Apr 15, 2014 – UPDATE: NEOWISE Is Out of Safe Mode - the NEOWISE Flight System Exited Safe Mode on April 9th
The NEOWISE mission was commanded into safe mode on April 3 following a flight software error.  The software failed to issue commands successfully to reaction wheels; this was resolved by resetting the flight computer via ground command.  The flight system is now performing well in safe mode, the telescope temperature remains stable at around 73 K (about -328 degrees Fahrenheit), and the science instrument has been powered off.  The vehicle will remain in safe mode while the team runs diagnostics to understand the cause of the error. Visit

Mar. 26, 2014 – The Search for Seeds of Black Holes
How do you grow a supermassive black hole that is a million to a billion times the mass of our sun? Astronomers do not know the answer, but a new study using data from WISE has turned up what might be the cosmic seeds from which a black hole will sprout. The results are helping scientists piece together the evolution of supermassive black holes. Visit

Nov 13, 2013 – AllWISE Data Release
The 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. A quick guide to the AllWISE data release, data access instructions and supporting documentation is available at IPAC. Visit

Mar. 7, 2014 – NASA's WISE Survey Finds Thousands of New Stars, But No 'Planet X'

After searching hundreds of millions of objects across our sky, NASA's Wide-Field Infrared Survey Explorer (WISE) has turned up no evidence of the hypothesized celestial body in our solar system commonly dubbed "Planet X."

Size & Scale of the Universe 
The Universe is very, very big. One cannot reasonably create a scale model of the Universe that includes all of its components—from people to superclusters—and simultaneously scales their distances and sizes. This activity attempts to overcome that difficulty by examining the Universe at different realms.
