The Sun's Surface in 3D

How smooth is the Sun? The new Swedish 1-m Solar Telescope, deployed in
the Canary Islands only last year, allows imaging of objects less than 100-km
across on the Sun's surface. When pointed toward the Sun's edge, surface
objects now begin to block each other, indicating true three-dimensional
information. Close inspection of the image reveals much vertical information,
including spectacular light-bridges rising nearly 500-km above the floor of
sunspots near the top of the image. Also visible in the above false-color
image are hundreds of bubbling granules, each about 1000-km across,
and small bright regions known as faculas.
