Summary

DescriptionTycho xrayonly.jpg	English: X-ray & Optical images of Tycho - A long Chandra observation of Tycho has revealed a pattern of X-ray "stripes" never seen before in a supernova remnant. The stripes are seen in the high-energy X-rays (blue) that also show the blast wave, a shell of extremely energetic electrons. Low-energy X-rays (red) show expanding debris from the supernova explosion. The stripes, seen to the lower right of this image, may provide the first direct evidence that a cosmic event can accelerate particles to energies a hundred times higher than achieved by the most powerful particle accelerator on Earth.

Image title	A long Chandra observation of Tycho has revealed a pattern of X-ray stripes never seen before in a supernova remnant. The stripes are seen in the high-energy X-rays (blue) that also show the blast wave, a shell of extremely energetic electrons. Low-energy X- rays (red) show expanding debris from the supernova explosion. The stripes, seen to the lower right of this composite image that includes optical data from the Digitized Sky Survey, may provide the first direct evidence that a cosmic event can accelerate particles to energies a hundred times higher than achieved by the most powerful particle accelerator on Earth.
