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....
Technology, the cause of and solution to all of life's problems.
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.
Off topic but I really am annoyed with the hack web "programmers" that build web sites with a dozen or more cross site scripts. Here's the shit list from this latest atrocity:
facebook.com
google.com
google-analytics.com
outbrain.com
parsley.com
chartbeat.com
criteo.com
vimeo.com
twitter.com
washingtonpost.com
revsci.net
adsonar.com
cleanprint.com
wapolabs.com
grvcdn.com
echoenabled.com
content.ad
googleapis.com
amazon-adsystem.com
visualrevenue.com
vimeocdn.com
slate.com
That's 21 external javascript sites. There are probably more that would be pulled in if I enabled all these sites in NoScript. This is seriously pathetic.
I am becoming gerund, destroyer of verbs.
