Cassiopeia A: Chandra Discovers Relativistic Pinball Machine, originally uploaded by Smithsonian Institution.
Happy New Year my friends.
This photograph of Cassiopeia A is from "NASA's Chandra X-ray Observatory, which was launched and deployed by Space Shuttle Comlumbia on July 23, 1999."
So it's a visually spectacular introduction to the International Year of Astronomy.
Closer to home, I commend the website and blog of the Sydney Observatory.
For old school stuff, I've got an especially soft spot for the Sydney Observatory's Historic Letters Blog.
NASA also has a pretty cool site featuring the IYA here.
