The Birth of Monsters: VISTA Pinpoints Earliest Giant Galaxies Eso1545b-sq Spitzer Space Telescope Wed, Nov 18, 2015

ESO’s VISTA survey telescope has spied a horde of previously hidden massive galaxies that existed when the Universe was in its infancy. By discovering and studying more of these galaxies than ever before, astronomers have, for the first time, found out exactly when such monster galaxies first appeared.

Community Astrophysics with WFIRST: Guest Observer and Archival Science Wfirstpicture Euclid Mon, Nov 16, 2015

The Wide Field Infrared Survey Telescope (WFIRST) is a NASA mission currently under study for the next decade whose primary objectives are to study the nature of dark energy, via gravitational lensing, supernovae and baryon acoustic oscillations, and search for and characterize exoplanets, via microlensing and coronagraphy. This international meeting, "Community Astrophysics with WFIRST: Guest Observer and Archival Science", to be held in Pasadena from 29 Feb. through 2 March 2016, will focus on the GO and GI components of the WFIRST mission, bringing together experts in the community to discuss groundbreaking science that can be done with the GO and archival opportunities of WFIRST. Due to the synergy between WFIRST and Euclid, this meeting is of great interest to the Euclid community.

Whopping Galaxy Cluster Spotted with Help of NASA Telescopes Feature15-11_sq Spitzer Space Telescope Tue, Nov 03, 2015

Astronomers have discovered a giant gathering of galaxies in a very remote part of the universe, thanks to NASA's Spitzer Space Telescope and Wide-field Infrared Survey Explorer (WISE). The galaxy cluster, located 8.5 billion light-years away, is the most massive structure yet found at such great distances.

NEOCam one of 5 mission proposals picked by NASA for further study Neocam_wide NEOCam Wed, Sep 30, 2015

NEOCam is one of 5 mission proposals picked by NASA for further study. NEOCam is an infrared asteroid-hunting telescope, which would discover 2/3 of near-Earth objects larger than 140m.

Too Big for its Boots: Black Hole is 30 Times Expected Size Partner094_sq Spitzer Space Telescope Thu, Sep 24, 2015

The central supermassive black hole of a recently discovered galaxy is far larger than should be possible, according to current theories of galactic evolution.

Funky Light Signal From Colliding Black Holes Explained Glx2004-01r_img01_tn GALEX Wed, Sep 16, 2015

Entangled by gravity and destined to merge, two candidate black holes in a distant galaxy appear to be locked in an intricate dance. Researchers using data from NASA's Galaxy Evolution Explorer (GALEX) and NASA's Hubble Space Telescope have come up with the most compelling confirmation yet for the existence of these merging black holes and have found new details about their odd, cyclical light signal.

NASA Telescopes Find Galaxy Cluster with Vibrant Heart Ssc2015-03_sq Spitzer Space Telescope Thu, Sep 10, 2015

Astronomers have discovered a rare beast of a galaxy cluster whose heart is bursting with new stars. The unexpected find, made with the help of NASA's Spitzer and Hubble space telescopes, suggests that behemoth galaxies at the cores of these massive clusters can grow significantly by feeding off gas stolen from another galaxy
