In a far-off galaxy, 12.4 billion light-years from Earth, a ravenous black hole is devouring galactic grub. Its feeding frenzy produces so much energy, it stirs up gas across its entire galaxy.

Data from three of NASA's Great Observatories uncover the most massive galaxy cluster ever detected in the early universe.

Nine NITARP alumni educators, some of their current students, and a student alumna have all returned this year to AAS, paying their own way to attend the international conference.

A new study has found five objects with similar properties to the most luminous and massive stellar system within 10,000 light-years of Earth.

More than 50 teachers, students and astronomy educators from the NASA/IPAC Teacher Archive Research Program (NITARP) will be attending the winter meeting of the American Astronomical Society (AAS).

Astronomers are finding dozens of the fastest stars in our galaxy with the help of images from NASA's Spitzer Space Telescope and Wide-field Infrared Survey Explorer, or WISE.

Euclid, a planned mission to investigate the profound cosmic mysteries of dark matter and dark energy, has passed its preliminary design review. This clears the way for construction to begin. Euclid is a European Space Agency mission with important contributions from NASA, including infrared detectors for one instrument and science and data analysis.

The fantasy creations of the "Star Wars" universe are strikingly similar to real planets in our own Milky Way galaxy. A super Earth in deep freeze? Think ice-planet "Hoth." And that distant world with double sunsets can't help but summon thoughts of sandy "Tatooine."

Version 4.0 of the Montage Image Mosaic Toolkit has been released with a BSD 3-clause license. This is major new release that contains new modules to support processing of data cubes, and a command-line visualization tool.

The Infrared Processing and Analysis Center (IPAC) and the Space Telescope Science Institute (STScI), in coordination with the WFIRST Study Office at GSFC and JPL, are pleased to announce that registration is now open for "Community Astrophysics with WFIRST: Guest Observer and Archival Science" - an international meeting to be held in Pasadena from 29 February through 2 March 2016.

The development of Infrared astronomy over the past fifty years has transformed our view of the Universe. This year we celebrate five decades of IR astronomy at Caltech. In particular, we honor the contributions of Gerry Neugebauer, Keith Matthews, and Tom Soifer to the past, present and future of IR astronomy at Caltech.
