WASHINGTON, May 23, 2013 /PRNewswire-USNewswire/ -- The Ring Nebula's distinctive shape makes it a popular illustration for astronomy books. But new observations by NASA's Hubble Space Telescope of the glowing gas shroud around an old, dying, sun-like star reveal a new twist. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) "The nebula is not like a bagel, but rather, it's like a jelly doughnut, because it's filled with material in the middle," said C. Robert O'Dell of...
Lee Rannals for redOrbit.com – Your Universe Online NASA and the European Space Agency (ESA) have released a new Hubble Space Telescope image of the planetary nebula NGC 5189. In the essence of the Christmas spirit, ESA describes the cosmic structure of the eruption as a "giant and brightly colored ribbon in space." The structure visible within NGC 5189 is particularly dramatic, and the space agencies said the image is the most detailed yet image of this object. Planetary...
Lee Rannals for redOrbit.com - Your Universe Online Astronomers recently found evidence for a dying star coming back to life, giving insight into what may be the fate of our own Solar System in a few billion years. The picture released by the European Space Agency (ESA) is of the planetary nebula Abell 30, located 5,500 light-years away from Earth. A planetary nebula is the often-concentric shells of stellar material cast into space by dying stars. Astronomers in the 18th century...
[ Video 1 ] | [ Video 2 ] | Video 3 ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers have discovered a pair of stars orbiting each other at the center of a remarkable example of a planetary nebula. The latest find confirms a theory about what controls the spectacular and symmetric appearance of the material flung out into space. Planetary nebulae are glowing shells of gas around white dwarfs, and Fleming 1 is considered a great example that has strikingly...
April Flowers for redOrbit.com - Your Universe Online An international team of astronomers using NASA's Chandra X-ray Observatory has created a sweeping new survey of dying stars – or planetary nebula – in the neighborhood of the Sun. The resulting X-ray images shed light on the violent "end game" of a Sun-like star's life. Led by Joel Kastner from the Rochester Institute of Technology (RIT), the team won seven days of observation time with Chandra in 2011-2012 to survey and image...
[ Watch the Video ] ESO’s VISTA telescope, at the Paranal Observatory in Chile, has captured a striking new image of the Helix Nebula. This picture, taken in infrared light, reveals strands of cold nebular gas that are invisible in images taken in visible light, as well as bringing to light a rich background of stars and galaxies. The Helix Nebula is one of the closest and most remarkable examples of a planetary nebula [1]. It lies in the constellation of Aquarius (The Water Bearer),...
Answers about the ultimate fate of our planet and solar system may have been discovered by a team of researchers that could also help resolve a decades-old debate about the impact of stellar companions have on the formation and structure of planetary nebulae, UPI is reporting. The team of astronomers including Associate Professor Orsola De Marco from Sydney's Macquarie University, announced the existence of the planetary nebula named Kronberger 61, discovered by an amateur astronomer.The...
A new image from NASA's Wide-field Infrared Survey Explorer shows what looks like a glowing jellyfish floating at the bottom of a dark, speckled sea. In reality, this critter belongs to the cosmos -- it's a dying star surrounded by fluorescing gas and two very unusual rings."I am reminded of the jellyfish exhibition at the Monterey Bay Aquarium -- beautiful things floating in water, except this one is in space," said Edward (Ned) Wright, the principal investigator of the WISE mission at UCLA,...
Today ESO has released a dramatic new image of NGC 346, the brightest star-forming region in our neighboring galaxy, the Small Magellanic Cloud, 210 000 light-years away towards the constellation of Tucana (the Toucan). The light, wind and heat given off by massive stars have dispersed the glowing gas within and around this star cluster, forming a surrounding wispy nebular structure that looks like a cobweb. NGC 346, like other beautiful astronomical scenes, is a work in progress, and changes...
A team of scientists in Australia and the United States, led by Associate Professor Miroslav Filipović from the University of Western Sydney, have discovered a new class of object which they call "Super Planetary Nebulae." They report their work in the journal Monthly Notices of the Royal Astronomical Society.Planetary nebulae are shells of gas and dust expelled by stars near the end of their lives and are typically seen around stars comparable or smaller in size than the Sun.The team...

Puppis Constellation -- Containing the brightest star visible on earth, the constellation of Canis Major is one of the few constellations in the heavens which resembles what it is supposed to be: a large dog. Its neighbor, Puppis, on the other hand, boasts no bright stars, and is difficult at best for even seasoned observers to identify. Stellar beacons notwithstanding, both of these constellations are rich in open clusters, as they lie along the winter Milky Way. Several...
Planetary Nebula -- A planetary nebula is an astronomical object that usually appears nebulous and disk-like in low-resolution observations. Because of this appearance, similar to the appearance of planets in early observations, the "planetary" adjective was attached and has since been retained for historical consistency. According to current observations and models, planetary nebulae in fact have little to do with planets. Instead, as a small star (less than a few times the mass...
Nebula -- in astronomy, observed manifestation of a collection of highly rarefied gas and dust in interstellar space. Prior to the 1960s this term was also applied to bodies later discovered to be galaxies, e.g., the so-called Great Nebula in the constellation Andromeda. In 1864, William Huggins confirmed William Herschel's conclusion that nebulae are not swarms of stars by determining that the spectra of nebulae are made of bright lines characteristic of radiating gases. Diffuse...
Saturn Nebula -- The layers of the Saturn Nebula give a complex picture of how this planetary nebula was created. The above picture, taken in April 1996 and released last week, allows a better understanding of the mysterious process that transformed a low-mass star into a white dwarf star. A computer model indicates that the central star of NGC 7009 first expelled the green gas that now appears barrel shaped. This green gas now confines stellar winds flowing from the central star,...
Rosette Nebula -- Discovered by John Flamsteed about 1690. The Rosetta Nebula is a vast cloud of dust and gas, extending over an area of more than 1 degree across, or about 5 times the area covered by the full moon. Its parts have been assigned different NGC numbers: 2237, 2238, 2239, and 2246. Within the nebula, open star cluster NGC 2244 is situated, consisted of the young stars which recently formed from the nebula's material, and the brightest of which make the nebula shine by...
