The Cassini probe of the US Space Agency (NASA) has recorded the image of Saturn's Titan moon. The image shows a blue mist surrounding the moon's orange surface. Scientists believe that the fog is green because the fog particles are smaller than the lower atmosphere molecules.

The WISE space telescope shows the latest image of the Barnard nebula 3. This nebula is red in the center of the constellation in the outer blue region. The middle of the nebula is a bright star forming.

The picture taken from NASA's No. 1 Earth observation satellite shows that volcanic activity from the Red Sea bottom made an appearance on this small island.

A Soyuz rocket is available on the launch pad at Baikonur Space Center in Kazakhstan on December 21. In winter, the center of the universe is always covered by white snow because the heat is always below 0 degrees C.
