   Explanation: Mars looks sharp in these two rooftop telescope views
   captured in late November from Singapore, planet Earth. At the time,
   [5]Mars was about 82 million kilometers from Singapore and approaching
   its opposition, opposite the Sun in planet Earth's sky on December 8.
   [6]Olympus Mons, largest of the volcanoes in the Tharsis Montes region
   (and largest known volcano in the Solar System), is near Mars' western
   limb. In both the images it's the whitish donut-shape at the upper
   right. The dark area visible near center is the [7]Terra Sirenum region
   while the long dark peninsula closest to the planet's eastern limb is
   Sinus Gomer. Near its tip is Gale crater, the Curiosity rover's
   [8]landing site in 2012. Above Sinus Gomer, white spots are other
   volcanoes in the [9]Elysium region. At top of the planet is the
   [10]north polar cap covered with ice and clouds. Taken about two days
   apart, these images of the same [11]martian hemisphere form a stereo
   pair. Look at the center of the frame and cross your eyes until the
   separate images come together to see the Red Planet in 3D.
