SUPERNOVA

Giant stars end their existence as a supernova. At violent explosions the atmosphere of the star is flung with speeds of several thousand kilometers per second to space.

Riesensterne beenden ihr Dasein als Supernova. Bei 
gewaltigen Explosionen wird die Gashülle des Sterns mit Geschwindigkeiten von 
mehreren tausend Kilometern pro Sekunde ins All geschleudert
 

M1 goes back presumably -- the Cancer nebulum, also known as M1, on a supernova which was watched in July 1054 of a Chinese astronomer. A pulsar is in the center of the nebulum.

This gloriously colorful nebulum arose CYGNUS LOOP -- at the appearance of a supernova, shock front on a relatively thick gas cloud

A discovered the Hubble space telescope this strange Ringstrucktur 1994 seven years after the appearance of the supernova 1987 ares in the big Magellanschen cloud in 1987.

Another star exploded N123D -- in the big Magelanschen cloud 3,000 years ago. Its remains are known under the name N123D.

The supernova Cassiopeia is more important CASSIOPEIA A than A back on a Sternenexplosion -- about 300 years ago. But although the explosion must have been able to be considered a bright star in the earthly sky, there aren't any reports of eyewitnesses.

CASSIOPEIA A
 

Cassiopeia A has grown to a 10 light years great bubble of 50 million degree hot gas in the meantime.

E0102 72-one supernova remains in the little Magellanschen cloud. The picture was put together from observations at different wavelengths.
blue = radiograph light (Chandra radiograph telescope)
green = visible light (Hubble space telescope)
red = radio signal (Australia telescope of compact Array)
