SWOT Satellite Catches Coastal Flooding During California Storms

4 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) This image shows SWOT satellite data for water surface height in part of Mendocino County, Northern California, on Jan. 15, before several atmospheric rivers arrived, and on Feb. 4, after the first storms. Light blue and green indicate the highest water levels relative to mean sea level. (Inland water heights include the underlying ground elevation.) NASA/JPL-Caltech Operated by NASA and the French space agency, the Surface Water and Ocean Topography mission provides a new view of water on land,…

What’s Made in a Thunderstorm and Faster Than Lightning? Gamma Rays!

3 min read What’s Made in a Thunderstorm and Faster Than Lightning? Gamma Rays! A flash of lightning. A roll of thunder. These are normal stormy sights and sounds. But sometimes, up above the clouds, stranger things happen. Our Fermi Gamma-ray Space Telescope has spotted bursts of gamma rays – some of the highest-energy forms of light in the universe – coming from thunderstorms. Gamma rays are usually found coming from objects with crazy extreme physics like neutron stars and black holes. So why is Fermi seeing them come from thunderstorms? About a thousand times a…
