Cosmic Superbubble Shows Its Bright Side
2012-08-31 11:01:49

April Flowers for redOrbit.com - Your Universe Online NASA has released a hauntingly beautiful composite image showing a superbubble in the Large Magellanic Cloud (LMC). The LMC is a small satellite galaxy of the Milky Way located about 160,000 light years from Earth. A superbubble is a cavity, filled with 106 Kelvin gas blown into the interstellar medium by multiple supernovae and stellar winds, hundreds of light years across. These cavities are carved out of the surrounding gas by the...

When Star Clusters Collide: Hubble
2012-08-16 15:08:22

Watch the Video: Simulation of Star Clusters Encounter Lee Rannals for redOrbit.com - Your Universe Online The Hubble Space Telescope has been keeping its eyes fixed on two clusters full of massive stars that may be in the early stages of merging. The star clusters are about 170,000 light-years away in the Large Magellanic Cloud, which is a small satellite galaxy to our Milky Way. What was thought to have been just one cluster in the star-forming region commonly referred to as the...

La Silla Snaps Detailed Image Of The Pipe Nebula
2012-08-15 11:42:39

Videos: Zooming in on the Dark Nebula Barnard 59 | Panning Across the Dark Nebula Barnard 59 Lee Rannals for redOrbit.com - Your Universe Online A new image of the Pipe Nebula has been taken using the Wide Field Imager at the European Space Observatory's La Silla Observatory. The Pipe Nebula is a vast dark cloud of interstellar dust, or a dark nebula, which is a type of nebula that consist of stars, but is so thick with dust that it blocks out the light. The dark nebula is...

XMM-Newton Captures The Beating Heart Of A Newborn Star
2012-07-04 12:42:28

[ Watch the Video ] redOrbit Staff & Wire Reports - Your Universe Online ESA's XMM-Newton has helped to reveal the violent behavior of a young Sun-like star spinning at high speed and spewing out super-hot plasma. Along with information from NASA´s Chandra and Japan´s Suzaku, the findings shed new light on one of the most primary issues in astronomy: the birth of stars like our own Sun. Such stars are born from clouds of gas and dust. These fall apart under gravity...

Flame On! New Image Shows Flame Nebula In Its Full Glory
2012-07-03 12:28:23

Lee Rannals for redOrbit.com - Your Universe Online The cosmos is full of outstanding imagery, and a new image from NASA's Wide-field Infrared Survey Explorer, or WISE, has shot back another outstanding image back to Earth. The latest image, released on Monday, shows a Flame nebula located in the Orion complex, lighting up a cavern of dust. The Nebula is sitting on the eastern hip of Orion the Hunter, which is a constellation that can be seen with the naked eye in the northern...

Blowing Bubbles In The Carina Nebula
2012-06-05 03:24:36

Giant bubbles, towering pillars and cascading clouds of dust and gas fill the star-forming nursery of the Carina Nebula seen here in a stunning new view from Herschel. The Carina Nebula is some 7500 lightyears from Earth and hosts some of the most massive and luminous stars in our Galaxy, including double-star system eta Carinae, which boasts over 100 times the mass of our Sun. The total amount of gas and dust traced by ESA´s Herschel space observatory in this image is equivalent...

APEX Captures Stunning Image Of Dust Near Orion's Belt
2012-05-02 12:52:36

[ Video 1 ] | [ Video 2 ] A new image of the region surrounding the reflection nebula Messier 78, just to the north of Orion´s Belt, shows clouds of cosmic dust threaded through the nebula like a string of pearls. The observations, made with the Atacama Pathfinder Experiment (APEX) telescope[1], use the heat glow of interstellar dust grains to show astronomers where new stars are being formed. Dust may sound boring and uninteresting – the surface grime that hides the beauty...

Hubble Images Searchlight Beams From A Preplanetary Nebula
2012-04-27 09:52:56

The NASA/ESA Hubble Space Telescope has been at the cutting edge of research into what happens to stars like our sun at the ends of their lives. One stage that stars pass through as they run out of nuclear fuel is called the preplanetary or protoplanetary nebula stage. This Hubble image of the Egg Nebula shows one of the best views to date of this brief but dramatic phase in a star´s life. The preplanetary nebula phase is a short period in the cycle of stellar evolution, and has...

Image 1 - La Silla Observatory Eyes A Cluster Within A Cluster
2012-04-25 11:47:24

[ Video 1 ] | [ Video 2 ] The star cluster NGC 6604 is shown in this new image taken by the Wide Field Imager attached to the MPG/ESO 2.2-meter telescope at the La Silla Observatory in Chile. It is often overlooked in favor of its more prominent neighbor, the Eagle Nebula (also known as Messier 16), that lies a mere wingspan away. But the framing of this picture, which places the star cluster in a landscape of surrounding gas and dust clouds, shows what a beautiful object NGC 6604 is in...

Complex organic compounds, including many important to life on Earth, were readily produced under conditions that likely prevailed in the primordial solar system. Scientists at the University of Chicago and NASA Ames Research Center came to this conclusion after linking computer simulations to laboratory experiments. Fred Ciesla, assistant professor in geophysical sciences at UChicago, simulated the dynamics of the solar nebula, the cloud of gas and dust from which the sun and the planets...

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...
