Planetary Nebula


    This photograph of the coil-shaped Helix Nebula is one of the largest and most detailed celestial images ever made. The composite picture is a seamless blend of ultra-sharp images from NASA's Hubble Space Telescope combined with the wide view of the Mosaic Camera on the National Science Foundation's 0.9-meter telescope at Kitt Peak National Observatory near Tucson, Ariz.

    This image is NGC 6543 known as the Cat's Eye Nebula as it appears to the Chandra X-Ray Observatory and Hubble Telescope. A planetary nebula is a phase of stellar evolution that the sun should experience several billion years from now, when it expands to become a red giant and then sheds most of its outer layers, leaving behind a hot core that contracts to form a dense white dwarf star. This image was released October 10, 2012. (Photo by J. Kastner/NASA/CXC/RIT)

    In this image taken July 2, 2011 provided by NASA Thursday August 11, 2011 a giant cosmic necklace glows brightly in this Hubble Space Telescope image. The object, aptly named the Necklace Nebula, is a recently discovered planetary nebula, the glowing remains of an ordinary, Sun-like star. The Necklace Nebula is located 15,000 light-years away in the constellation Sagitta. (Photo by AP Photo/NASA)

    The interior of a planetary nebula glows in radient colors January 9, 2001 in an image taken by NASA's Chandra X-ray Observatory. Astronomers unexpectedly found a central star in the late stages of life emitting powerful X-ray energy. The X-ray observations of the Cat's Eye Nebula reveal a hot gas cloud around a bright star, which is shedding its material and is expected to collapse into a white dwarf in several million years.

    This intriguing picture from ESO’s Very Large Telescope shows the glowing green planetary nebula IC 1295 surrounding a dim and dying star. It is located about 3,300 light-years away in the constellation of Scutum (The Shield). The new image, released on April 10, 2013 by the European Southern Observatory, shows the planetary nebula IC 1295 like it has never been seen before. This picture, which ESO scientists dubbed [ghostly], marks the first time the nebula has been imaged such unprecedented detail. (Photo by ESO)

    A watery-looking nebula in deep space is being renamed after the sea creature it strongly resembles: a manatee. Manatees are huge mammals that average about 10 feet (3 meters) long and tend to weigh over 1,000 pounds (450 kilograms). These gentle giants propel themselves with flippers, and spend up to eight hours a day munching on sea plants. The photo shows the manatee nebula seemingly mimicking a trademark pose of the animal, which is often seen floating on its back, with flippers crossed over belly. The nebula W50 is the leftovers from a star that died in a supernova explosion about 20,000 years ago. Before it died, the giant star puffed out its outer gaseous layers, which now swirl in green-and-blue clouds around the dead hulk of the star, which has collapsed into a black hole.
