POPSTelescope spots monster galactic cluster They theorize that the fact that it's 7.7 billion light years away (as far as they know) meant that it was before the acceleration due to dark energy made it impossible for galactic clusters that large to hold together. It reminded me of a poem by Hughes Mearns. 'Antigonish' As I was going up the stair, I saw a star that wasn’t there. It wasn’t there again today, I wish, that star would stay away. (I thought I'd adjust it to cover Light years, and dark matter.)

POPSExplore Space from Your Computer If you're in need of a quick break from the daily grind, check out this new, free software from Microsoft called WorldWide Telescope. It's a program that allows users to easily scan the universe and look at nebulas, star clusters and other very cool things. I downloaded it quickly and was able to use it immediately. The images are astonishing and it will leave you craving to know more about outer space. I hadn't given much thought to intergalactic travel before seeing this, but I'm now definitely intrigued.

POPSOur busy galaxy
Even our Milky Way galaxy is spinning like a giant Ferris wheel at nearly 140 miles per second. It's also careening at 50 miles per second toward the Great Andromeda galaxy, one of about 30 such structures that create a galactic family astronomers know as the “Local Group,” which, by the way, is falling toward the Virgo supercluster at another 150 miles per second. And if that's not enough, beyond are even more galaxy superclusters as far as the largest telescopes can see. All are rushing away from each other as if hurled from a huge cosmic explosion some 15 billion or 20 billion years ago. Between the clusters glows the faint, ghostly echo of this primordial fireball, through which we speed at more than a million miles per hour. And what about the universe itself? Is it turning about an even larger universe? Is it speeding along in some unknown direction at an even more incredible speed? No one knows for sure, but it's certainly fun to ponder while we wait in yet another motion

POPSGood time to spot the Andromeda Galaxy "The light from that "little cloud" is actually the total accumulation of light from more than 400 billion stars. It is listed as Messier ("M") 31, in Charles Messier's famous catalogue: hazy objects resembling comets, but later proved to be galaxies, nebulae and star clusters. Here is the most distant object that can be seen with the unaided eye. "

POPSColliding Galaxies Make Love, Not War From 02:42 on, the video on stage6.divx.com provides an impression of the aesthetic magnificence of this bi-galactic interaction. The video gains special charm by Pink Floyd's music (Cluster One, Division Bell) which is added to it. Thanks to rj3sp whose clip Dance Of Two Interacting Galaxies reminded me of that video, which is one of my favorites.
