A star's death comes to light
Using NASA's Chandra X-ray Observatory, scientists have created a stunning new image of one of the youngest supernova remnants in the galaxy. This new view of the debris of an exploded star helps astronomers solve a long-standing mystery, with implications for understanding how a star's life can... view more (2007-01-10)

ESA`s Integral satellite ready for lift-off from Baikonur

Flares illuminate the secret life of a quiescent black hole
Astronomers probing the intimate details of apparently quiescent stellar black holes have discovered that in reality they are dynamic, lively places, subject to flares that briefly illuminate the whole of the gas disc around the black hole. Their observations are helping to build up a picture of... view more (2002-04-04)

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)

A 'wild cousin' emerges from family tree of exploding stars
Astronomers may have discovered the relative of a freakishly behaving exploding star once thought to be the only one of its kind.   view more (2008-09-26)

New technique for 'weighing' black holes
ESA's XMM-Newton has helped to find evidence for the existence of controversial Intermediate Mass Black Holes. Scientists used a new, recently proven method for determining the mass of black holes.   view more (2007-05-17)

Orphan stars found in long galaxy tail
Astronomers have found evidence that stars have been forming in a long tail of gas that extends well outside its parent galaxy. This discovery suggests that such "orphan" stars may be much more prevalent than previously thought.   view more (2007-09-21)

Lensless camera uses X-rays to view nanoscale materials and biological specimens
X-rays have been used for decades to take pictures of broken bones, but scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory and their collaborators have developed a lensless X-ray technique that can take images of ultra-small structures buried in nanoparticles and... view more (2008-02-20)

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)

New Evidence Links Stellar Remains to Oldest Recorded Supernova
The new study shows that the supernova remnant RCW 86 is much younger than previously thought. As such, the formation of the remnant appears to coincide with a supernova observed by Chinese astronomers in 185 A.D. The study used data from NASA's Chandra X-ray Observatory and the European Space... view more (2007-01-05)

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)

Scientists piece together the most distant cosmic explosion
In this week's issue of Nature, scientists at Penn State University and their U.S. and European colleagues discuss how this explosion, detected on 4 September 2005, was the result of a massive star collapsing into a black hole.   view more (2006-03-09)

Exploding star takes astronomers by surprise
A partially exploding star, known as a nova, has recovered more quickly than expected, say scientists who have analysed new data from the ESA`s XMM-Newton X-ray satellite. Nova explosions are not completely destructive phenomena. In fact, after an explosion occurs, the star recovers and starts... view more (2002-10-11)

Mystery spiral arms explained?
Using a trio of space observatories, astronomers may have cracked a 45-year old mystery surrounding two ghostly spiral arms in the galaxy M106 (NGC 4258).   view more (2007-04-11)

New X-ray microbeam answers 20-year-old metals question
What happens to metals when you bend them? The question isn't as easy as you may think. A research team from the National Institute of Standards and Technology (NIST), Oak Ridge National Laboratory (ORNL), and the University of Southern California, using a unique X-ray probe, has gathered the first... view more (2006-08-07)

A new method to weigh giant black holes
How do you weigh the biggest black holes in the universe? One answer now comes from a new and independent technique that UC Irvine scientists and other astronomers have developed using data from NASA's Chandra X-ray Observatory.   view more (2008-07-17)

Zooming in on the protein-conducting channel
Researchers have gained the most detailed view yet of the heart of the translocon, a channel through which newly constructed proteins are inserted into the cell membrane.   view more (2005-11-17)

Astronomers Pioneer New Method For Probing Exotic Matter
Using European and Japanese/NASA X-ray satellites, astronomers have seen Einstein's predicted distortion of space-time around three neutron stars, and in doing so they have pioneered a groundbreaking technique for determining the properties of these ultradense objects.   view more (2007-08-28)

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)

GALAXY CLUSTERS, NEAR AND FAR, HAVE A LOT IN COMMON

ORNL mirrors powerful tools for studying micro-, nano-materials
Precision mirrors to focus X-rays and neutron beams could speed the path to new materials and perhaps help explain why computers, cell phones and satellites go on the blink.   view more (2005-07-21)

The case of the neutron star with a wayward wake
A long observation with NASA's Chandra X-ray Observatory revealed important new details of a neutron star that is spewing out a wake of high-energy particles as it races through space.   view more (2006-06-02)

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)

Europe opens a window onto a violent Universe
ESA PR 66-2002. The European Space Agency has today launched a new observatory set to revolutionise the branch of astrophysics that seeks to unravel the secrets of the highest-energy - and therefore the most violent - phenomena in the Universe. This comes 20 years after the end of ESA`s COS-B... view more (2002-10-17)

Chandra independently determines Hubble constant
A critically important number that specifies the expansion rate of the Universe, the so-called Hubble constant, has been independently determined using NASA's Chandra X-ray Observatory.   view more (2006-08-10)
