Let's Explore the Ocean [infographic]

James Cameron's recent journey to the deepest part of the Pacific ocean opened the door for future exploration of the sea floor. But despite covering 72 percent of Earth and supplying more than 70 percent of the world's oxygen, there's still a lot we don't know about our planet's life support system.

Tornadoes on the Sun

Last week, NASA's Solar Dynamics Observatory satellite captured this stunning video of magnetically captured plasma moving like a tornado across the sun's surface.

The sun tornado video shows swirling fountains of plasma creeping across the surface of the sun during a 30-hour period between Feb. 7 and 8. But unlike tornadoes on Earth, which are wind-driven phenomena, the sun's plasma tornadoes are shaped by the powerful magnetic field of our star. A solar physicist at NASA said the tornado might be as large as the Earth itself and have gusts up to 300,000 miles per hour.
