How Fast Does A Supernova Shockwave Travel? A Japan Team May Have The Answer
2013-08-13 14:51:55

Brett Smith for redOrbit.com - Your Universe Online Some of the most spectacular explosions this side of the Big Bang, supernovae generate unthinkable amounts of force and energy and new research from Keio University in Japan has measured the expansion velocity of a supernova shockwave for the first time. The shockwave measured by the research team was from the supernova remnant W44, which is located approximately 10,000 light years from Earth. Quantifying the expansion and kinetic...

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...

ALMA Scan Reveals Embryonic Star Formation

[ Watch the Video: Zooming in on the Birth of a Monster Star ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers used ESO's Atacama Large Millimeter/submillimeter array (ALMA) to gain one of the best views yet of a star in the process of forming. The embryonic monster star sits inside Spitzer Dark Cloud (SDC) 335.579-0.292 right now, which contains over 500 times the mass of the Sun. Astronomers say the cloud will be giving birth to a very brilliant star with up to...

WATCH VIDEOS: [Panning Across NGC 6559] | [Zooming In On NGC 6559] John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The Danish 1.54-metre telescope located at ESO´s La Silla Observatory in Chile has released a new image of the star-forming region NGC 6559. Located relatively nearby, a mere 5000 light-years from Earth, NGC 6559 is found in the constellation of Sagittarius (The Archer). The nebula is only a few light years across, a stark contrast to its more...

Kepler Supernova Remnant Triggers Identified
2013-03-19 04:33:38

April Flowers for redOrbit.com - Your Universe Online NASA's Chandra X-ray Observatory has identified the cause of Kepler's supernova, the famous explosion first discovered by Johannes Kepler in 1604. The image above shows low (red), intermediate (green) and high (blue) energy X-rays with a star field background from the Digitized Sky Survey. It is already known that the supernova is a Type Ia, which is the thermonuclear explosion of a white dwarf star. Type Ia's are important cosmic...

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 -- 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...
