Name, Cassiopeia, Milky Ways Youngest Supernova Gift Wrapping Paper
tagged with: star galaxies, outer space picture, supernova explosion, supernovae remnant, milky way youngest supernova, cosmic ray, neutron star, cassasn, deep space astronomy, cassiopeia
Galaxies, Stars and Nebulae series This extraordinarily deep Chandra image shows Cassiopeia A (Cas A, for short), the youngest supernova remnant in the Milky Way. New analysis shows that this supernova remnant acts like a relativistic pinball machine by accelerating electrons to enormous energies. The blue, wispy arcs in the image show where the acceleration is taking place in an expanding shock wave generated by the explosion. The red and green regions show material from the destroyed star that has been heated to millions of degrees by the explosion.
Astronomers have used this data to make a map, for the first time, of the acceleration of electrons in a supernova remnant. Their analysis shows that the electrons are being accelerated to almost the maximum theoretical limit in some parts of Cas A. Protons and ions, which make up the bulk of cosmic rays, are expected to be accelerated in a similar way to the electrons. Therefore, this discovery provides strong evidence that supernova remnants are key sites for energizing cosmic rays.

Galaxies, Stars and Nebulae series A beautiful space photograph featuring the 7500 light year distant Carina Nebula. This Hubble image shows rich, interstellar gas clouds feeding the formation of new stars. As a proto star forms, the gas clouds get dragged to its surface and some gets emitted as tight jets of material travelling at hundreds of miles per second. These in turn help sculpt the gas clouds into weird and grotesque shapes, some looking like strange worms, swimming through space.
