This image shows the remnants of a super nova, Cassiopeia A, or just Cas A. This super nova remnant is 11,000 light years away and is ever expanding in size. Right now, it's about 15 light years across and will continue to grow. The light from this super nova first reached Earth 330 years ago.This picture was taken with the NuSTAR X-ray telescope, which I have never heard of before. Because this was taken in the X-ray wavelength, these are not the super nova's true colors, but it still impressive looking none the less. The little hint of blue in the middle top of the explosion accents the super nova and gives is a little bit of uniqueness.
