Take a virtual tour of the Sun with NASA's 3D Sun app

As the sun reawakens from an anomalously quiet period, keep track of solar flares, sunspots, and coronal mass ejections with a new iPhone app that puts the real-time status of the sun in your hand.

The 3D Sun app is a free app from NASA that allows you to explore the sun in 3D. You can fly around the sun, zoom in on active regions, and monitor solar activity. The app is powered by data from NASA's STEREO satellites, which orbit the sun millions of miles away. (Nasa)
