LIGO observations probe the dynamics of the crab pulsar
The search for gravitational waves has revealed new information about the core of one of the most famous objects in the sky: the Crab Pulsar in the Crab Nebula.   view more (2008-06-03)

CSI: Milky Way team works scene of dead star
Like a team of forensic detectives in a television show that could be called "CSI: Milky Way," a University of Chicago astrophysicist and his associates are piecing together how a mysterious infrared ring got left around a dead star that displays a magnetic field trillions of times more... view more (2008-05-29)

Scientists Find Giant Ring Encircling Exotic Dead Star
One of the most powerful eruptions in the universe might have spun an infrared ring around a rare and exotic star known as a magnetar, a highly magnetized neutron star and the remnant of a brilliant supernova explosion signaling the death throes of a massive star.   view more (2008-05-29)

Supernova birth seen for first time
Astronomers have seen the aftermath of spectacular stellar explosions known as supernovae before, but until now no one has witnessed a star dying in real time.   view more (2008-05-22)

A scientific first: A supernova explosion is observed in real time
An ordinary observation with NASA's Swift research satellite recently led to the first real-time sighting of a star in the process of exploding. Astronomers have surveyed thousands of these supernova explosions in the past, but their observations have always begun some time after the main event is... view more (2008-05-22)

Observation of X-rays from birth of supernova leads to all-out effort to record stellar death
The lucky capture in January of an X-ray outburst from the very beginning of a supernova allowed astronomers around the world to quickly follow up with ground-based telescopes and collect a wealth of new information on early processes in stellar explosions, according to a paper newly submitted to... view more (2008-05-22)

NASA's Swift satellite catches first 'normal' supernova in the act of exploding
Thanks to a fortunate observation with NASA's Swift satellite, astronomers, for the first time, have caught a normal supernova at the moment of its birth--the first instant when an exploding star begins spewing its energy into space, transforming into a supernova that during its brief lifetime will... view more (2008-05-22)

Discovery of most recent supernova in our galaxy
The most recent supernova in our Galaxy has been discovered by tracking the rapid expansion of its remains. This result, using NASA's Chandra X-ray Observatory and NRAO's Very Large Array (VLA), has implications for understanding how often supernovas explode in the Milky Way galaxy.   view more (2008-05-15)

Milky Way's Giant Black Hole Awoke from Slumber 300 Years Ago
Using NASA, Japanese, and European X-ray satellites, a team of Japanese astronomers has discovered that our galaxy's central black hole let loose a powerful flare three centuries ago.   view more (2008-04-16)

New Star Systems First of Their Kind
Researchers funded by the National Science Foundation (NSF) announced today in Astrophysical Journal Letters that they have discovered a faraway binary star system that could be the progenitor of a rare type of supernova.   view more (2008-04-02)

Action Replay of Powerful Stellar Explosion
Astronomers have made the best ever determination of the power of a supernova explosion that was visible from Earth long ago. By observing the remnant of a supernova and a light echo from the initial outburst, they have established the validity of a powerful new method for studying supernovas.   view more (2008-03-24)

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)

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)

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)

Supernova remnants dance in the LMC
The Gemini South Multi-Object Spectograph (GMOS) recently captured a dramatic image of a vast cloud complex named DEM L316 located in the Large Magellanic Cloud.   view more (2008-01-11)

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... view more (2008-01-03)

Chandra discovers cosmic cannonball
One of the fastest moving stars ever seen has been discovered with NASA's Chandra X-ray Observatory. This cosmic cannonball is challenging theories to explain its blistering speed.   view more (2007-11-29)

Texas A&M researchers examine Einstein's theories on the universe
Einstein's self-proclaimed "biggest blunder" - his postulation of a cosmological constant (a force that opposes gravity and keeps the universe from collapsing) - may not be such a blunder after all, according to the research of an international team of scientists that includes two Texas... view more (2007-11-28)

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... view more (2007-10-24)

NASA: Major Step Toward Knowing Origin of Cosmic Rays
Recent observations from NASA and Japanese X-ray observatories have helped clarify one of the long-standing mysteries in astronomy -- the origin of cosmic rays.   view more (2007-10-10)

Mysterious energy burst stuns astronomers
In a shock finding, astronomers using CSIRO's Parkes telescope have detected a huge burst of radio energy from the distant universe that could open up a new field in astrophysics.   view more (2007-09-28)

'Beyond Einstein' research should begin with mission to study dark energy
NASA and the U.S. Department of Energy should pursue the Joint Dark Energy Mission (JDEM) as the first mission in the "Beyond Einstein" program, according to a new report from the National Research Council.   view more (2007-09-07)

Shrinking giants, exploding dwarves
When white dwarf stars explode, they leave behind a rapidly expanding cloud of 'stardust' known as a Type Ia supernova. These exploding events, which shine billions of times brighter than our sun, are all presumed to be extremely similar, and thus have been used extensively as cosmological... view more (2007-08-28)

Possible closest neutron star to Earth found
Using NASA's Swift satellite, McGill University and Penn State University astronomers have identified an object that is likely one of the closest neutron stars to Earth -- and possibly the closest.   view more (2007-08-21)

Star light, star bright: FSU facility duplicating conditions of supernovas
How is matter created? What happens when stars die? Is the universe shrinking, or is it expanding? For decades, scientists have been looking for answers to such "big picture" questions.   view more (2007-08-15)
