Radio pulses from pulsar appear to move faster than light
First ultraluminous pulsar: NuSTAR discovers impossibly bright dead star
Astronomers working with NASA's Nuclear Spectroscopic Telescope Array (NuSTAR), led by Caltech's Fiona Harrison, have found a pulsating dead star beaming with the energy of about 10 million suns. The object, ...
Gravitational waves help understand black hole weight gain
Supermassive black holes: every large galaxy's got one. But here's a real conundrum: how did they grow so big?
A planet made of diamond (w/ video)
A once-massive star that's been transformed into a small planet made of diamond: that is what University of Manchester astronomers think they've found in the Milky Way.
Astronomers use vanishing neutron star to measure space-time warp
In an interstellar race against time, astronomers have measured the space-time warp in the gravity of a binary star and determined the mass of a neutron star—just before it vanished from view.
Pulsar in stellar triple system makes unique gravitational laboratory
Astronomers using the National Science Foundation's Green Bank Telescope (GBT) have discovered a unique stellar system of two white dwarf stars and a superdense neutron star, all packed within a space smaller ...
IGR J11014-6103: Chandra sees runaway pulsar firing an extraordinary jet
(Phys.org) —NASA's Chandra X-ray Observatory has seen a fast-moving pulsar escaping from a supernova remnant while spewing out a record-breaking jet—the longest of any object in the Milky Way galaxy—of ...
Mysterious pulsar with hidden powers discovered
Dramatic flares and bursts of energy - activity previously thought reserved for only the strongest magnetized pulsars - has been observed emanating from a weakly magnetised, slowly rotating pulsar. The international ...
Fermi finds a 'transformer' pulsar
(Phys.org) —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 beacon vanished, while at ...
New 'fix' for cosmic clocks could help uncover ripples in space-time
An international team of scientists including University of British Columbia astronomer Ingrid Stairs has discovered a promising way to fine-tune pulsars into the best precision time-pieces in the Universe.
The music of gravitational waves
A team of scientists and engineers at NASA's Jet Propulsion Laboratory has brought the world one step closer to "hearing" gravitational waves -- ripples in space and time predicted by Albert Einstein in the ...
Neutron stars in the computer cloud
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 ...
Pushing the envelope
(PhysOrg.com) -- G327.1-1.1 is the aftermath of a massive star that exploded as a supernova in the Milky Way galaxy.
Chameleon pulsar baffles astronomers
A pulsar that is able, without warning, to dramatically change the way in which it shines has been identified by an international team of astronomers.
