Astronomers Detect Relatively Cool Supernova Remnant
2013-07-05 14:00:28

Lee Rannals for redOrbit.com - Your Universe Online An international team of astronomers detected surprisingly low temperatures in the remnant of the supernova 1987A, helping to explain the mystery of why space is filled with dust grains and molecules. The team used the Herschel Space Observatory and Atacama Millimeter and Submillimeter Array (ALMA) to study the supernova remnant. They were able to find a vast reservoir of unexpectedly cold molecules and dust. "The powerful explosion...

Lee Rannals for redOrbit.com – Your Universe Online Astronomers will be reporting details about a supernova remnant known as G1.9+0.3 in the upcoming issue of The Astrophysical Journal Letters. In 2008, a team of scientists discovered the remains of a supernova known to have occurred in the Milky Way, about 28,000 light years away from Earth. The explosion would have been visible from Earth a little more than a hundred years ago, assuming it was not obscured by dust and gas....

Supernova Light Echo Detected
2013-06-05 13:28:46

Lee Rannals for redOrbit.com - Your Universe Online Astronomers discovered light echoing off of material surrounding a recent supernova explosion, supporting the theory that exploding white dwarfs become unstable from matter donated by large non-degenerate stars. The team detected the light echo coming off of SN 2009ig, making it the sixth and most luminous discovered from a type Ia supernova. A light echo works similarly in principle to the more familiar sound echoes heard on Earth....

First High-Resolution Radio Images Of Supernova 1987A Released
2013-04-02 06:25:15

Lawrence LeBlond for redOrbit.com - Your Universe Online An observation of the Large Magellanic Cloud (LMC) in February of 1987 left astronomers thinking they had discovered the beginnings of a new star. However, what they had witnessed was the end of one of the brightest supernovae seen from Earth since the invention of the telescope some 400 years earlier. And in the two-plus decades since the discovery of the remnant Supernova 1987A, researchers have continued their gaze on one of 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...

Astronomers Discover Youngest Black Hole In Milky Way
2013-02-13 12:11:40

Lee Rannals for redOrbit.com — Your Universe Online A rare explosion from a rotating star may have created the most recent black hole formed in the Milky Way galaxy. Astronomers using NASA's Chandra X-ray Observatory claim that matter was ejected at high speeds along the poles of a rotating star, creating a supernova remnant, W49B, which may contain a young black hole. "W49B is the first of its kind to be discovered in the galaxy," said Laura Lopez, who led the study at the...

Manatee Nebula Named For Its Resemblance To The Sea Cow
2013-01-19 07:04:37

[ Watch the Video: A Microquasar Makes a Giant Manatee Nebula ] redOrbit Staff & Wire Reports - Your Universe Online Thanks to a powerful National Science Foundation (NSF) telescope and an observation made by one National Radio Astronomy Observatory (NRAO) official, the W50 nebula located approximately 18,000 light years away has a new name — the Manatee Nebula. Images of the massive supernova remnant captured recently by the NSF´s Karl G. Jansky Very Large Array (VLA)...

Supernova Explosions Simulated With Complex Computer Code
2013-01-09 08:00:01

April Flowers for redOrbit.com - Your Universe Online Wanting to bridge the gap between what is known about exploring stars and the remnants left behind thousands of years later, two University of Texas at Arlington students and their colleagues are trying something new — using SNSPH, a complex computer code developed at Los Alamos National Laboratory. The two students, Carola I. Ellinger, a post-doctoral researcher at UT Arlington, and Sangwook Park, an assistant professor in the...

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....

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...

  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
