Cassiopeia A comes alive across time and space
Two new efforts have taken a famous supernova remnant from the static to the dynamic. A new movie of data from NASA's Chandra X-ray Observatory shows changes in time never seen before in this type of object. A separate team will also release a dramatic three-dimensional visualization of the same remnant. view more (2009-01-06)
Physicists discover Guy Fawkes would have devastated Westminster
Had the gunpowder plot succeeded, Guy Fawkes would not only have destroyed the old palace of Westminster but would have caused chaos and devastation across central London, destroying Westminster Hall, the Abbey and the streets immediately surrounding them with structural damage being caused to buildings as far away as Whitehall. Physicists have... view more... (2003-11-04)
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)
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)
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...

TU Delft and TNO combine knowledge of explosive reactions
The explosions group of TU Delft and TNO-PML are starting an intensive co-operative research programme in the field of explosion safety. Their knowledge will be combined in the 'Knowledge Centre for Reactive Gas-dynamics and Explosion Safety,' which opens on 18 July 2001. The knowledge and experience of both research groups is especially... view more... (2001-07-17)
Astronomers Unravel Mystery of Gamma Ray Bursts
The cause of gamma ray bursts, the most violent and explosive events in the Universe, has remained a mystery since they were first discovered in 1967. Now a team of scientists, led by astronomers from the University of Leicester, believes they have found an answer to the puzzle. Their research results [published in `Nature` on 4th April] indicate... view more... (2002-04-04)
Particles as tracers for the most massive explosions in the Milky Way
Astronomers recently observed a mysterious flux of particles in the universe, and the hope was born that this may be the first observation of the remnants of "dark matter". view more (2009-08-11)
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 about the end of this star's life. A neutron star is... view more... (2003-06-11)
Hotter than expected neutron star surfaces help explain superburst frequency
A new theoretical thermometer built from heavy-duty mathematics and computer code suggests that the surfaces of certain neutron stars run significantly hotter than previously expected. Hot enough, in fact, to at least partially answer an open question in astrophysics — how to explain the observed frequency of ultra-violent explosions known... view more... (2007-04-16)
'Naked-eye' gamma-ray burst was aimed squarely at Earth
Data from satellites and observatories around the globe show a jet from a powerful stellar explosion witnessed March 19 was aimed almost directly at Earth. view more (2008-09-12)
Nuclear explosion on a dead star - astronomers probe aftermath
A team of astronomers from the UK and Germany have found that a nuclear explosion on the surface of a star 5,000 light years from Earth resulted in a blast wave moving at over 1,700 km per second (one thousand miles per second or almost four million miles per hour!). view more (2006-07-20)
XMM-Newton uncovers a celestial Rosetta stone
ESA's XMM-Newton orbiting X-ray telescope has uncovered a celestial Rosetta stone: the first close-up of a white dwarf star, circling a companion star, that could explode into a particular kind of supernova in a few million years. view more (2009-09-04)
1843 stellar eruption may be new type of star explosion
Eta Carinae, the galaxy's biggest, brightest and perhaps most studied star after the sun, has been keeping a secret: Its giant outbursts appear to be driven by an entirely new type of stellar explosion that is fainter than a typical supernova and does not destroy the star. view more (2008-09-11)
Robotic telescope unravels mystery of cosmic blasts
Scientists have used the world's largest robotic telescope to make the earliest-ever measurement of the optical polarisation* of a Gamma Ray Burst (GRB) just 203 seconds after the start of the cosmic explosion. This finding, which provides new insight into GRB physics, is published in Science today (15th March 2007). view more (2007-03-19)
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)
Infrared Echoes Give NASA's Spitzer a Supernova Flashback
Hot spots near the shattered remains of an exploded star are echoing the blast's first moments, say scientists using data from NASA's Spitzer Space Telescope. view more (2008-10-02)
Spectacular Views Of An Exploding Star
An astronomer from the Isaac Newton Group of Telescopes has obtained spectacular images of the star V838 Monocerotis which became the brightest in our Galaxy when it exploded in January 2002. One of the images will be highlighted on the front cover of the journal Nature on 27 March 2003 and in a research paper published in the same issue. V838... view more... (2003-03-27)
Hubble's 17th anniversary -- extreme star birth in the Carina Nebula
Hubble's new view of the Carina Nebula shows the process of star birth at a new level of detail. view more (2007-04-25)
Star on a Hubble diet
How heavy can a star be? This conundrum has haunted astronomers for decades. Theory indicates that there should be an upper stellar mass limit somewhere between 120 and 300 solar masses. Even though heavy stars are very bright, measurements of their masses can be complicated. view more (2006-12-12)
