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.

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.

Herschel Sees Budding Stars and a Giant, Strange Ring Nhsc2014-008_rec Herschel Space Observatory Thu, Jun 12, 2014

The Herschel Space Observatory has uncovered a weird ring of dusty material while obtaining one of the sharpest scans to date of a huge cloud of gas and dust, called NGC 7538. The observations have revealed numerous clumps of material, a baker's dozen of which may evolve into the most powerful kinds of stars in the universe.

Catching a 'Wave' of Galaxies Ending the Dark Ages Feature14-13_sq Spitzer Space Telescope Thu, Jun 12, 2014

Through a project dubbed SURFS UP, NASA's Spitzer Space Telescope and Hubble Space Telescope are catching sight of a "wave" of galaxies that emerged in the early universe. Starlight from these primordial galaxies is reckoned to have cleared a fog of hydrogen gas that shrouded the cosmos during a mysterious period known as the Dark Ages.

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 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. Another 665 nights of data will be released as their propriety period expires. Altogether, the DEIMOS total includes 38,308 science files and 71,881 calibration files (10.2 TB total)

AllWISE DATA RELEASE Announcement Wed, Nov 13, 2013

The Wide-field Infrared Survey Explorer (WISE) and the Infrared Processing and Analysis Center (IPAC) announce the AllWISE Data Release. The AllWISE program combines data from WISE cryogenic and NEOWISE post-cryogenic survey phases, to form the most comprehensive view of the mid-infrared sky currently available.

From IRAS to Spitzer and Beyond: 30 years of Space-Based Infrared Astronomy Irhistory_rec Feature Wed, Nov 13, 2013

2013 is a significant year in infrared astronomy -- it marks the 30th anniversary of the launch of IRAS, the Infrared Astronomical Satellite, which revolutionized our view of the infrared cosmos, increasing the number of known infrared sources by about 70%. This talk will review some of the major discoveries from some of the many important infrared astronomy missions.
