Explanation:
Venus glides in front of an
enormous solar disk in these two frames from the
TRACE satellite imaging
of the inner planet's 2004 transit.
Arranged in a "right/left" stereogram, the
frames are intended
to be viewed at a comfortable distance from the
screen with your eyes gently crossed, allowing the images
to merge and produce a pleasing stereo effect.
Shown during the ingress (beginning) phase of the transit,
the silhouetted portion of the planet appears to
float dramatically
in front of the Sun's granulated surface.
Of course, the dense
Cytherian
(Venusian) atmosphere also scatters
and refracts the intense sunlight.
The effect is visible across the portion of the planet
still beyond
the Sun's edge and
viewed against
the blackness of space.
