Astronomers from around the world have submitted more than 4,500 images of Comet Hale-Bopp to NASA Web sites, where Internet users can see them and enjoy the celestial show. The Comet Hale-Bopp Home Page at NASA's Jet Propulsion Laboratory (Pasadena, CA) contains more than 3,200 images, including one obtained by a California astronomer the night after the comet was discovered in July 1995. The Near-Live Comet Watching System at NASA Headquarters (Washington, DC) contains more than 1,300 images.
Astronomers from Australia, Asia, Europe and the Americas have submitted images, which have been captured by everything from professional observatory equipment to the backyard gear of an amateur astronomer. The archives include photographs of the comet over San Francisco; Dublin, Ireland; and Genoa, Italy.
Positive Research will address the needs of ultra-fast laser developersPositive Light (Los Gatos, CA) and Chris Barty of San Diego, CA, have founded a new company, Positive Research, to address the needs of ultrafast-laser users and developers. The company will specifically target market areas where no "off-the-shelf" commercial product is available, such as one-of-a-kind lasers, amplifiers, components, and diagnostics.Examples of such products include 20-fs single-shot autocorrelators, sub-10-fs interferometric autocorrelators, and 20-fs amplifier kits. The company has shipped its first product, a high-order phase-compensated pulse expander for sub-20-fs pulse amplification.
