A planet and a star are having a tumultuous romance that can be detected from 370 light-years away. NASA's Spitzer Space Telescope has detected unusual pulsations in the outer shell of a star called HAT-P-2. Scientists' best guess is that a closely orbiting planet, called HAT-P-2b, causes these vibrations each time it gets close to the star in its orbit.
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 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 As of Oct 1 3,480 nights of LRIS data have been archived, and 3,294 nights are public.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.
