On May 11, 2024, the day-night band of VIIRS (Visible Infrared Imaging Radiometer Suite) on the Suomi NPP satellite spotted the aurora borealis over the United States during the strongest geomagnetic storm in over two decades. That same night, observers on the ground captured spectacular photographs of the dazzling light. The following photos represent just a handful of those shot by citizen scientists as part of NASA’s Aurorasaurus project, which tracks aurora sightings around the planet. Photo by Gunjan Sinha, acquired on May 11, 2024, from near Saskatoon in Saskatchewan, Canada. P ..read more

Eclipse Challenge: Clouds and Our Solar-Powered Earth

Energy from the Sun warms our planet, and changes in sunlight can also cause changes in temperature, clouds, and wind. Clouds are ever changing and give you clues and information on what is happening in the atmosphere. Clouds can tell you if air is moving vertically (or upward) when you see cumulus type clouds growing in the distance. Clouds can also tell you which direction the wind is blowing when you see clouds move at different levels in the atmosphere. They can even tell you how much moisture or water vapor is available just by the presence of clouds, especially by the presence of high ci ..read more
