Fermi Large Area Telescope reveals pulsing gamma-ray sources Scientists at the Naval Research Laboratory (NRL) Space Science Division and a team of international researchers have positively identified cosmic sources of gamma-ray emissions through the discovery of 16 pulsating neutron stars. view more (2009-09-10)
NASA's Fermi Telescope Probes Dozens of Pulsars With NASA's Fermi Gamma-ray Space Telescope, astronomers now are getting their best look at those whirling stellar cinders known as pulsars. view more (2009-07-07)
Jekyll-Hyde neutron star discovered by researchers Like something out of a Robert Louis Stevenson novel, researchers at NASA and McGill University discovered an otherwise normal pulsar which violently transformed itself temporarily into a magnetar, a stellar metamorphosis never observed before. view more (2008-02-22)
Old pulsars still have new tricks to teach us The super-sensitivity of ESA's XMM-Newton X-ray observatory has shown that the prevailing theory of how stellar corpses, known as pulsars, generate their X-rays needs revising. view more (2006-07-26)
Part-time pulsar yields new insight into inner workings of cosmic clocks Astronomers using the 76-m Lovell radio telescope at the University of Manchester's Jodrell Bank Observatory have discovered a very strange pulsar that helps explain how pulsars act as 'cosmic clocks' and confirms theories put forward 37 years ago to explain the way in which pulsars emit their regular beams of radio waves-considered to be one of... view more...

The cosmos is green: Researchers catch nature in the act of 'recycling' a star For the first time, researchers have observed a singular cosmic act of rebirth: the transformation of an ordinary, slow-rotating pulsar into a superfast millisecond pulsar with an almost infinitely extended lifespan. view more (2009-05-22)
General relativity survives gruelling pulsar test Astronomers have used a pair of pulsars orbiting each other, found with CSIRO's Parkes telescope in 2003, to show that Einstein's theory of general relativity is correct to within 0.05% - the most stringent limit to date. view more (2006-09-18)
Powerful explosions suggest neutron star missing link Observations from NASA's Rossi X-ray Timing Explorer (RXTE) have revealed that the youngest known pulsing neutron star has thrown a temper tantrum. view more (2008-02-22)
Astronomers catch a star being revved-up Researchers have witnessed a star being transformed into an object that spins at almost 600 times a second using telescopes in the USA and the Netherlands, and CSIRO's Parkes telescope in Australia. view more (2009-05-22)
In Unique Stellar Laboratory, Einstein's Theory Passes Strict, New Test Taking advantage of a unique cosmic configuration, astronomers have measured an effect predicted by Albert Einstein's theory of General Relativity in the extremely strong gravity of a pair of superdense neutron stars. Essentially, the famed physicist's 93-year-old theory passed yet another test. view more (2008-07-07)
Star eats companion ESA's Integral space observatory, together with NASA's Rossi X-ray Timing Explorer spacecraft, has found a fast-spinning pulsar in the process of devouring its companion. view more (2005-09-07)
First view of a newborn millisecond pulsar? Combining Hubble Space Telescope images with radio observations has revealed a highly unusual system consisting of a fast spinning pulsar and a bloated red companion star. The existence of the system is something of a mystery - the best explanation so far is that we have our first view of a millisecond pulsar just after it has been `spun up` by... view more...

Researchers using Arecibo Telescope discover never-before-seen pulsar blasts in Crab Nebula Astronomers and physicists using the Cornell-managed Arecibo Telescope in Puerto Rico have discovered radio interpulses from the Crab Nebula pulsar that feature never-before-seen radio emission spectra. This leads scientists to speculate this could be the first cosmic object with a third magnetic pole. view more (2007-01-09)
GLAST Observatory renamed for Fermi, reveals entire gamma-ray sky The U.S. Department of Energy (DOE) and NASA announced today that the Gamma-Ray Large Area Space Telescope (GLAST) has revealed its first all-sky map in gamma rays. view more (2008-08-27)
First gamma-ray-only pulsar observation opens new window on stellar evolution About three times a second, a 10,000-year-old stellar corpse sweeps a beam of gamma-rays toward Earth. view more (2008-10-17)
White Dwarf Pulses Like a Pulsar New observations from Suzaku, a joint Japanese Aerospace Exploration Agency (JAXA) and NASA X-ray observatory, have challenged scientists' conventional understanding of white dwarfs. Observers had believed white dwarfs were inert stellar corpses that slowly cool and fade away, but the new data tell a completely different story. view more (2008-01-03)
Astronomers weigh 'recycled' millisecond pulsar A team of U.S. and Australian astronomers is announcing today that they have, for the first time, precisely measured the mass of a millisecond pulsar - a tiny, dead star spinning hundreds of times every second. view more (2006-01-13)
Integral reveals new class of 'supergiant' X-ray binary stars ESA's Integral gamma-ray observatory has discovered a new, highly populated class of X-ray fast 'transient' binary stars, undetected in previous observations. view more (2005-11-17)
Pulsar find boosts hope for gravity-wave hunters Neutron star pairs may merge and give off a burst of gravity waves about six times more often than previously thought, scientists report in today's issue of the journal Nature [4 December]. If so, the current generation of gravity-wave detectors might be able to register such an event every year or two, rather than about once a decade - the most... view more... (2003-12-02)
NASA'S Fermi Telescope Discovers First Gamma-Ray-Only Pulsar About three times a second, a 10,000-year-old stellar corpse sweeps a beam of gamma-rays toward Earth. Discovered by NASA's Fermi Gamma-ray Space Telescope, the object, called a pulsar, is the first one known that only "blinks" in gamma rays. view more (2008-10-17)
