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.


Citizen Scientists Lead Astronomers to Mystery Objects in Space Feature15-01_sq Spitzer Space Telescope Tue, Jan 27, 2015

"Hmm, what's that?" Simply by asking the question, volunteers have led researchers to illuminate a little-known stage of massive star formation.

NEOWISE: A Yearlong Look at the Sky Pia19101-800x600 WISE Thu, Jan 15, 2015

NASA's Near-Earth Object Wide-field Survey Explorer (NEOWISE) spacecraft discovered and characterized 40 near-Earth objects (NEOs) in the first year after the mission was re-started in December 2013. Eight of the discoveries have been classified as potentially hazardous asteroids (PHAs), based on their size and how close their orbits could come to Earth's orbit.

Discovering Our Universe from the Classroom: Teacher Research Program Brings NASA Research to Schools Across America Feature14-23_sq Spitzer Space Telescope Tue, Jan 06, 2015

How many high school teachers and kids can say that they have presented their astronomy reach alongside professional astronomers at an international conference? These folks can.

NASA’s Kepler Marks 1,000th Exoplanet Discovery, Uncovers More Small Worlds in Habitable Zones Kepler_hall_of_fame_jan2015_profile-full Kepler Tue, Jan 06, 2015

How many stars like our sun host planets like our Earth? NASA’s Kepler Space Telescope continuously monitored more than 150,000 stars beyond our solar system, and to date has offered scientists an assortment of more than 4,000 candidate planets for further study -- the 1,000th of which was recently verified.

Horsehead of a Different Color Feature14-23_sq Spitzer Space Telescope Fri, Dec 19, 2014

Sometimes a horse of a different color hardly seems to be a horse at all, as, for example, in this newly released image from NASA's Spitzer Space Telescope. The famous Horsehead nebula makes a ghostly appearance on the far right side of the image, but is almost unrecognizable in this infrared view.

Herschel’s view of the early Universe reveals galaxy cluster fireworks Nhsc2014-014 Herschel Space Observatory Thu, Dec 18, 2014

Astronomers using ESA’s Herschel space observatory have found, for the first time, fireworks of star birth within galaxies at the dense core of a massive early Universe galaxy cluster. This frenzy of star formation reveals the young lives of now “red and dead” elliptical galaxies and gives new clues to the evolution of some of the largest structures in the Universe.
