Study of stars, galaxies, and cosmology. A great deal of the research record and astronomical data can be found using open sources on the web, including those featured here, the SIMBAD Astronomical Database, astro-ph, and NED, the NASA/IPAD Extragalactic Database, which provides " a multi-wavelength fusion of data for millions of objects outside the Milky Way galaxy." The Astronomy print collection can be found shelved in the Sciences Library.
