Crackling with flares for several days, Sunspot AR2422, blew off its strongest to date on Sept. 28th, 2015. The M7-scale event “ionized the top of Earth’s atmosphere,” according to Spaceweather.com, triggering a low frequency radio black out over South America and the Atlantic Ocean.

Flowing Water on Mars: The Discovery in Pictures
Planetary scientists have determined that recurring slope lineae flowing downhill on Mars formed by the action of contemporary liquid water. See the discovery…Read More » in this gallery. HERE:These dark, narrow, 100 meter-long streaks (called recurring slope lineae) are flowing downhill on Mars, and are inferred to have been formed by contemporary flowing water. Recently, […]
Salty Water Flows on Mars Today, Boosting Odds for Life
Dark narrow streaks called recurring slope lineae (RSL) emanate from the walls of Mars’ Garni crater in this image by NASA’s Mars Reconnaissance Orbiter. These RSL are up to a few hundred meters in length. They are thought to be formed by the flow of salty liquid water. Credit: NASA/JPL/University of Arizona Liquid water flows on […]
