Projected view of filaments feeding the Virgo Cluster.
In the terminology (and numbering scheme) presented in the Nearby Galaxies Catalog and Atlas, these filaments are, at 2 o'clock: Draco Cloud (44); at 3 o'clock: Ursa Major Cloud (12); at 5 o'clock: Leo Cloud (21); at 7 o'clock: Crater Cloud (22); at 9 o'clock: Virgo Southern Extension (11); at 11 o'clock: Virgo-Libra Cloud (41).

What's Up in the Universe?

I am science advisor for the PBS documentary What's Up in the Universe?

Manipulate a data cube of 30,000 galaxies.

A VRML viewer is required to visualize and manipulate this data cube. Viewers for Mac and PC can be downloaded from cortona. For Netscape/Mozilla under UNIX/LINUX try the plug in from freewrl.
