New three dimensional vantage point of the sun 'New three dimensional vantage point of the sun'

NASA says it's official: The sun is round.

The U.S. space agency released for the very first time on Sunday (February 6) images that show the complete surface of the Sun.

The 360-degree images were captured by NASA's twin STEREO orbiting space telescopes.

 

Each STEREO telescope -- tuned to trace key aspects of solar activity such as flares, tsunamis and magnetic filaments -- photographs half of the star and beams the images to Earth. Researchers then combine the two views to create a sphere.

'The STEREO probes left Earth on October 2006'

 

NASA has been building toward this moment since Oct. 2006 when the STEREO probes left Earth, split up, and headed for positions on opposite sides of the sun.

NOAA is already using 3D STEREO models to improve weather forecasts for airlines, power companies, and satellite operators. NASA expects the full sun view should improve those forecasts even more.
