The Nuclear Spectroscopic Telescope Array, or NuSTAR, recently spotted the brightest pulsar ever recorded using X-ray optics designed by a team that included researchers from the Lawrence Livermore National Laboratory. Livermore, California (PRWEB) October 10, 2014 A supernova is the cataclysmic death of a star, but it seems its remnants shine on. Astronomers have found a pulsating, dead star beaming with the energy of about 10 million suns. This is the brightest pulsar -- a dense stellar...

WASHINGTON, Oct. 8, 2014 /PRNewswire-USNewswire/ -- Astronomers have found a pulsating, dead star beaming with the energy of about 10 million suns. This is the brightest pulsar - a dense stellar remnant left over from a supernova explosion - ever recorded. The discovery was made with NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR. http://photos.prnewswire.com/prnvar/20081007/38461LOGO "You might think of this pulsar as the 'Mighty Mouse' of stellar remnants," said Fiona...

WASHINGTON, Aug. 18, 2014 /PRNewswire-USNewswire/ -- Astronomers have uncovered rhythmic pulsations from a rare type of black hole 12 million light-years away by sifting through archival data from NASA's Rossi X-ray Timing Explorer (RXTE) satellite. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The signals have helped astronomers identify an unusual midsize black hole called M82 X-1, which is the brightest X-ray source in a galaxy known as Messier 82. Most black holes...

University of Maryland and NASA astronomers used rhythmic flares of light to measure a brilliant object 12 million light years from Earth, confirming that it is a rare, mysterious intermediate-mass black hole. (PRWEB) August 17, 2014 The universe has so many black holes that it’s impossible to count them all. There may be 100 million of these intriguing astral objects in our galaxy alone. Nearly all black holes fall into one of two classes: big, and colossal. Astronomers know that black...

Galactic Superwinds Power Up Gas Clouds In M82

redOrbit Staff & Wire Reports - Your Universe Online Shockwaves originating from the central starburst region of galaxy Messier 82 (M82) are most likely the source of bright clouds within a “cap” of gas clouds located some 40,000 light years away, astronomers have discovered. Kyoto University´s Dr. Kazuya Matsubayshi and an international team of colleagues observed the nearby starburst galaxy, which is located approximately 12 million light-years away in the...

NASA's Wide-field Infrared Survey Explorer has captured a new view of two companion galaxies -- a somewhat tranquil spiral beauty and its rambunctious partner blazing with smoky star formation. The unlikely pair, named Messier 81 and Messier 82, got to know each other a lot better during an encounter that occurred a few hundred million years ago. As they swept by each other, gravitational interactions triggered new bursts of star formation. In the case of Messier 82, also known as the Cigar...

A new Chandra X-ray Observatory image of Messier 82, or M82, shows the result of star formation on overdrive. M82 is located about 12 million light years from Earth and is the nearest place to us where the conditions are similar to those when the Universe was much younger with lots of stars forming. M82 is a so-called starburst galaxy, where stars are forming at rates that are tens or even hundreds of times higher than in a normal galaxy. The burst of star birth may be caused by a close...

New evidence from NASA's Chandra X-ray Observatory and ESA's XMM-Newton strengthens the case that two mid-sized black holes exist close to the center of a nearby starburst galaxy. These "survivor" black holes avoided falling into the center of the galaxy and could be examples of the seeds required for the growth of supermassive black holes in galaxies, including the one in the Milky Way. For several decades, scientists have had strong evidence for two distinct classes of black hole: the...

Nearby galaxies undergoing a furious pace of star formation also emit lots of gamma rays, say astronomers using NASA's Fermi Gamma-ray Space Telescope. Two so-called "starburst" galaxies, plus a satellite of our own Milky Way galaxy, represent a new category of gamma-ray-emitting objects detected both by Fermi and ground-based observatories. "Starburst galaxies have not been accessible in gamma rays before," said Fermi team member Seth Digel, a physicist at SLAC National Accelerator...

Nearly 100 years ago, scientists detected the first signs of cosmic rays - subatomic particles (mostly protons) that zip through space at nearly the speed of light. The most energetic cosmic rays hit with the punch of a 98-mph fastball, even though they are smaller than an atom. Astronomers questioned what natural force could accelerate particles to such a speed. New evidence from the VERITAS telescope array shows that cosmic rays likely are powered by exploding stars and stellar "winds."...

The M81 Group, containing the well known galaxies Messier 81 and Messier 82, is a group of galaxies within the constellation Ursa Major. Along with Messier 81 and 82 are several other galaxies with apparent brightness. The center, located at an approximate distance of 3.6 Mpc, is one of the nearest groups to the Local Group. The total estimated mass of the group is (1.03 ± 0.17) × 1012M☉. The Virgo Supercluster contains the M81 Group, the Local Group, and some other nearby...
