HubbleSite Hubble Source Catalog: One-Stop Shopping for Astronomers

Space Telescope Science



Astronomers at the Space Telescope Science Institute and the Johns Hopkins University, both in Baltimore, Maryland, have created a new master catalog of astronomical objects called the Hubble Source Catalog. The catalog provides one-stop shopping for measurements of objects observed with NASA's Hubble Space Telescope.

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 perform a computer search for characteristics of these sources, receiving information within seconds or minutes.

Join Hubble scientists during a live Hubble Hangout discussion about the Hubble Source Catalog at 3pm (EDT) on Thurs., March 19 to learn more. Visit: http://hbbl.us/Fne .
