Signal From The Unseen Universe - Leicester Scientists Uncover Dark Matter Particle Signature

April Flowers for redOrbit.com - Your Universe Online For decades, space scientists have been trying to prove, or disprove, the existence of axions — which were first postulated in 1977 by the Peccei–Quinn theory. A new study from the...

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...

Pulsating X-rays Allow XMM-Newton To Reveal A Mysterious Star
2014-06-04 03:32:58

ESA XMM-Newton has revealed a unique star. It is a celestial chimera with the body of a normal massive star yet the magnetic field of a dead, stellar dwarf. This makes it a singular object among the billions of known stars. The race is now on to understand why it behaves in this way because the work hints at an unanticipated link between the deep interior of a star and the surrounding atmosphere. The star is known only by its catalogue designation, Xi1 Canis Majoris. It lies some...

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...

Pair Of Supermassive Black Holes Discovered By XMM-Newton
2014-04-22 14:09:30

ESA A pair of supermassive black holes in orbit around one another have been spotted by XMM-Newton. This is the first time such a pair have been seen in an ordinary galaxy. They were discovered because they ripped apart a star when the space observatory happened to be looking in their direction. Most massive galaxies in the Universe are thought to harbor at least one supermassive black hole at their center. Two supermassive black holes are the smoking gun that the galaxy has merged with...

NuSTAR Helps Scientists Hunt For Medium-Sized Black Holes
2013-11-27 15:39:33

Lee Rannals for redOrbit.com - Your Universe Online NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR) is helping scientists determine whether black holes need a medium-sized category. Black holes are known to either come in masses of only about 10 times that of our sun, or the equivalent in mass of up to 10 billion suns. However, NuSTAR could be finally finding a middle ground. "Exactly how intermediate-sized black holes would form remains an open issue," Dominic Walton, of the...

coma cluster of galaxies
2013-09-20 04:46:30

April Flowers for redOrbit.com - Your Universe Online In the Coma cluster of galaxies, a team of astronomers has discovered enormous arms of hot gas using NASA's Chandra X-ray Observatory and ESA's XMM-Newton. These arms span at least a half a million light years. The scientists say they will provide insight into how the Coma cluster has grown through mergers of smaller groups and clusters of galaxies to become one of the largest structures in the Universe held together by gravity. A...

Black Holes Shine For NuSTAR
2013-09-06 06:38:46

[ Listen to the Podcast: Supermassive Black Holes – With Guest Dr. Kelly Holley-Bockelmann ] April Flowers for redOrbit.com - Your Universe Online The Nuclear Spectroscopic Telescope Array (NuSTAR) spacecraft, NASA’s black-hole-hunter, had identified its first 10 supermassive black holes. Over the next two years, the NuSTAR team expects to find hundreds of black holes. Supermassive black holes – which are black holes surrounded by thick disks of gas – are gargantuan...

NASA NuSTAR Telescope Showcases Unique X-Ray Images Of Space
2013-08-30 07:47:15

April Flowers for redOrbit.com - Your Universe Online For the first time, NASA’s Nuclear Spetroscopic Telescope Array (NuSTAR) is giving the wider astronomical community a look at its unique X-ray images of the cosmos. NASA’s High Energy Astrophysics Science Archive Research Center (HEASARC) made the first batch of data from the black-hole hunting telescope publicly available on August 29. "We are pleased to present the world with NuSTAR's first look at the sky in high-energy X-rays...

XMM-Newton's Dance Of The X-rays
2013-07-29 08:36:40

ESA Like car tail lights streaking through a busy city at night, this unique image records over a thousand movements made by ESA's XMM-Newton space telescope as it shifts its gaze from one X-ray object to another. Orbiting in space since 1999, XMM-Newton is studying high-energy phenomena in the Universe, such as black holes, neutron stars, pulsars and stellar winds. Even when moving from object to object, the space telescope collects data. These slews are represented by the bright...
