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)
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)
A young pulsar shows its hand
A small, dense object only twelve miles in diameter is responsible for this beautiful X-ray nebula that spans 150 light years. view more (2009-04-06)
Stellar forensics with striking new image from Chandra
A spectacular new image shows how complex a star's afterlife can be. By studying the details of this image made from a long observation by NASA's Chandra X-ray Observatory, astronomers can better understand how some stars die and disperse elements like oxygen into the next generation of stars and planets. view more (2007-10-24)
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)
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)
Neutron stars can be more massive, while black holes are more rare, Arecibo Observatory finds
Neutron stars and black holes aren't all they've been thought to be. In fact, neutron stars can be considerably more massive than previously believed, and it is more difficult to form black holes, according to new research developed by using the Arecibo Observatory in Arecibo, Puerto Rico. view more (2008-01-15)
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)
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)
General relativity survives gruelling pulsar test — Einstein at least 99.95 percent right
An international research team led by Prof. Michael Kramer of the University of Manchester's Jodrell Bank Observatory, UK, has used three years of observations of the "double pulsar", a unique pair of natural stellar clocks which they discovered in 2003, to prove that Einstein's theory of general relativity-the theory of gravity that... view more...

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)
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)
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)
`Quiet` star wasn`t quiet after all, say astronomers
For more than two years the star was `quiet`. Or so astronomers thought. But the X-ray pulsar EXO 2030+375 was abuzz with activity. Scientists simply lacked the ability to `hear` it over the hum of a nearby black hole. Now a study by scientists at the University of Southampton, the National Space Science and Technology Center (NSSTC) in... view more... (2002-07-10)
Milky Way's fastest pulsar is on its way out of the galaxy, astronomers find
The Milky Way's fastest observed pulsar is speeding out of the galaxy at more than 670 miles a second, propelled largely by a kick it received at its birth 2.5 million years ago. view more (2006-02-16)
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)
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)
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)
