NOAA’s New Satellite Reveals Earth in Stunning Detail
NOAA’s new weather satellite sent back its first images and the Earth has never looked sharper. 22,300 miles above the Earth sounds like a long way, but from that distance the GOES-16 satellite is able to capture high-resolution images that are allowing us to see our planet in clearer detail than we ever have before. Launched in November 2016, the new satellite is the first of four new satellites that will transmit images at a higher-resolution than previously possible. The resulting pictures are pretty to look at but that’s not the point. These images could save lives.

On a recent stormy day, choppy waves crashed into the Scripps pier. Scenes like this are probably what most people picture when they think of waves. But surface waves aren’t the only kind. Scripps Institution of Oceanography researcher Peter Franks is interested in waves beneath the surface — internal waves. “These are gigantic waves,” he said. “If you could surf them, you’d surf for days — very, very, very slowly.” Franks studies how phytoplankton interact with internal waves. Phytoplankton are the tiny single-celled organisms that form the crucial base of the ocean’s food chain. Internal waves can play a role in accumulations of plankton such as red tides, which can sometimes be toxic. But Franks said piecing together exactly how that happens isn’t easy.
