Volcano Euboea Fluctus On Io
Explanation:
Jupiter's moon
Io is turning out to be our
Solar System's geologic powerhouse. The churning moon
was photographed again just recently on June 27th and again shows signs of violent
activity.
Shown above are photographs
of the volcano Euboea Fluctus taken at different times. The black and white photograph
on the upper left was taken by the
Voyager 1 spacecraft
when it flew by in 1979, the upper right and lower left photographs were taken in
1996 by the
Galileo spacecraft, while the lower right photograph
is a color image taken by Voyager 2, also in 1979. The upper right Galileo picture
has been artifically changed to simulate the color sensitivity of the
Voyager 2 mission. The marked difference in the two
images is highlighted by new red and yellow deposits. These markings may indicate
that Euboea Fluctus erupts in an unusual fashion, possibly caused by an obstruction
near the volcanic vent.
