Esa Science Technology Supernova Remnants Learn about the structure, stages, types and origin of supernova remnants, the result of stellar explosions. find out how they are related to cosmic rays, x ray emission and planet formation. Supernova remnants are very important to the structure of galaxies. they are a major source of heating of interstellar gas by means of the magnetic turbulence and violent shocks that they produce. they are the main source of most heavy elements, from oxygen on up.

Supernova remnants (snrs) are the ejected debris of supernova explosions from dying or dead stars. snrs form expanding shells, bows, or bubbles of highly engergized gas and interstellar material that are swept up in the shock wave. Supernova remnants will eventually disperse into the interstellar medium after around 100,000 years. during this time, they can look very similar to hii regions but will look very different in the radio spectrum. Check out this great page from the california institute of technology that will help stitch together our understanding of supernovae and the remnants they leave in their wake.

A supernova remnant is the leftover material from a massive star that has exploded in a supernova event. when a star reaches the end of its life cycle and can no longer support itself against gravity, it collapses under its own weight and explodes in a spectacular display of energy. Although only a small fraction of stars end their lives as supernovae, all supernovae leave behind a supernova remnant (snr), an expanding shock wave that interacts with the surrounding. This is a list of observed supernova remnants (snrs) in the milky way, as well as galaxies nearby enough to resolve individual nebulae, such as the large and small magellanic clouds and the andromeda galaxy and some nearby galaxies. The snr consists of material ejected in the supernova explosion itself, as well as other interstellar material that has been swept up by the passage of the shock wave from the exploded star.
