Wind socks, bow shocks, shockwaves and collisions are often used to describe the phenomena that create high-frequency electromagnetic radiation in the cosmos

From gamma rays down through X-rays and extreme ultraviolet, conventional theories have relied upon gravity and acceleration as the only way for them to be produced in space.

Compression of hydrogen gas and dust is supposed to create enough transfer of momentum that it reaches temperatures greater than the cores of some stars. In other words, it is the high temperature of the gas that makes it glow so brightly.

The CHANDRA satellite has detected streams of charged material pouring out of the Crab Nebula, emitting X-rays as they go. It was long thought that nebular clouds or the expanding gases of supernova explosions could not be sources of those frequencies, since the bubbles were supposed to be areas where gases were losing kinetic energy and cooling off. However, several “mysterious” observations have called into question the underlying principles of standard theory.....................
