Planetary Nebulae Observed Releasing Water-Building Molecules
2014-06-17 11:19:05

Brett Smith for redOrbit.com - Your Universe Online The region in space around a planetary nebula is filled with harsh radiation. Yet despite this hostile environment – the area is seeded with a molecule essential to the formation of water. According to two new studies -- "Herschel Planetary Nebula Survey" and "Herschel spectral mapping of the Helix nebula" -- based on observations from the European Space Agency’s Herschel Observatory, harsh radiation around a planetary nebula does...

Celestial Diamond Ring Created By Chance Meeting
2014-04-09 11:35:16

[ Watch The Video: Zooming In On The Planetary Nebula Abell 33 ] ESO Astronomers using ESO’s Very Large Telescope in Chile have captured this eye-catching image of planetary nebula PN A66 33 — usually known as Abell 33. Created when an aging star blew off its outer layers, this beautiful blue bubble is, by chance, aligned with a foreground star, and bears an uncanny resemblance to a diamond engagement ring. This cosmic gem is unusually symmetric, appearing to be almost circular...

Monkey Head Nebula
2014-03-17 14:27:53

NASA/ESA Hubble Space Telescope To celebrate its 24th year in orbit, the NASA/ESA Hubble Space Telescope has released a beautiful new image of part of NGC 2174, also known as the Monkey Head Nebula. This colorful region is filled with young stars embedded within bright wisps of cosmic gas and dust. NGC 2174 lies about 6400 light-years away in the constellation of Orion (The Hunter). Hubble previously viewed this part of the sky back in 2001, creating a stunning image released in 2011,...

Ghostly Trio Imaged Using NASA's Spitzer Space Telescope
2013-10-29 10:12:36

NASA's Jet Propulsion Laboratory In the spirit of Halloween, scientists are releasing a trio of stellar ghosts caught in infrared light by NASA's Spitzer Space Telescope. All three spooky structures, called planetary nebulas, are in fact material ejected from dying stars. As death beckoned, the stars' wispy bits and pieces were blown into outer space. "Some might call the images haunting," said Joseph Hora of the Harvard-Smithsonian Center for Astrophysics, Cambridge, Mass., principal...

Coldest Known Object In Space Reveals Its Ghostly Figure
2013-10-25 06:25:12

April Flowers for redOrbit.com - Your Universe Online The Boomerang Nebula, at a crisp one degree Kelvin (-458 degrees Fahrenheit), is the coldest known object in the Universe. In fact, the Boomerang Nebula is colder than the faint afterglow of the Big Bang, which is the natural background temperature of space. To learn more about this intriguing object, a team of astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) telescope to investigate its frigid properties and...

Life Of Eskimo Nebula Coming To A Beautiful End
2013-07-13 08:19:42

April Flowers for redOrbit.com - Your Universe Online At the end of their lives, stars like our Sun become remarkably photogenic. For example, NGC 2392, located approximately 4,200 light years from Earth, is giving astronomers a beautiful display as it nears the end of its existence. NGC 2392, referred to as a "planetary nebula," has been nicknamed the Eskimo Nebula; however "planetary nebula" is misleading because nebulae have nothing to do with planets. Rather, the term is an...

Hubble Provides Most Detailed Image Of Ring Nebula To Date
2013-05-23 12:48:25

[WATCH VIDEOS: Flying Around The Ring Nebula | Secrets Of The Ring Nebula] Lee Rannals for redOrbit.com — Your Universe Online The Hubble Space Telescope has provided one of the most detailed images of the Ring Nebula so far, allowing scientists to construct a model of the nebula in 3D. The Ring Nebula, or Messier 57, is an archetypal planetary nebula relatively close to Earth at 2,000 light-years away. NASA said Messier 57 is the glowing remains of a Sun-like star. The...

Hubble Image Of Planetary Nebula Resembles Christmas Ribbon
2012-12-18 13:37:12

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...

Dying Star Caught Coming Back To Life
2012-11-15 14:32:42

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...

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...
