NASA's Fermi Gamma-ray Space Telescope Sees A 'Transformer' Pulsar

[ Watch The Video: Fermi Catches A ‘Transformer’ Pulsar ] NASA In late June 2013, an exceptional binary containing a rapidly spinning neutron star underwent a dramatic change in behavior never before observed. The pulsar's radio...

[ Watch the Video: Radio Wave Emission From A Pulsar ] John P. Millis, Ph.D. for redOrbit.com - Your Universe Online When a massive star, typically around 10 times the mass of our Sun, reaches the end of its main-sequence life, a series of events begins that eventually leads to a brilliant supernova. The shockwave from the event ejects most of the material into the surrounding interstellar medium, leaving a brilliant blanket of glowing gas that hangs in the sky for thousands of years....

[ Watch The Video: A Black Widow Pulsar Consumes its Mate ] Francis Reddy, NASA Black widow spiders and their Australian cousins, known as redbacks, are notorious for their tainted love, expressed as an unsettling tendency to kill and devour their male partners. Astronomers have noted similar behavior among two rare breeds of binary system that contain rapidly spinning neutron stars, also known as pulsars. "The essential features of black widow and redback binaries are that...

New Pulsars Discovered In Archival Data

AlphaGalileo Foundation Einstein@Home discovers 24 new pulsars in archival data. The combined computing power of 200,000 private PCs helps astronomers take an inventory of the Milky Way. The Einstein@Home project connects home and office PCs of volunteers from around the world to a global supercomputer. Using this computer cloud, an international team lead by scientists from the Max Planck Institutes for Gravitational Physics and for Radio Astronomy analyzed archival data from the CSIRO...

Evidence Of New Phase In Neutron Stars Discovered
2013-06-14 13:48:03

Lee Rannals for redOrbit.com — Your Universe Online University of Alicante researchers have discovered the first evidence of a new phase in neutron stars. The scientists wrote in the journal Nature Physics that they have detected what may be the first observational evidence of existence of a new exotic phase of matter in what is known as the "inner crust" of neutron stars, or pulsars. "This may be the first observational evidence of existence of the phase of nuclear...

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...

XMM-Newton has detected periodic X-ray emission, or the pulsed heartbeat of a weird new type of star. Collecting the X-rays from the so-called rotating radio transient has confirmed the nature of the underlying celestial object and given astronomers a new insight into these exotic objects. The observations were made using XMM-Newton's European Photon Imaging Camera (EPIC), which targeted the celestial object RRAT J1819"“1458. Astronomers observed the object for around 12 hours and...

Jodrell Bank -- Astronomers of the University of Manchester's Jodrell Bank Observatory (UK) have led an international team which used the Parkes radio telescope in Australia to find a new kind of cosmic object which sends out radio flashes. These flashes are very short and very rare: one hundredth of a second long, the total time the objects are visible amounts to only about one tenth of a second per day. The discovery will be published in this week's issue of the journal Nature. Eleven...
