Supernova's ghost caught expanding in new video

This new movie of the supernova remnant Cassiopeia A was made by combining Chandra X-ray satellite observations taken in January 2000, February 2002, February 2004 and December 2007. The debris is expanding more slowly than expected, probably because the energy of the explosion is being used to magnetically accelerate particles, turning them into cosmic rays

What you have here is an animation construxcted from four still frames taken over a 7 year period. The pictures are of X-Rays, shifted down into the visible color band by a computer. It depicts the super-hot gasses of the explosion expanding into the space around the former star. The supernova appeared on Earth in 1667, and was possibly observed only by John Flamsteed, who thought it was a normal star. It is about 10,000 ly away.

anyone come from minecraft? I need some directions on how to get back.....

Wow. It's got to be moving pretty damn fast, relatively to how large space is. Imagine that centimeter the pic just moved- that's probably equivalent to millions of miles...and in the span of less than a decade. Pretty damn fast my friends!

@shadowhacks35 Exactly the same.
