    Discover the cosmos! [1] Each day a different image or photograph of our
 fascinating universe is featured, along with a brief explanation written by a
                           professional astronomer.

Explanation: Taken on the same night, from the same place, with the same
telescope and camera, these postcards from our Solar System [6]  are shown at
the same scale to provide an interesting [7]  comparison of apparent sizes.
Spanning about [8] half a degree in planet Earth's sky, the Moon is a stitched
mosaic of six images. The others are the result of digitally stacked frames or
simple single exposures, with the real distances [9]  to the objects indicated
along the bottom of each insert. Most of the Solar System's planets with their
brighter moons, and Pluto were captured during the telescopic expedition, but
elusive Mercury was missed because of clouds near the horizon. The
International Space Station [10] was successfully hunted, though. The night
was July 21st. Telescope and camera were located at the Centro Astronomico de
Tiedra [11] Observatory in Spain.
