Solar Flare in 3-D
A 3-D image of an active sun shows sunspots and "wonderful active regions in exquisite detail," according to NASA's Solar Dynamics Observatory. (See where you can get 3-D glasses to better appreciate this image.)
A powerful sun storm—associated with the second biggest solar flare of the current 11-year sun cycle—hit Earth last week.
Despite warnings of possible GPS, communications, and power failures, Thursday's sun storm was a softy, scientists say.
