WHISPERS FROM THE COSMOS
High in a dry plain at Hat Creek in northern California sits the Berkeley-Illinois-Maryland Association's (BIMA) radiosynthesis array.

The BIMA array's many receiving dishes act as a single telescope, searching the heavens for clues to such questions as:
Is space really empty?
What lies between the stars?
Can molecules, including those we're made out of, form in space?
How are stars born?
What determines the shapes of galaxies?
Buried in the radio signals that the BIMA array collects from space are the answers to these intriguing questions. First, though,
scientists must turn the mountains of data produced by the telescope into images, especially radio maps, that yield insight.
Important advances in computing technologies and high speed telecommunications are now enabling them to do this much more quickly.
As a result, the pace of discovery from the BIMA array and other radiotelescopes promises to quicken by leaps and bounds.
You might like to take a two-minute video tour of this exhibit's contents. However, the Quicktime movie is
rather large (12.1 MB!), so be patient when downloading. It'll take a few
minutes. (Further information on downloading movies can be obtained from the
and Navigation Tips.)
Alternatively, you can get a good idea of what the video shows and tells by looking at the video script and thumbnails.
The script also offers links into the exhibit itself.
