SUMMARY: European astronomers have produced the first image of an object using high energy gamma rays - the most penetrating form of radiation known. The image is of a supernova remnant called RX J1713.7-3946, which exploded 1,000 years ago. Over time, a ring of material has expanded to twice the diameter of the Moon in the sky. If you had gamma ray eyes, you would be able to see a large ring in the sky every night. This also helps solve a 100 year mystery about the origin of cosmic rays; the remnant seems to be acting as a particle accelerator.

SUMMARY: European astronomers have produced the first image of an object using high energy gamma rays - the most penetrating form of radiation known. The fact that imaging can be done with gamma rays is truly amazing, and, no doubt, fraught with deceptability. Gamma rays from 9 to 12 billion years ago must be much easier with all that redening.
