Visualization of gravitational waves emitted by two black holes as they spiral together and merge
04.18.16 – NASA's Fermi Telescope Poised to Pin Down Gravitational Wave Sources
A fascinating video developed by NASA Advanced Supercomputing (NAS) Division visualization experts shows gravitational waves emitted by two black holes as they spiral together and merge. Goddard Space Flight Center scientists used the NAS Pleiades supercomputer to simulate the first-ever detection of gravitational waves, announced on February 11 by the Laser Interferometer Gravitational-Wave Observatory (LIGO).

02.17.16 - Improving Global Model Precipitation Patterns by Downscaling
The inability of global climate models to match the timing or placement of short-term or regional precipation patterns such as the West African monsoon may be alleviated by "downscaling" to use smaller scale climate models with increased area resolution, NASA Goddard Institute for Space Studies research shows.
