Six ‘sub-Neptune’ exoplanets in rhythmic orbits around their star
01.16.24 - TESS Researchers Discover Six-Planet System Using New Algorithms
An international group of scientists have recently uncovered a remarkable system of six exoplanets from data collected by NASA’s Transiting Exoplanet Survey Satellite (TESS). Their years of planetary detective work—which began with light curve processing on the Pleiades supercomputer at the NASA Advanced Supercomputing (NAS) facility—was detailed in a paper published in Nature.
GEOS-Exp 4km model snowfall forecast with 30-hour snowfall total
01.04.24 - GEOS Model Outputs for Early Season Snowfall in the Northeast US
Model outputs from GEOS-FP 12-kilometer (km) and GEOS-Exp 4-km depict an early season snowfall in the mid-Atlantic and northeastern United States on December 11, 2023. GEOS models run at the NASA Center for Climate Simulation (NCCS).
