Skywatchers at high latitudes could be in for a spectacular treat of northern lights, the aurora borealis, Tuesday and Wednesday: After a relatively quiet stretch, it appears the sun is ramping up its activity.
The sun's surface erupted early Sunday, blasting - tons of plasma (ionized atoms) into space. These atoms are headed toward Earth and could create a stunning light show in the process.
"This eruption is directed right at us and is expected to get here early in the day on Aug. 4th," said Leon Golub of the Harvard-Smithsonian Center for Astrophysics. "It's the first major Earth-directed eruption in quite some time."
