Friday beautiful science

I was alerted about this image from Bad Astronomy.  Check this out:  

It shows a ribbon of gas, compressed and glowing due to a shock wave that slammed into it. The shock came from Supernova 1006, a star that detonated 7000 light years away from us. This was not a massive star that exploded, but a low-mass white dwarf, the dense core left over when a star like the Sun runs out of fuel. Still, the forces are roughly the same, with a titanic explosion ripping the star apart and creating eerie, unearthly beauty even in death.
