A team of researchers has compiled a special catalog to help astronomers figure out the true distances to tens of thousands of galaxies beyond our own Milky Way. The catalog, called NED-D, is a critical resource, not only for studying these galaxies, but also for determining the distances to billions of other galaxies strewn throughout the universe. NED-D is part of the NASA/IPAC Extragalactic Database (NED), an online repository containing information on more than 100 million galaxies.
NASA's NEOWISE mission has recently discovered some celestial objects traveling through our neighborhood, including one on the blurry line between asteroid and comet. Another--definitely a comet--might be seen with binoculars through next week.
In the "Star Wars" universe, ice, ocean and desert planets burst from the darkness as your ship drops out of light speed. But these worlds might be more than just science fiction.
ENSCI will be at the IPAC Booth at the 229th AAS meeting on January 3-7, 2017, in Grapevine, Texas.
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.
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.
