Imagine you want to measure the size of a room, but it's completely dark. If you shout, you can tell if the space you're in is relatively big or small, depending on how long it takes to hear the echo after it bounces off the wall.
ESA's Herschel mission releases today a series of unprecedented maps of star-forming hubs in the plane of our Milky Way galaxy. This is accompanied by a set of catalogues listing hundreds of thousands of compact sources that span all phases leading to the birth of stars in our Galaxy.
A nebula known as "the Spider" glows fluorescent green in an infrared image from NASA's Spitzer Space Telescope and the Two Micron All Sky Survey (2MASS). The Spider, officially named IC 417, lies near a much smaller object called NGC 1931, not pictured in the image. Together, the two are called "The Spider and the Fly" nebulae. Nebulae are clouds of interstellar gas and dust where stars can form.
BBC recently released Horizon's new episode, "The Mystery of Dark Energy". Some of the footage from this episode was shot during the Euclid Consortium meeting in Lausanne, Switzerland in June 2015.
Observations from NASA's Spitzer Space Telescope have led to the first temperature map of a super-Earth planet -- a rocky planet nearly two times as big as ours. The map reveals extreme temperature swings from one side of the planet to the other, and hints that a possible reason for this is the presence of lava flows.
How do some gas giant planets end up so feverishly close to their stars? NASA's Spitzer Space Telescope finds new clues.
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.
The Infrared Processing and Analysis Center at Caltech announces the availability of six-month graduate student fellowships beginning in the Spring of 2016. 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 2016.
NASA is seeking input from the science community that will culminate in a decision to support studies of three or four large missions to prepare for the next Decadal Survey in Astrophysics. A white paper released by NASA's Astrophysics Division lists four candidate missions, including a Far-Infrared Surveyor mission.
The fifteenth annual Greater IPAC Science Symposium will be held on Thursday and Friday, April 23 and 24, 2015. The Science Symposium is a forum for all staff members of IPAC, the Spitzer Science Center (SSC), the NASA Herschel Science Center (NHSC) and the NASA Exoplanet Science Institute (NExScI) to present, discuss and learn about the diverse research that is being carried out at the Greater IPAC.
