The sun in 3D

Looks pretty cool with 3d glasses. It's really a sphere then.

NASA has just released the first batch of 3-dimensional sun photos taken by the STEREO spacecraft. This image, for instance, reveals three dark holes in the sun's atmosphere:

The "holes" are coronal holes, places where the sun's magnetic field opens up and allows solar wind to escape. Earth is inside a solar wind stream flowing from one of these coronal holes today. 3D imagery allows scientists to peer inside coronal holes and divine their structure, possibly leading to better space weather forecasts.
