One of the most energetic explosive events known is a supernova. ... This will cause a blast wave that ejects the star's envelope into interstellar space.

Chandra Views a Supernova Remnant in the Making ... The photo on the left was taken in 1987 during the supernova explosion of SN 1987A, while the right hand photo was taken beforehand.

"We think that jets cause a major class of supernova explosions." ... If a supernova's light is expanding uniformly in all directions, there is no polarization. There will be measurable polarization

A simple, analytic model was developed at the Max-Planck-Institute for Astrophysics to discuss the complex processes which cause the supernova explosions of massive stars.

Gamma-ray bursts are the most powerful explosions ever detected in the Universe. ... "We can now confidently say that the death of a massive star, a supernova, was the cause of a gamma-ray burst.

What causes the supernova to blow up is that gravity gives the supernova it's energy. Once the core has gained so much mass that it can't withstand it's own weight, the core implodes.

Gamma-ray bursts are the most powerful explosions ever detected in the Universe. ... "We can now confidently say that the death of a massive star, a supernova, was the cause of a gamma-ray burst.

ESA's XMM-Newton is the most sensitive X-ray telescope ever built. Its high-technology design uses over 170 wafer-thin ... Its orbit takes it almost a third of the way to the Moon, ... 4 April 2002

Gamma-ray bursts are the most powerful explosions ever detected in the Universe. ... "We can now confidently say that the death of a massive star, a supernova, was the cause of a gamma-ray burst.

A supernova (pl. supernovae ) is a stellar explosion. Supernovae are extremely luminous and cause a burst of radiation that often briefly outshines an entire galaxy, before fading from view over several weeks or months. During this short interval, a supernova can radiate as much...
