Enveloped in an atmospheric cocoon, our planet's biosphere supports billions of different life forms. In total contrast, the lifeless moon doesn't have enough gravity to retain an atmosphere. Its surface shows traces of impact craters, many of which formed 4.5 billion years ago, when swirling matter condensed around the sun to create the solar system. The Moon, Meteorites, and Solar System Gallery features some of the oldest Earth rocks , a stunning new collection of moon rocks , and the National Museum of Natural History's world-class collection of meteorites and rare rocks from Mars . Students explore the intricate puzzle of the birth of our solar system 4.6 billion years ago.
Students can also communicate with the hosts via fax , e-mail , and live Internet chat .
