March 13, 2015: 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 .
