What NASA Is Learning from the Biggest Geomagnetic Storm in 20 Years

One year on, NASA scientists are still making huge discoveries about the largest geomagnetic storm to hit Earth in two decades, the Gannon storm. The findings are helping us better understand and prepare for the ways in which the Sun’s activity can affect us. One year ago today, representatives from NASA and about 30 other […]

Alphabet Soup: NASA’s GOLD Finds Surprising C, X Shapes in Atmosphere

Who knew Earth’s upper atmosphere was like alphabet soup? NASA’s Global-scale Observations of the Limb and Disk (GOLD) mission has revealed unexpected C- and X-shaped formations in an electrified layer of gas high above our heads called the ionosphere.
