pretty cool huh. you can really see the spiraling dust clouds (well, imagine the spiraling anyway). the brightest point houses the black-hole that is theorised to be at the center of our neat little milky way galaxy, and keeps it all doing what galaxys do (spin spin!). it's bright, coz it's hot , think of it glowing red with heat.
to tell the truth i havn't really had a clue where the center of the galaxy is in the night sky, too bad we can't see it with the naked eye huh. the cosmic dust (thickest around the center of the galaxy) blanks it all out.

Yahoo News is a good source for astronomy mind candy. Here's an example:
Stellar black holes -- the remains of collapsed stars, are common. They typically harbor as much mass as a few suns. And for years, scientists have known there are supermassive black holes in many galaxies; one with the mass of more than three million suns anchors the Milky Way.

dust velocity
The radial velocity of the dust/gas differs with distance from the center...as it approaches the event horizon,{visible edge of the black hole}Phoenix Red wrote:how fast does that dust spin?
it is accelerated to nearly the speed of light.
