Named the Hubble Source Catalog (HSC), it now allows astronomers to perform a computer search for characteristics of roughly 100 million small sources ranging from distant galaxies to compact star clusters to individual stars, receiving information within seconds or minutes.
Hubble has amassed a rich legacy of images and other scientific data over its 25 years of exploring the universe. All of the images are stored in the computer-based Barbara A. Mikulski Archive for Space Telescopes (MAST), which astronomers use for their research. The archive is bursting with more than a million images, which contain roughly 100 million small sources ranging from distant galaxies to compact star clusters to individual stars. For astronomers, however, a major challenge is the difficulty involved with sifting through the archival gold mine to collect the data they want to analyze. The Hubble Source Catalog now allows astronomers to readily perform a computer search for characteristics of these sources.
It lists all of the sources, and includes both a summary and compilation of the measurements for each object. The measurements include information about the brightness of sources, as well as a source’s color and shape.
The catalog brings together observations from the three primary cameras that have served Hubble since 1993: the Wide Field Planetary Camera 2, Advanced Camera for Surveys, and Wide Field Camera 3. The three cameras combined make observations spanning a wide swath of the spectrum, from ultraviolet to visible and near-infrared light. The catalog lists all of the sources, and includes both a summary and compilation of the measurements for each object. The measurements include information about the brightness of sources, as well as a source's color and shape. Astronomers released the first version of the catalog on Feb. 25.

Good news on my doorstep, thanks for the thread, well deserving of a bump-de-bump.
This is excellent news for anyone who hates digging through massive amounts of data. I'm willing to bet that entails everybody. I know ATS will put it to good use and I can't wait to start digging. I had some trouble getting it to work, but it seems to be up and running.
