XMM-Newton's anniversary view of supernova SN 1987A
Twenty years after the first detection of SN 1987A, the nearest supernova ever detected since the invention of the telescope, XMM-Newton provided a fresh-new view of this object. The source keeps brightening-XMM-Newton confirms. view more (2007-02-26)
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 that associated dust has been detected. The... view more... (2005-03-30)
CERN scientists predict supernova
A team of theoretical physicists working at CERN and the Technion Institute of Technology in Israel has developed a theory to account for the mysterious gamma ray bursts that come from the depths of the Universe. According to their ideas, gamma ray bursts are linked to supernovae, the cataclysmic explosions of massive stars at the end of their... view more... (2003-04-15)
Twin Star Explosions Fascinate Astronomers
Scientists using NASA's Swift satellite stumbled upon a rare sight, two supernovas side by side in one galaxy. view more (2006-11-21)
Supernova remnant menagerie
The supernova remnant N 63A is a member of N 63, a star-forming region in the Large Magellanic Cloud (LMC). Visible from the southern hemisphere, the LMC is an irregular galaxy lying 160,000 light-years from our own Milky Way galaxy. view more (2005-06-07)
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)
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 for the first time that a particular type of... view more... (2003-08-05)
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)
Cassiopeia A - The colorful aftermath of a violent stellar death
A new image taken with the NASA/ESA Hubble Space Telescope provides a detailed look at the tattered remains of a supernova explosion known as Cassiopeia A (Cas A). It is the youngest known remnant from a supernova explosion in the Milky Way. view more (2006-08-30)
A Strange Supernova with a Gamma-Ray Burst
On April 25, the BeppoSAX satellite detected a Gamma-Ray Burst from the direction of the constellation Telescopium, deep in the southern sky. Although there is now general consensus that they originate in very distant galaxies, the underlying physical causes of these events that release great amounts of energy within seconds are still puzzling... view more...

NC State Researchers
Researchers at North Carolina State University have used a mathematical model that allows them to get a clearer picture of the galaxy's youngest supernova remnant by correcting for the distortions caused by cosmic dust. view more (2009-04-23)
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 reference beacons to trace distance and the evolution of... view more...

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)
Peculiar, junior-sized supernova discovered by New York teen
In November 2008, Caroline Moore, a 14-year-old student from upstate New York, discovered a supernova in a nearby galaxy, making her the youngest person ever to do so. view more (2009-06-11)
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)
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)
Superbubble of supernova remnants caught in act of forming
A superbubble in space, caught in the act of forming, can help scientists better understand the life and death of massive stars, say researchers at the University of Illinois at Urbana-Champaign. view more (2007-01-10)
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)
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)
New laser technique may help find supernova
One single atom of a certain isotope of hafnium found on Earth would prove that a supernova once exploded near our solar system. view more (2009-08-12)
