The Infrared Processing and Analysis Center (IPAC) at Caltech is dedicated to science operations, data archives, and community support for astronomy and solar system science missions, with a historical emphasis on infrared-submillimeter astronomy and exoplanet science.


Spitzer Telescope Honored by Aerospace Society Spitzer Space Telescope Thu, Aug 07, 2014

NASA's Spitzer Space Telescope has received the 2014 AIAA Space Science Award for its ongoing infrared studies of the hidden cosmos. The American Institute of Aeronautics and Astronautics, or AIAA, a society for the field of aerospace engineering, established the award in 1961 for "individuals demonstrating leadership of innovative scientific investigation associated with space science missions."

The Most Precise Measurement of an Alien World's Size Feature14-16_sq Spitzer Space Telescope Wed, Jul 23, 2014

NASA's Kepler and Spitzer space telescopes have made the most precise measurement yet of the size of a planet beyond our solar system.

NEOWISE Spots a Comet That Looked Like an Asteroid Pia18653-640 WISE Wed, Jul 23, 2014

Comet C/2013 UQ4 (Catalina) has been observed by NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft just one day after passing through its closest approach to the sun. The comet glows brightly in infrared wavelengths, with a dust tail streaking more than 62,000 miles (100,000 kilometers) across the sky. Its spectacular activity is driven by the vaporization of ice that has been preserved from the time of planet formation 4.5 billion years ago.

Black Hole Fireworks in Nearby Galaxy Feature14-15_sq Spitzer Space Telescope Wed, Jul 02, 2014

Celebrants this Fourth of July will enjoy the dazzling lights and booming shock waves from the explosions of fireworks. A similarly styled event is taking place in the galaxy Messier 106, as seen by NASA's Spitzer Space Telescope, Chandra X-ray Observatory and the Herschel Space Observatory.

Young Sun’s Violent History Solves Meteorite Mystery Nhsc2014-010_tn Herschel Space Observatory Tue, Jul 01, 2014

Astronomers using ESA’s Herschel space observatory to probe the turbulent beginnings of a Sun-like star have found evidence of mighty stellar winds that could solve a puzzling meteorite mystery in our own back yard.

Organic conundrum in Large Magellanic Cloud Partner88_sq Spitzer Space Telescope Mon, Jun 23, 2014

A group of organic chemicals that are considered carcinogens and pollutants today on Earth, but are also thought to be the building blocks for the origins of life, may hold clues to how carbon-rich chemicals created in stars are processed and recycled in space.

Spitzer Spies an Odd, Tiny Asteroid Feature14-14_sq Spitzer Space Telescope Thu, Jun 19, 2014

Astronomers using NASA's Spitzer Space Telescope have measured the size of an asteroid candidate for NASA's Asteroid Redirect Mission (ARM), a proposed spacecraft concept to capture either a small asteroid, or a boulder from an asteroid. The near-Earth asteroid, called 2011 MD, was found to be roughly 20 feet (6 meters) in size, and its structure appears to contain a lot of empty space, perhaps resembling a pile of rubble. Spitzer's infrared vision was key to sizing up the asteroid.

New Molecules Around Old Stars Nhsc2014-009_tn Herschel Space Observatory Tue, Jun 17, 2014

Astronomers have discovered that a molecule vital for creating water exists in the burning embers of dying Sun-like stars. When low- to middleweight stars like our Sun approach the end of their lives, they eventually become dense, white dwarf stars. In doing so, they cast off their outer layers of dust and gas into space, creating a kaleidoscope of intricate patterns known as planetary nebulas.

Wide-field InfraRed Surveys: Science and Techniques Announcement Fri, Apr 25, 2014

This conference is intended for scientists to consider recent progress especially from NASA missions such as Spitzer, Kepler, Hubble and WISE, as it affects the design of the next generation of space-based infrared surveys, including the Decadal Survey's top priority, a wide-field infrared survey telescope (WFIRST).

KOA Releases ESI Data Science Release Thu, Jul 31, 2014

The Keck Observatory Archive (KOA) has released to the public, data from the Echellette Spectrograph and Imager (ESI) instrument. 780 nights of data have been released, consisting of 21,988 science files and 27,935 calibration files. KOA has also released to PIs, 973 nights of data from the the now decommissioned Near Infrared Camera (NIRC), comprising 263,238 files with a data volume of 276 GB. These data will start to become public in July 2015.

Spring 2015 IPAC Visiting Graduate Student Fellowship Announcement Mon, Jun 09, 2014

The Infrared Processing and Analysis Center at Caltech announces the availability of six-month graduate student fellowships beginning in the Spring of 2015. 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 2015.

KOA Releases DEIMOS Data Announcement Wed, Apr 02, 2014

The Keck Observatory Archive has released to the public 628 nights of data from the DEIMOS instrument. The released data include 27,409 science files and 56,514 calibration files.
