... These Frontier Fields will combine the power of HST with the natural gravitational telescopes of high-magnification clusters of galaxies. ... We are soliciting gravitational lensing maps for the last four Hubble Frontier Fields clusters (MACSJ0717.5+3745, MACSJ1149.5+2223, AbellS1063, and Abell 370) based upon the exceptionally deep HST FF imaging and other new ancillary data. ... For the full set of proposal instructions and requirements, see the FY16 Frontier Fields Lensing Map Call for Proposals....

As noted earlier Kristian Birkeland, reporting in 1903 on his expeditions to the auroral zone, proposed that magnetic disturbances accompanying the aurora were caused by large electric currents flowing down the length of auroral formations. ... Some scientists disagreed with Birkeland and claimed the electrojets did not connect to space but instead their entire circuit lay inside the ionosphere, like that of other ionospheric currents known at the time, believed to be caused by atmospheric tides. ...

The Arecibo Observatory-- at nearly 1000' across--is the world's largest radio and radar telescope. Located in northwestern Puerto Rico, the original facility was built 40+ years ago, but it underwent major upgrades in the 1970s and in 1997-99. ... The observatory operates with a staff of about 125 and a yearly budget of about $12M, 5/6ths of which comes from NSF-astronomy and most of the remainder from NSF-atmospheres. ... This will extend the telescope's life by 20-30 years. ...
