NASA's Swift Sees Double Supernova in Galaxy
In just the past six weeks, two supernovae have flared up in an obscure galaxy in the constellation Hercules. Never before have astronomers observed two of these powerful stellar explosions occurring in the same galaxy so close together in time.   view more (2007-06-27)

Space is dusty, and now astronomers know why
Massive star supernovae have been major "dust factories" ever since the first generations of stars formed several hundred million years after the Big Bang, according to an international study published in Science Express today.   view more (2006-06-09)

Supernovae-Cosmic Lighthouses
Supernovae stand out in the sky like cosmic lighthouses. Scientists at the Max Planck Institute for Astrophysics and at the National Astronomical Institute of Italy have now found a way to use these cosmic beacons to measure distances in space more accurately.   view more (2007-02-12)

The VLT Measures the Shape of a Type Ia Supernova
First Polarimetric Detection of Explosion Asymmetry has Cosmological Implications [1] An international team of astronomers [2] has performed new and very detailed observations of a supernova in a distant galaxy with the ESO Very Large Telescope (VLT) at the Paranal Observatory (Chile). They show... view more (2003-08-05)

XMM-Newton reveals the origin of elements in galaxy clusters
Deep observations of two X-ray bright clusters of galaxies with ESA's XMM-Newton satellite allowed a group of international astronomers to measure their chemical composition with an unprecedented accuracy.   view more (2006-05-11)

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)

Universe contains more calcium than expected
The universe contains one and a half times more calcium than previously assumed. This conclusion was drawn by astronomers of the SRON Netherlands Institute for Space Research, after observations with ESA's XMM-Newton X-ray observatory.   view more (2007-02-07)

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)

Scientists discover 'light echoes' of ancient supernovae
Astronomers have found "light echoes" from three ancient supernovae by detecting their faint, centuries-old light reflected in the clouds of interstellar dust.   view more (2005-12-23)

Massive-star supernovae found to be major space dust factories
An unaccounted for source of space dust which spawns life in the universe has been identified by an international team of scientists.   view more (2006-06-09)

Dark energy may be vacuum
Researchers at the University of Copenhagen's Dark Cosmology Centre at the Niels Bohr Institute have brought us one step closer to understanding what the universe is made of. As part of the international collaboration ESSENCE they have observed distant supernovae (exploding stars), some of which... view more (2007-01-17)

Clues To Supernova Origin Found In Dusty Stellar Wind
Scientists from Imperial College London have detected a dusty wind emitted by a star that, at the end of its life, turned into a white dwarf and then exploded as a supernova. This is the first time that a wind from this type of supernova precursor has been observed and it is also the first time... view more (2005-03-30)

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)

The Wild, Hidden Cousin of SN 1987A
Over a decade after it exploded, one of the nearest supernovae in the last 25 years has been identified. This result was made possible by combining data from the vast online archives from many of the world's premier telescopes.   view more (2008-09-26)

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)

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)

The quiet explosion
A European-led team of astronomers are providing hints that a recent supernova may not be as normal as initially thought. Instead, the star that exploded is now understood to have collapsed into a black hole, producing a weak jet, typical of much more violent events, the so-called gamma-ray bursts.   view more (2008-07-25)

Gamma-ray bursts: are we safe?
For a few seconds every day, Earth is bombarded by gamma rays created by cataclysmic explosions in distant galaxies. Such explosions, similar to supernovae, are known as 'gamma-ray bursts' or GRBs. Astronomers using ESA's X-ray observatory, XMM-Newton, are trying to understand the cause of these... view more (2003-09-17)

Two cosmic bursts upset tidy association between long gamma-ray bursts and supernovae
Two brilliant flashes of light from nearby galaxies are puzzling astronomers and could indicate that gamma-ray bursts, which signal the birth of a black hole, are more diverse than once thought.   view more (2006-12-21)

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)

Everyone wants gamma-ray eyes!
Even before ESA`s Integral gamma-ray observatory was launched, astronomers were competing to win time to use this state-of-the-art observatory. The Integral Science Operations Centre in Noordwijk, The Netherlands, received hundreds of excellent proposals. ESA expects Integral to revolutionise the... view more (2002-10-29)

VLT FLAMES Finds Hints of Helium-Richest Stars Ever Seen   view more (2005-03-15)

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)

Dark energy -- 10 years on
Three quarters of our universe is made up of some weird, gravitationally repulsive substance that was only discovered ten years ago - dark energy.   view more (2007-11-30)

Celebrating 5 years of the Very Large Telescope
From Sombreros to the Centre of the Milky Way Celebrating 5 years of the Very Large Telescope One of the world's most advanced telescope facilities, Very Large Telescope (VLT), situated in the Atacama Desert in Chile, celebrates its 5th birthday today (1st April 2004). During its short history the... view more (2004-03-31)
