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 properties of the wind hold vital clues to the kind of star... 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 lives. When a new gamma ray burst (GRB 030329) was...

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)
Astronomers discover new kind of supernova
Supernovae were always thought to occur in two main varieties. But a team of astronomers including Carnegie's Wendy Freedman, Mark Phillips and Eric Persson is reporting the discovery of a new type of supernova called Type Iax. View More (2013-03-27)
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 supernova, caused by the explosion of a "white dwarf", a... 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)
Forecasting a supernova explosion
Type II supernovae are formed when massive stars collapse, initiating giant explosions. It is thought that stars emit a burst of mass as a precursor to the supernova explosion. View More (2013-02-07)
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)
University of Toronto physicists create supernova in a jar
A team of physicists from the University of Toronto and Rutgers University have mimicked the explosion of a supernova in miniature. View More (2010-12-03)
Observed: The outburst before the blast
Before they go all-out supernova, certain large stars undergo a sort of "mini-explosion," throwing a good-sized chunk of their material off into space. View More (2013-02-07)
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 astronomers.

Hubble spots a celestial bauble
Hubble has spotted a festive bauble of gas in our neighbouring galaxy, the Large Magellanic Cloud. Formed in the aftermath of a supernova explosion that took place four centuries ago, this sphere of gas has been snapped in a series of observations made between 2006 and 2010. View More (2010-12-15)
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)
In a star's final days, astronomers hunt 'signal of impending doom'
An otherwise nondescript binary star system in the Whirlpool Galaxy has brought astronomers tantalizingly close to their goal of observing a star just before it goes supernova. View More (2011-12-01)
Supernova Explosions Stay In Shape
At a very early age, children learn how to classify objects according to their shape. Now, new research suggests studying the shape of the aftermath of supernovas may allow astronomers to do the same. View More (2009-12-18)
Life and death in a star-forming cloud
The aftershock of a stellar explosion rippling through space is captured in this new view of supernova remnant W44, which combines far-infrared and X-ray data from ESA's Herschel and XMM-Newton space observatories. View More (2012-11-15)
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 the Universe.
