Explanation:
A stereo view of
the closest star, this creatively
composited image was constructed from an extensive archive
of pictures taken between March 2004 and
April 2005.
When viewed with
red/blue glasses, the
Sun's disk and
surface features, including
sunspots,
filaments, and
prominences,
stand out in an exaggerated stereo perspective.
The images were recorded through a narrow band
hydrogen-alpha
filter, designed to transmit only light from hydrogen atoms in
the solar atmosphere.
After
combining the solar hydrogen-alpha images,
a 3D star field was added to the final
anaglyphic stereo
view.
