Astronomers Offer High Resolution Image Of Cygnus Loop
2012-12-19 11:05:43

April Flowers for redOrbit.com - Your Universe Online The National Optical Astronomy Observatory (NOAO) and WIYN partners have offered this extraordinary wide-field image of the Cygnus loop as an end of the year finale. The image, three degrees to a side, covers an area of the sky about 45 times that of the full moon without sacrificing high resolution. The image is one of the largest astronomical images ever made at over 600 million pixels in size. Located some 1,500 light-years from...

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....

Supernova Remnant Powered By Radioactive Decay Of Titanium
2012-10-18 04:20:39

April Flowers for redOrbit.com - Your Universe Online Radioactive titanium associated with supernova remnant 1987A has been directly detected by ESA's Integral space observatory. The glowing remnant around the exploded star has likely been powered by the decaying from this titanium for the last 20 years. The first space observatory that can simultaneously observe objects in gamma rays, X-rays and visible light, Integral's principal targets are violent explosions known as gamma ray...

New Clues Into Kepler Supernova Explosion Reveal Power, Distance
2012-09-12 13:12:54

April Flowers for redOrbit.com - Your Universe Online A bright new star outshone even Jupiter in 1604 and then it dimmed over several weeks. Johannes Kepler and other sky watchers witnessed this event, and centuries later, the debris left from this stellar explosion is known at the Kepler supernova remnant. Astronomers have studied the Kepler supernova remnant for a long time trying to determine exactly what happened when the star exploded. New analysis of a long observation by NASA's...

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...

Astronomers Spot Fastest Moving Pulsar Ever
2012-06-29 13:31:30

[ Watch the Video ] Lee Rannals for redOrbit.com - Your Universe Online Researchers may have discovered the fastest moving pulsar ever seen using NASA's Chandra X-ray Observatory and ESA's XMM-Newton. Astronomers used X-ray observations, combined with infrared data from the 2MASS project and optical data from the Digitized Sky Survey to find evidence for the record-breaking pulsar. The XMM-Newton image was produced when a massive star exploded as a supernova, leaving behind a...

Chandra Captures Supernova Shock Wave
2012-05-16 03:13:51

Observations with NASA's Chandra X-ray Observatory have provided the first X-ray evidence of a supernova shock wave breaking through a cocoon of gas surrounding the star that exploded. This discovery may help astronomers understand why some supernovas are much more powerful than others. On Nov. 3, 2010, a supernova was discovered in the galaxy UGC 5189A, located about 160 million light years away. Using data from the All Sky Automated Survey telescope in Hawaii taken earlier, astronomers...

A Star Explodes, Turns Inside-Out
2012-04-02 06:01:15

[ Watch the Video ] A new X-ray study of the remains of an exploded star indicates that the supernova that disrupted the massive star may have turned it inside out in the process. Using very long observations of Cassiopeia A (or Cas A), a team of scientists has mapped the distribution of elements in the supernova remnant in unprecedented detail. This information shows where the different layers of the pre-supernova star are located three hundred years after the explosion, and provides...

IMAGE: Remnant Of An Explosion With A Powerful Kick?
2012-02-02 13:47:04

Vital clues about the devastating ends to the lives of massive stars can be found by studying the aftermath of their explosions. In its more than twelve years of science operations, NASA's Chandra X-ray Observatory has studied many of these supernova remnants sprinkled across the Galaxy. The latest example of this important investigation is Chandra's new image of the supernova remnant known as G350.1+0.3. This stellar debris field is located some 14,700 light years from the Earth toward...

Tycho Brahe -- Tycho Brahe (December 14, 1546 - October 24, 1601) was a Danish astronomer. He had Uraniborg built; which become an early "research institute". For purposes of publication, Tycho owned a printing press and paper mill. His best known assistant was Kepler. Tycho realized that progress in the science of astronomy could be achieved, not by occasional haphazard observations, but only by systematic and rigorous observation, night after night, and by using instruments of 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...

Supernova 1987a -- Supernova 1987a was a supernova in the Large Magellanic Cloud, a nearby dwarf galaxy. It occurred approximately 50 kiloparsecs from Earth, the closest supernova since Supernova 1604, which occurred in the Milky Way itself. The light from the supernova reached Earth on February 23, 1987. Its brightness peaked in May with a magnitude of about 3 and slowly declined in the following months. It was modern astronomers' first opportunity to see a supernova up close....

Crab Nebula -- The Crab Nebula (Messier 1, NGC 1952) is the object the which started Charles Messier logging non-cometary objects on his Messier Catalog. It is the expanding cloud of gas thrown off in the explosion that gave rise to the 1054 supernova recorded by Chinese astronomers, now more than 6 light years across (the nebula is currently expanding at 1000 km/sec and the total mass of ejected material is about 0.1 solar masses). The supernova which produced it was bright enough to...
