[ Watch The Video: Zooming In On To The Toby Jug Nebula ] Lee Rannals for redOrbit.com - Your Universe Online ESO astronomers using the European Souther Observatory's (ESO) Very Large Telescope (VLT) reported today that they have captured a detailed image of the Toby Jug Nebula. The nebula featured in the latest ESO image is a cloud of gas and dust surrounding a red giant star. The image shows the characteristic arc structure of the nebula resembles a jug with a handle. The Toby Jug...

Sharpest Ever Image Of Prawn Nebula Unveiled
2013-09-18 10:42:57

[ Watch the Video: Zooming In On The Prawn Nebula ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers using the Very Large Telescope (VLT) at the European Southern Observatory's (ESO) Paranal Observatory in Chile have taken the sharpest image ever of the Prawn Nebula. The stellar nursery, formally known as IC 4628, sits 6,000 light-years from Earth in the constellation of Scorpius. The new image shows clumps of hot new-born stars nestled among the clouds making up the...

Magnetic Jets Stars Final Transformation

John P. Millis, PhD for redOrbit.com - Your Universe Online In general, main sequence stars die in one of two ways: high mass stars, those several times larger than our Sun, will explode in brilliant supernovae, leaving behind a shock remnant with a dense neutron star or black hole at its center. Lower mass stars like our Sun will transition into a planetary nebula. The outer envelope of the star is expressed into the interstellar medium, and the star’s gravity relinquishes its grip....

Bizarre Alignment Observed In Butterfly-Shaped Nebulae
2013-09-04 08:57:07

Lee Rannals for redOrbit.com - Your Universe Online A new study by astronomers from the University of Manchester shows how planetary nebulae line up in the sky in the same way. A planetary nebula occurs in the final stages of a star's life when its outer layers begin to stretch out into the surrounding space. Such nebulae can create beautiful objects in the night sky, with some stretching out into an hourglass or butterfly shape. The latest research, published in the Monthly Notices of...

Not All Rogue Planets Are Born Within Solar Systems
2013-08-20 11:30:55

Lee Rannals for redOrbit.com - Your Universe Online A team of astronomers say free-floating planets can be born freely, outside of an existing solar system. Previously, scientists believed free-floating planets, or "rogue planets," must have been ejected from existing planetary systems. However, telescopes at Chalmers University of Technology have helped astronomers discover not all of these rogue planets were created this way, but that some were born free. Scientists believe there...

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...

Cats Paw Nebula Baby Boom
2013-06-06 13:58:02

Lee Rannals for redOrbit.com - Your Universe Online Astronomers presented research on Wednesday at the American Astronomical Society (AAS) about how the Cat's Paw Nebula is experiencing a "baby boom." The team said the nebula, or NGC 6334, is forming stars at a more rapid pace than the Orion Nebula, which is one of the closest stellar nurseries to Earth. "It might resemble a 'mini-starburst,' similar to a scaled-down version of the spectacular bursts sometimes seen in other...

NGC 6334: Shedding Light On Starburst Regions
2013-06-05 13:00:40

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Stars are formed in massive clouds of gas that are being compressed by some nearby event. Over time, the region will be consumed by the forming stars, leaving a cluster that will eventually drift apart. But what starts this process in the first place? Often these regions of star formations -- known as starburst regions -- are found in distant galaxies where the activity level is very high. But this presents a problem:...

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...

Supernova Remnant -- A supernova remnant (SNR) is made up of the materials left behind by the gigantic explosion of a star in a supernova. There are two possible routes to this end: either a massive star may cease to generate fusion energy in its core, and collapse inward under the force of its own gravity, or a white dwarf star may accumulate material from a companion star until it reaches a critical mass and undergoes a similar collapse. In either case, the resulting supernova...

Star -- A star is a self-gravitating sphere of plasma in hydrostatic equilibrium that generates energy in its interior through the process of nuclear fusion. Energy from this process radiates into space as electromagnetic radiation and neutrinos. Star formation and evolution As learned by star formation astronomers, stars are born in molecular clouds, regions of higher density of matter, and form by gravitational instability inside those clouds. High mass stars illuminate powerfully...

Reflection Nebula -- In astronomy, reflection nebulae are clouds of dust which are simply reflecting the light of a nearby star or stars. The nearby star or stars are not hot enough to cause ionization in the gas of the nebula like in emission nebulae but are bright enough to give sufficient scattering to make the dust visible. The distiction between these two types of nebulae was done by Hubble in 1922. They are usually blue because the scattering is more efficient for blue light...

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...
