Odd Magnetar Has A Very Strong Magnetic Field
2013-08-15 04:36:30

redOrbit Staff & Wire Reports - Your Universe Online An odd type of neutron star located approximately 6,500 light years from Earth has one of the strongest magnetic fields in the universe – despite previous suggestions it possessed an unusually low magnetic field. Using the European Space Agency’s (ESA) XMM-Newton space telescope, a team of astronomers studied the object, a magnetar known as SGR 0418+5729 (SGR 0418). This dense and compact object, which is the dead core of a...

AlphaGalileo Foundation Exploring the extreme Universe with a rich new resource Three years' research led by University of Leicester Department of Physics and Astronomy Team produces new catalogue with 531,261 detections of X-ray emitting objects - a new record 372,728 unique X-ray sources identified The total area covered on the sky by the combined observation fields is -1400 square degrees Scientists led by the University of Leicester have set a new record for cosmic X-ray...

NASA X-Ray Observatory Reveals Magnetars More Common Than Thought
2013-05-24 14:42:15

Lee Rannals for redOrbit.com — Your Universe Online NASA's Chandra X-ray Observatory has revealed that some of the most extreme objects in the universe may be more common than previously thought. Magnetars are the dense remains of dead stars that erupt sporadically with bursts of high-energy radiation. When a massive star runs out of fuel its core collapses to form a neutron star. Most neutron stars spin rapidly, but a small fraction have a relatively low spin rate while also...

Astronomers Puzzled By Chameleon-Like Behavior Of Reverse Pulsar
2013-01-25 10:42:24

April Flowers for redOrbit.com - Your Universe Online Pulsars are one of the most baffling classes of astronomical objects. Originally discovered as flickering sources of radio waves, pulsars were soon interpreted as rapidly rotating and strongly magnetized neutron stars about the size of a small city. Because of the oppositely directed beams of radiation emitted from their magnetic poles, pulsars are like cosmic lighthouses. The star spins and the beams sweep past the Earth, displaying a...
