WASHINGTON, July 22, 2014 /PRNewswire-USNewswire/ -- Fifteen years ago, NASA's Chandra X-ray Observatory was launched into space aboard the Space Shuttle Columbia. Since its deployment on July 23, 1999, Chandra has helped revolutionize our understanding of the universe through its unrivaled X-ray vision. http://photos.prnewswire.com/prnvar/20081007/38461LOGO Chandra, one of NASA's current "Great Observatories," along with the Hubble Space Telescope and Spitzer Space Telescope, is...

Dissecting Dust from Detonation of Dead Star

Brett Smith for redOrbit.com - Your Universe Online A supernova occurs when a tiny white dwarf star detonates in a massive blast and a common class of these explosions, called Type Ia, occurs when two white dwarfs orbiting each other collide. Based on observations taken from the Spitzer Space Telescope, NASA scientists have uncovered evidence of a much rarer Type Ia supernova scenario – when a white dwarf feeds off an aging giant, to the point of explosion. According to a report...

[ Watch the Video: Sloshing Star Goes Supernova ] April Flowers for redOrbit.com - Your Universe Online For the first time, astronomers have peered into the heart of an exploding star during the final minutes of its life. This groundbreaking achievement is one of the primary goals of NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) mission, which launched in June 2012. NuSTAR is tasked to measure high energy X-ray emissions from exploding stars, also known as supernovae, and...

WASHINGTON, Feb. 19, 2014 /PRNewswire-USNewswire/ -- One of the biggest mysteries in astronomy, how stars blow up in supernova explosions, finally is being unraveled with the help of NASA's Nuclear Spectroscopic Telescope Array (NuSTAR). (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The high-energy X-ray observatory has created the first map of radioactive material in a supernova remnant. The results, from a remnant named Cassiopeia A (Cas A), reveal how shock waves...

Chandra X-ray Observatory Sees Runaway Pulsar Firing A Record-breaking Jet
2014-02-19 09:27:55

NASA NASA's Chandra X-ray Observatory has seen a fast-moving pulsar escaping from a supernova remnant while spewing out a record-breaking jet – the longest of any object in the Milky Way galaxy -- of high-energy particles. The pulsar, a type of neutron star, is known as IGR J11014-6103. IGR J11014-6103's peculiar behavior can likely be traced back to its birth in the collapse and subsequent explosion of a massive star. Originally discovered with the European Space Agency satellite...

[ Watch the Video: What Interstellar Blast Is Lighting Up The Sky? ] redOrbit Staff & Wire Reports - Your Universe Online Several NASA spacecraft and Earth-based observatories, including the Hubble Space Telescope and the Chandra X-ray Observatory, are studying an incredibly close supernova that took place on January 21, officials from the US space agency announced on Friday. The stellar explosion, which has been designated SN 2014J, lies approximately 12 million light-years away...

[ Watch the Video: Supernovas May Be Galactic Dust Factories ] Lee Rannals for redOrbit.com - Your Universe Online A new image of a recent supernova could offer up insight to scientists about how galaxies became so dusty. Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope have observed the remains of supernova 1987A located in the Large Magellanic Cloud about 168,000 light-years from Earth. This is the closest observed supernova explosion since Johannes...

As part of their study, Mike Barlow of the University College London Department of Physics and Astronomy and his colleagues used the...

Tycho Supernova Mach 1000 Shock Wave

John P. Millis, PhD for redOrbit.com - Your Universe Online Somewhere in the Universe a star or stellar remnant is preparing to explode. Binary white dwarf systems can build up in mass as the compact object accretes mass from its companion. Eventually, the tiny ball of matter will explode in a brilliant event known as a supernova. The blast can glow for weeks or even months before eventually fading. However, the shock wave from the event will travel through the surrounding medium,...

Astronomers Say Supernova Will Be Visible From Earth Within 50 Years

[ Watch the Video: Is There A Supernova In Your Future? ] Brett Smith for redOrbit.com - Your Universe Online A supernova is one of the most brilliant events to take place in the universe and astronomers at The Ohio State University have determined we will see one in the Milky Way Galaxy within the next 50 years. While the odds of actually seeing a star explode with the naked eye is very low during that time span, a supernova would be visible to specialized telescopes in the form of...

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...
