In a first-of-its-kind collaboration, NASA's Spitzer and Swift space telescopes joined forces to observe a microlensing event, when a distant star brightens due to the gravitational field of at least one foreground cosmic object.
The Euclid/WFIRST Spitzer Legacy Survey proposal has been selected for observations in Spitzer GO Cycle 13. The PI is Dr. Peter Capak from IPAC, Caltech, leading an international team of 51 Co-Is. This ambitious program has been awarded 5286 hours of Spitzer Legacy Science Time, the most time awarded in this cycle, and a substantial fraction of the total available time in the remainder of currently planned mission lifetime for Spitzer. This program will observe 20 square degrees to 2h per pointing split between the Chandra Deep Field South (CDFS) and the North Ecliptic Pole (NEP). This will achieve 5sigma depths of 24.6 AB mag. It will enable the scientific research on reionization in the Universe, stellar mass from 3<z<10 and luminous quasars.
Life exists in a myriad of wondrous forms, but if you break any organism down to its most basic parts, it's all the same stuff: carbon atoms connected to hydrogen, oxygen, nitrogen and other elements. But how these fundamental substances are created in space has been a longstanding mystery.
The Euclid NASA Science Center (ENSCI) has released an Estimator for Astrophysical Background at L2. This provides an important tool to Euclid scientists for survey optimization.
In the ongoing hunt for the universe's earliest galaxies, NASA's Spitzer Space Telescope has wrapped up its observations for the Frontier Fields project. This ambitious project has combined the power of all three of NASA's Great Observatories -- Spitzer, the Hubble Space Telescope and the Chandra X-ray Observatory -- to delve as far back in time and space as current technology can allow.
To most of us, our home galaxy, the Milky Way, seems like mind-boggling, never-ending space. But what does the Milky Way actually look like? How quickly is the Milky Way giving birth to new stars? In their efforts to answer these complex questions, scientists are figuring out new ways to break down the vast amounts of data they collect.
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.
The Keck Observatory Archive (KOA) has released raw images and spectra from the Low Resolution Imaging Spectrometer (LRIS). As of Oct 1 3,480 nights of LRIS data have been archived, and 3,294 nights are public. These data go back as far as 1994.
