Whitney Clavin, Jet Propulsion Laboratory Our Milky Way galaxy is littered with the still-sizzling remains of exploded stars. When the most massive stars explode as supernovas, they don't fade into the night, but sometimes glow ferociously with high-energy gamma rays. What powers these energetic stellar remains? NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, is helping to untangle the mystery. The observatory's high-energy X-ray eyes were able to peer into a particular site...

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...

Intermediate Mass Black Hole in M82

redOrbit Staff & Wire Reports - Your Universe Online Astronomers from the University of Maryland and NASA’s Goddard Space Flight Center in Greenbelt, Maryland have accurately measured and confirmed the existence of a black hole roughly 400 times the mass of our sun. Black holes that range in size from about 10 to 100 times the mass of our sun are the remnants of dying stars, while much larger supermassive black holes are more than one million times our sun’s mass and typically...

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...

supernova SN 2014J
2014-08-14 10:48:55

NASA/Harvard-Smithsonian Center for Astrophysics New data from NASA’s Chandra X-ray Observatory offer a glimpse into the environment of a star before it exploded earlier this year, and insight into what triggered one of the closest supernovas witnessed in decades. The data gathered on the Jan. 21 explosion, a Type Ia supernova, allowed scientists to rule out one possible cause. These supernovas may be triggered when a white dwarf takes on too much mass from its companion star,...

supermassive black hole

April Flowers for redOrbit.com - Your Universe Online An extreme and rare event in the region of space immediately surrounding a supermassive black hole has been captured by NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR. The corona of the black hole, a compact source of X-rays that is situated nearby, has moved closer to the black hole over a period of just days. "The corona recently collapsed in toward the black hole, with the result that the black hole's intense gravity...

Learn About The "X-Factor" Of NASA's Webb Telescope

[ Watch The Video: The X Factor: Behind The Webb ] Rob Gutro, NASA NASA's James Webb Space Telescope and Chandra X-ray observatory have something in common: a huge test chamber used to simulate the hazards of space and the distant glow of starlight. Viewers can learn about this mysterious chamber and its history in "X-Factor," a new video in the "Behind the Webb" series. The video takes viewers behind the scenes to understand more about the Webb telescope and how it compares with...

European Space Agency Selects Athena Advanced Telescope For Study Of High-Energy Astrophysics
2014-06-27 09:41:59

Gerard LeBlond for redOrbit.com - Your Universe Online The European Space Agency (ESA) is in the process of launching a second “Large-class” mission to explore the universe for high-energy astrophysics and selected the Athena advanced telescope for the task. The mission is scheduled for launch in 2028 to study the hot and energetic Universe as part of ESA’s Cosmic Vision 2015 to 2025 plan. Athena is a large X-ray telescope combined with state-of-the-art scientific instruments...

Stream Of Gas Observed Escaping Grasp Of Supermassive Black Hole
2014-06-20 10:53:54

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The classic image of black hole systems is the in-flowing gas being consumed by the singularity. However, black holes are far from simply being cosmic vacuum cleaners, and occasionally even exhibit some strange behavior. Recently, a team of astronomers found a clumpy stream of gas quickly flowing outward from the supermassive black hole at the core of the galaxy NGC 5548. This unusual phenomenon was discovered when a...

ESA’s New X-ray Optics To Observe The Hot Universe
2014-05-16 03:41:51

ESA A new idea to use super-polished silicon wafers as the heart of a telescope is set to reveal more of the hot, high-energy Universe, peering back into its turbulent history. Invisible X-rays tell us about the very hot matter in the Universe – black holes, supernovas and superheated gas clouds. Today’s X-ray observatories, ESA’s XMM-Newton and NASA’s Chandra, were launched in the last century, and are still delivering world-class science. But they are starting to age. To...
