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)

Young supernova remnants not dusty enough, according to UC Berkeley astronomers
One of the youngest supernova remnants known, a glowing red ball of dust created by the explosion 1,000 years ago of a supermassive star in a nearby galaxy, the Small Magellanic Cloud, exhibits the same problem as exploding stars in our own galaxy: too little dust.   view more (2006-06-07)

Discovery of Giant X-ray Loop Hints at Cosmic Particle Accelerator
Astronomers have found a vast loop-like structure, 20 light years across, adjacent to the most massive star-forming region known in our galaxy. The loop, which was observed in X-ray wavelengths, is 15 times the size of the Arches Cluster, a star-forming region close to the centre of the Milky Way.... view more (2005-03-31)

Integral identifies supernova rate for Milky Way
Using ESA's Integral observatory, an international team of researchers has been able to confirm the production of radioactive aluminium (Al 26) in massive stars and supernovae throughout our galaxy and determine the rate of supernovae-one of its key parameters.   view more (2006-01-09)

ESA's XMM-Newton makes the first measurement of a dead star's magnetism
Using the superior sensitivity of ESA's X-ray observatory, XMM-Newton, a team of European astronomers has made the first direct measurement of a neutron star's magnetic field. The results provide deep insights into the extreme physics of neutron stars and reveal a new mystery yet to be solved... view more (2003-06-11)

Supernova leaves behind mysterious object
Thanks to data from ESA's XMM-Newton satellite, a team of scientists taking a closer look at an object discovered over 25 years ago have found that it is like none other known in our galaxy.   view more (2006-07-10)

The Weirdest Type Ia Supernova Yet
A group of scientists affiliated with the SuperNova Legacy Survey (SNLS) have found startling evidence that there is more than one kind of Type Ia supernova, a class of exploding stars which until now has been regarded as essentially uniform in all important respects.   view more (2006-09-21)

Scientists find 'pinwheels' in Quintuplet cluster
Discovery of pinwheel-shaped dust spirals around two of the mysterious cocoon stars in the Quintuplet cluster tells scientists for the first time that they contain a duo of stars instead of just one.   view more (2006-08-21)

Astronomers discover new kind of black-hole explosion
Scientists have discovered what appears to be a new kind of cosmic explosion - a "hybrid gamma-ray burst" - which will be the subject of four articles to be published in the journal Nature on 21 December 2006.   view more (2006-12-21)

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)

Dark energy existed in infant universe
Using NASA's Hubble Space Telescope, researchers have discovered that dark energy, a mysterious repulsive force that makes the universe expand at an ever-faster rate, is not new but rather has been present in the universe for most of its 13-billion-year history.   view more (2006-11-17)

Einstein's dark energy accelerates the universe
The enigmatic "dark energy" that drives the acceleration of the Universe behaves just like Einstein's famed cosmological constant.   view more (2005-11-28)

Heavy Metal Stars: La Silla Telescope Detects Lots of Lead in Three Distant Binaries
Very high abundances of the heavy element Lead have been discovered in three distant stars in the Milky Way Galaxy. This finding strongly supports the long-held view that roughly half of the stable elements heavier than Iron are produced in common stars during a phase towards the end of their life... view more (2001-08-21)

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)

Biggest ever Gamma Ray search starts in Namibia
The world's most sensitive Gamma Ray telescopes are being inaugurated in Namibia (in Southwest Africa) on September 3rd. The High Energy Stereoscopic System (H.E.S.S.), a European/African collaboration in which the UK is a partner, will look for Gamma Rays produced by the most energetic particles... view more (2002-08-28)

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)

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)

A new unidentified very high energy gamma-ray source in our Galaxy
A European team based in Heidelberg (Germany) and their colleagues from the HEGRA collaboration have discovered a new, unidentified, very high energy gamma-ray source in our Galaxy. This source was detected via ground-based observations of the Imaging Atmosphere Cherenkov Telescope System.   view more (2004-12-14)

Astronomers detect echoes from ancient supernovae
A team of astronomers has found faint visible "echoes" of three ancient supernovae by detecting centuries-old light reflected by interstellar gas clouds hundreds of light-years removed from the original explosions.   view more (2005-12-22)

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)

XMM-Newton 'spare-time' provides impressive sky survey
For the past four years, while ESA's XMM-Newton X-ray observatory has been slewing between different targets ready for the next observation, it has kept its cameras open and used this spare time to quietly look at the heavens.   view more (2006-05-04)

BOSS: the Baryon Oscillation Spectroscopic Survey
The Sloan Digital Sky Survey (SDSS) uses a 2.5-meter telescope with a wider field of view than any other large telescope, located on a mountaintop in New Mexico called Apache Point and devoted solely to mapping the universe.   view more (2008-09-22)
