Cosmic accelerator
Cosmic rays from our Milky Way galaxy are accelerated efficiently in the remnants of an exploded star, as shown in this June 25 imagery from the European Southern Observatory's Very Large Telescope and NASA's Chandra X-ray Observatory. Researchers studied the color-coded emissions from the supernova remnant RCW 86, which is 8,200 light-years from Earth, to learn how such "super-accelerators" work. They found that the shock wave created by the stellar explosion moves at 1 to 3 percent of the speed of light.
