Show me science: The wonders of astronomy and space

Saturn - lord of the rings: Saturn, second largest of the gas giants, rules a dazzling domain. The rings of Saturn are billions of moonlets - from grains of dust to rocks the size of trucks. The planet is so light it would float in water. Titan, Saturn's greatest moon, is bigger than the planet Mercury. Students will see detailed images and discover fascinating details about this mysterious planetVenus - the hostile planet: At one time, Venus might have been Earth's twin, but scientists speculate that a maturing Sun doomed Venus. It is a lifeless planet with a dense, choking atmosphere with temperatures that could melt lead. Its environment is brutally hot and is constantly being covered by molten lava oozing from thousands of volcanoes. Constantly shrouded in cloud, Venus could once have been Earth's twin with oceans and continents, even simple life, but as the Sun matured, Venus became the hottest planet in our Solar SystemMercury - the inside track: Baked and irradiated, Mercury is a cratered world; pock-marked by impactors that rained from space during the early development of our Solar System. With double sunrises, its day is twice as long as its year. Mercury's orbit is now perpetually shadowed from the scorching Sun; scientists think there may be ice deposited by comets. In contrast, the un-Earthly Venus is a lifeless planet with a dense, choking atmosphere with temperatures that could melt leadMars - the red planet: Although Mars is about half the size of Earth, it takes nearly twice as long to orbit our Sun. NASA's 21st century inter-planetary robots landed on the once watery surface and sent back images and collected data. Coupled with Earth-bound complex telescopes, multi-disciplinary studies continue to enhance our knowledge of our closest neighbor
