Cassiopeia, Milky Ways Youngest Supernova Poster

A quote from Desiderata by Max Ehrmann: And whether or not it is clear to you, no doubt the universe is unfolding as it should... to go with this amazing image from the Milky Way. This extraordinarily deep Chandra image shows Cassiopeia A (Cas A, for short), the youngest supernova remnant in the Milky Way. 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.
