Rippling Crab Nebula Rate Topic:

see this short movie
made from timelapse shots of Crab
http://chandra.harva...nedmovie_sm.mov

here are other movies of Crab
http://chandra.harva...052/movies.html

advise you select the low resolution version so it takes less time to download and let the download happen in the background while u do something else. it takes several minutes
but then u can come back and play it

"This movie shows dynamic rings, wisps and jets of matter and antimatter around the pulsar in the Crab Nebula as observed in X-ray light by Chandra (left, blue) and optical light by Hubble (right, red)."

Yeah, I have to admit, that looks pretty damn good. Makes me wish I'd taken physics ;)

That looks like waves in the water. What is that?

The expansion of the leftovers from a supernova that was observed in 1054 A.D. Basically it's the gas that got blown off, and the rippling is, I expect, from a compression wave travelling through the nebula.
