After a blistering day of exploring, astronauts may relax with a nice cold glass of ice water from Mercury, the planet closest to the sun. Since there is no atmosphere there to spread the heat around, shadows in deep craters at the poles could hold ice deposited by early comet collisions.
Where do comets come from? There is a huge cloud of objects made of ice and rock encircling our solar system, called the Oort Cloud. It lies beyond Pluto and extends half way out to the next star. These objects occasionally bump into each other, sending one in towards the sun to become a comet like the recent Hale-Bopp comet.
Someday you may go ice fishing on Jupiters moon, Europa. Evidence is being constantly discovered that there is an ocean under the ice of Europa. The ice would keep the ocean from evaporating and huge tides caused by Jupiter would keep the ocean temperature above freezing. What kinds of life might there be in such a strange ocean?
A giant game of cosmic pool was played when the solar system was first formed billions of years ago. Neptune was hit by an asteroid so big it was knocked sideways on its axis. It orbits with one pole pointed at the sun. Venus was hit so hard it is almost upside down and is the only planet to spin backwards on its axis. And most astronomers believe the Moon was formed when an asteroid almost the size of Mars hit Earth and shot debris into orbit. I wonder who won the game and when is the next tournament?
