Herschel has produced an intricate view of the remains of a star that died in a stellar explosion a millennium ago. It has provided further proof that the interstellar dust which lies throughout our Galaxy is created when massive stars reach the end of their lives.

Astronomers trace water in Jupiter's intermediate atmospheric layer back to the famous Shoemaker-Levy 9 comet impact of 19 years ago.

NASA's Kepler mission has discovered two new planetary systems that include three super-Earth-size planets in the "habitable zone," the range of distance from a star where the surface temperature of an orbiting planet might be suitable for liquid water.

Busy-bee galaxy seen churning out stars when our universe was just a baby.

An infrared sensor that could improve NASA's future detecting and tracking of asteroids and comets has passed a critical design test.

Planck's all sky maps showing the oldest light in our universe, as well as the calculated distribution of mass of the universe, are now available in a format suitable for use in planetarium systems and other 3D software.

ESA, NASA, the Planck Collaboration, and IRSA announce the first release of all sky temperature maps, foreground component maps and cosmology results from the Planck mission. The NASA Planck Archive is hosted at IRSA within IPAC.

Information about NASA's 2009 Decadal Process.

A number of IPAC projects, teams and individuals were honored today with NASA Achievement Awards. These recognitions reflect the dedication and creativity of these individuals and teams as well as the support and contributions by many others at IPAC that make each success possible.

This conference aims to explore the formation and evolution of galaxies using mostly gas tracers. Infrared and submillimeter observations gauge not only the quantity and distribution of gas in galaxies, but also the thermal and dynamical state of its various phases. Star formation and feedback involve physics that can be constrained with long wavelength observations: photoelectric heating, UV excitation, turbulence, cosmic rays, shock waves, atomic and molecular line emission, and thermal emission from dust. The conference will begin with what we know about the physical conditions of gas in the nearby universe out to z = 1, and then push outwards to earlier epochs when galaxies were forming most of their stars.

The National Reconnaissance Observatory (NRO) has recently transferred to NASA optical hardware the equivalent of two Hubble-class optical telescopes. This Notice of Intent is to alert the astrophysical community that the Astrophysics Division in the Science Mission Directorate at NASA HQ intends to release a “Dear Colleague” letter to solicit applications from interested individuals for the formation of a study group for the possible scientific use(s) of the ex- NRO telescope assets for advancing the science priorities of the 2010 Decadal Survey.

The Infrared Processing and Analysis Center at Caltech announces the availability of six-month graduate student fellowships beginning in the Spring of 2013. The program is designed to allow students from other institutions to visit IPAC-Caltech and perform astronomical research in close association with an IPAC staff member during Spring 2013.
