NuSTAR Observatory Busy High Energy Events
2013-06-18 11:08:53

Brett Smith for redOrbit.com - Your Universe Online NASA´s NuSTAR orbiting observatory is designed to investigate high-energy events throughout the universe, and the cosmos has been keeping it busy in recent months, producing one event after another. In early April, the galaxy Markarian 421 produced a high-energy event that increased its brightness by more than 50 times its usual level. Markarian 421 is known as a blazer, a unique class of galaxies with supermassive "feeding" black...

NuSTAR Observes Dormant Black Hole In Nearby Sculptor Galaxy
2013-06-12 08:35:23

April Flowers for redOrbit.com - Your Universe Online NASA´s Chandra X-ray Observatory caught signs of what appeared to be a black hole eating gas at the middle of the nearby Sculptor Galaxy nearly a decade ago. A new observation by NASA´s Nuclear Spectroscopic Telescope Array (NuSTAR) has found the black hole asleep. Details of NuSTAR´s findings were published in the Astrophysical Journal. "Our results imply that the black hole went dormant in the past 10 years," said...

NASA X-Ray Observatories Reveal Black Hole Spin
2013-02-27 17:22:50

John P. Millis, PhD for redOrbit.com — Your Universe Online One of the challenges of studying black holes — incredibly dense stellar remnants arising from massive supernova explosions — is that it is extremely difficult to measure the spin of such objects. And it is this motion that is of particular interest, since Einstein´s theory of General Relativity predicts that the gravitational waves produced from their rotation can distort the very fabric of space-time...

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...

NASA NuSTAR Catches Glimpse Of Supernova Remnant, Black Holes
2013-01-08 12:04:09

redOrbit Staff & Wire Reports - Your Universe Online NASA has released a pair of new images captured by the Nuclear Spectroscopic Telescope Array (NuSTAR) — one depicting a pair of black holes lurking inside a spiral galaxy, and the other featuring a look at the supernova remnant Cassiopeia A. The two pictures, which were revealed Monday at the American Astronomical Society (AAS) meeting in Long Beach, California, “showcase why NuSTAR is giving us an unprecedented look...
