  first wonder of the world - Earth colors

Image: We are the first generation to see our planet from outside and in its entirety. The first image of the Earth was taken by Apollo 8 in December 1968 first mission to have carried men beyond Earth orbit. Image Credit: NASA/NOAA/GSFC/Suomi NPP/VIIRS/Norman Kuring

  Wonder of the World - Saturn's rings

Image: The rings of Saturn have complex resonances with some satellites. The satellites 'shepherds' (Atlas, Prometheus and Pandora), roll the edge of the rings and are indispensable for the stability of these. The overall system is very fragile as this picture shows.

  Wonder of the world - the geysers of Enceladus

Image: Enceladus, moon of Saturn, has despite its small size of 500 kilometers in diameter, intense geological activity.

  Wonder of the World - Olympus Mons

Image: Olympus Mons is the largest volcano in the solar system, it sits on a vast plateau of 22.5 km in height.

  Wonder of the World - Neptune's moon Triton

Image: Triton is a big satellite 2706 km in diameter but its orbit is retrograde i.e. that its rotation direction is opposite to that of rotation of Neptune, this feature reveals that Triton is an object of the distant solar system, captured by the giant planet. Triton is also noticed by its geological activity and its seasons. Each season on Triton lasts about 41 years.

  Wonder of the World - Europa

Image: Color photography interpreted, taken between 1996 - 1997 by the Galileo spacecraft, at a distance of 671,880 km. Europa cracks open and close constantly with the tides, leaving glimpse of water vapor plumes. The red-brown color represents non-frozen areas of the crust, painted by minerals transported and distributed by the water vapor released from below. Blue represents the icy areas. White describes the fields covered with ice particles ejected during the formation of craters in the visible region. Credit: NASA Galileo Mission (1989-2003).
