Geysers of water ice erupt from Saturn's moon Enceladus, the plumes are backlit by the sun while moon’s dark side is illuminated by reflected light from Saturn. The Cassini spacecraft flew right through the plumes to let its instruments 'taste' them.
Jupiter's moon Io is 778 million kilometers from the Sun. Except at its volcanic hot spots, Io's surface temperature is well below freezing. Instruments aboard the space probe Galileo measured infrared energy emitted by volcanic hot spots on the satellite's surface. Io was found to have at least 12 active volcanoes erupting lava at temperatures over 1200 degrees Celsius.
The totally eclipsed Moon of December 30, 1982 almost vanished completely from sight. Dust from the then-erupting Mexican volcano El Chichon was still suspended high in Earth’s atmosphere where it blocked most of the Sun’s rays from reaching the Moon. Credit and copyright: Fred Espenak.
Includes a full map of the world, and answers many questions such as - Where do the Sun & Moon go? What makes the wind blow and volcanoes erupt? How many countries and languages are there? Why is the Earth round and the sky blue? Do all plants have flowers and all rivers flow to the sea? Which is the biggest ocean and the brightest star?
Milky Way, a meteor, the moon and erupting volcano caught in one shot
This astonishing photograph would be pretty incredible if it was just of the lava but Mike Mezeul was lucky and skilful enough to also capture the Moon (on the right hand side), the Milky Way (in the center) and the meteor (the thin white vertical streak on the left)
