New! Flash Movie

Technology is changing, and the ESPG is changing with it! The latest internet fad, Macromedia Flash, may be annoying for intro screens, but is a great tool for making web movies! The first in our new series, a movie on the Interstellar Gas and how we on earth can study it, is 1/100 the size of similar QuickTime movies. We will eventually convert all the QuickTime films into Flash, as downloads are incredibly fast and will thus allow our modem-based surfers the opportunity to view movies.

You will need the free Flash player to view this movie -- downloads are quick and easy from (Many browsers are already Flash-enabled, so you may not need to download the player.)
