Young Supernova Remnant Discovered By NASA’s Swift Satellite
2013-03-16 10:18:20

redOrbit Staff & Wire Reports — Your Universe Online NASA´s Swift space observatory detected the previously undiscovered remains of a supernova during an extensive X-ray survey of the Milky Way, officials from the US space agency announced on Friday. NASA believes the shattered star remains, which have been named G306.3—0.9 after the coordinates of its sky position, are among the youngest-known supernova remnants in the galaxy. “Astronomers have previously...

Astronomers Spot 'Soccer Ball' Molecules In Space
2013-03-05 13:10:23

Lee Rannals for redOrbit.com - Your Universe Online An international team of astronomers are reporting in The Astrophysical Journal they have spotted what resembles a soccer ball sitting in the dying star M1-11. Five instruments helped astronomers detect C60 fluorine in the dying star, which are molecules of carbon with 60 atoms arranged in patterns that resemble a soccer ball. Astronomers used the Subaru Telescope, the Spitzer Space Telescope (SST), ESO's Very Large Telescope, the...

Supernova Gives Scientists Clues Into Origins Of Cosmic Rays
2013-02-14 13:19:29

[ Watch the Video: Fermi Proves Supernova Remnants Produce Cosmic Rays ] Lee Rannals for redOrbit.com - Your Universe Online A thousand-year-old supernova has given the European Space Observatory's Very Large Telescope (VLT) ample opportunity to gain some clues about the origins of cosmic rays. The new observations, reported in the journal Science today, suggest the presence of fast-moving particles in the supernova remnant. Over a thousand years ago, in 1006 AD, a new star was...

New Image Shows Off Star Birth Region In Orion
2013-01-23 05:14:35

Lee Rannals for redOrbit.com - Your Universe Online A new image released by the European Space Observatory (ESO) shows off a great view of clouds of cosmic dust in Orion. ESO's Atacama Pathfinder Experiment (APEX) telescope in Chile helps bring out the heat glow of the dust, revealing places where new stars are being formed. Dense clouds of cosmic gas and dust in space are the birthplaces of new stars. When viewing these in visible light, the dust is dark and obscuring, which helps...

Astronomers Capture Rare Glimpse Of Star-Forming Region In Visible Light
2013-01-16 07:00:46

[Watch Videos: 1 - Zooming in on Lupus 3 / 2 - Panning Over Lupus 3] Lawrence LeBlond for redOrbit.com - Your Universe Online The European Southern Observatory (ESO) released a stunning new image of a dark cloud where new stars are forming, along with a cluster of brilliant stars that have already emerged from the stellar nursery. The new image, taken with MPG/ESO 2.2-meter telescope at La Silla Observatory in Chile, is one of the finest and clearest ever taken in visible light of...

Supernova Remnant Reveals Its Aftershock
2012-11-14 12:57:25

Lee Rannals for redOrbit.com - Your Universe Online A new image released by the European Space Agency (ESA) shows the aftershock of a stellar explosion coming from supernova remnant W44. W44 is about 10,000 light-years away from Earth in a forest of dense star-forming clouds in the constellation of Aquila. ESA said the image is one of the best examples of a supernova remnant interacting with its parent molecular cloud. The supernova remnant measures about 100 light-years across....

Seagull Nebula
2012-09-26 13:55:54

Watch the Video: [ Zooming in on the Seagull Nebula ] Watch the Video: [ Panning Across the Head of the Seagull Nebula ] Lee Rannals for redOrbit.com - Your Universe Online A new image taken by the European Space Observatory's La Silla Observatory shows off a stellar nursery nicknamed the Seagull Nebula. This nebula looks like the head of the seagull, and glows brightly due to the energetic radiation from a hot young star that sits at its heart. Nebulae are interstellar...

Galactic Center And The Pigtail Molecular Cloud
2012-09-05 11:06:34

Lee Rannals for redOrbit.com - Your Universe Online Astronomers using a telescope at the National Astronomical Observatory of Japan have discovered a molecular cloud that has a peculiar helical structure. The team, led by Shinji Matsumura, a second year Ph. D. candidate, named it a "pigtail" molecular cloud due to its morphology. The pigtail molecular cloud is located in the galactic center, about 30,000 light years away from the solar system. Giant molecular clouds found in this...

Chandra Finds Young Supernova Remnant Spitting Out X-rays
2012-07-31 05:18:12

April Flowers for redOrbit.com - Your Universe Online In a galaxy not that far away, astronomically speaking at least, researchers using NASA's Chandra X-ray Observatory have detected the first x-rays emitted by the debris of a young supernova, SN 1957D. 15 million light years from Earth, in the M83 spiral galaxy, SN 1957D is one of only a few supernova located outside the Milky Way galaxy that is detectable in both radio and optical wavelengths, decades after the explosion itself was...

New Hubble Image Shows Space Geyser
2012-07-03 14:32:32

Lee Rannals for redOrbit.com - Your Universe Online The Hubble Space Telescope has unleashed a new image of a geyser of hot gas flowing from a newborn star. In the new image, Herbig-Haro 110 is seen showing off a turbulent streamer of gas, streaking across the picture. "Resembling a Fourth of July skyrocket, Herbig-Haro 110 is a geyser of hot gas from a newborn star that splashes up against and ricochets from the dense core of a cloud of molecular hydrogen," NASA said....

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 Formation -- Star formation is the process by which gas in molecular clouds gets transformed into stars. In the current paradigm of star formation, cores of molecular clouds (regions of specially high density) became gravitationally unstable, and start to concentrate. Part of the gravitational energy lost in the process is radiated in the infrared, another part increases the temperature of the core. The accretion of material happen partially though a circumstellar disc. When...

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...
