 16 August 2008. A STEREO spacecraft observed several solar prominences rise and gyrate above the Sun over a two - day period (Aug. 15 - 16, 2008), with the largest one arcing a distance at least equal to 30 Earth diameters. They are spread out with one in each quadrant. Magnetic forces control solar prominences that rise above the Sun's surface. The prominences were seen in the 304 Angstroms wavelength of ultraviolet light. The material observed is actually ionized Helium at about 60,000 degrees. Prominences are relatively cool clouds of gas suspended above the Sun and controlled by magnetic forces. They can last from hours to months, but most usually remain for just a few days / Bridgeman Images

The STEREO spacecraft observed this visually stunning prominence eruption on Sept. 29, 2008, in the 304 angstrom wavelength of extreme UV light. Prominences are relatively cool clouds of gas suspended above the sun and controlled by magnetic forces. The prominence rose and cascaded to the right over several hours, appearing something like a flag unfurling, as it broke apart and headed into space. The prominence is composed of ionized Helium that is about 60,000 degrees Kelvin / Bridgeman Images

PIX4627176: Le Soleil vu by SDO on December 6, 2010 - The Sun seen by SDO. December 6, 2010 - Le Soleil vu en ultraviolet by SDO (Solar Dynamics Observatory) on December 6, 2010. It shows a gas filament of nearly a million miles breaking. A very long solar filament that had been snaking around the Sun erupted on December 6, 2010 with a flourish. Nasa's Solar Dynamics Observatory (SDO) caught the action in dramatic detail in extreme ultraviolet light of Helium. It had been almost a million km long ((about half a solar radius) and a prominent feature on the Sun visible over two weeks ago before it rotated out of view. Filaments are elongated clouds of cooler gases suspended above the Sun by magnetic forces. They are rather unstable and often break away from the Sun / Bridgeman Images
PIX4627193: Le Soleil eclipse partially par la Terre - The Sun cut by the Earth seen by SDO - Le Soleil vu en ultraviolet by SDO (Solar Dynamics Observatory) on March 29, 2011 (07:14:57 UT). In this image the Sun is cut by the Earth because at the time of shooting, the SDO satellite was passing behind the Earth. Differences in the density of the Earth's atmosphere block light inevenly, which explains why the Sun does not appear to cut evenly. Nasa's Solar Dynamics Observatory (SDO) observes a partial solar eclipse. Twice a year, the SDO enters an eclipse season where the spacecraft slips behind Earth for up to 72 minutes a day.
