Watch the Crab Nebula Expand Over a 13 Year Period

The Bad Astronomer writes "A thousand years ago, the light from the explosion of a massive star reached the Earth. We now call this supernova remnant the Crab Nebula, and a new image of the Crab taken by astronomer Adam Block shows the physical expansion of the debris, made obvious in a short video comparing his 2012 observations with some taken in 1999. The outward motion of filaments and knots in the material can be easily traced even over this relatively short time baseline."

    LAME!!! just 2 exposures alternating back and forth.

    The newer one picks up more of the blue, so it looks larger. If you watch the red, it is definitely moving outward. Will have to use this the next time I teach about nebula.

    Plus the biggest changes seem to be in the colors not the growth which might be related to the fact it was taken by two different telescopes....

    Ahh yes, a couple of loud mouth idiots from a church yelled at a couple of loud mouth idiots from another church, imagine that! Such a coincidence this happened at the same time as the Crab Nebula exploding.
