The most important part tells you how to get home.Written in the second person, the text allows the reader to participate in every aspect of the journey, from packing ("don't forget your diary and plenty of food") to liftoff (at first you'll feel heavy; don't worry") to traveling through space (where "the moon glows like a pearl in the black, black sky").

And Christensen's artwork glows with the light of the stars he studied.Galileo's contributions were so numerous—the telescope! the microscope!—and his ideas so world-changing—the sun-centric solar system!—that Albert Einstein called him "the father of modern science." But in his own time he was branded a heretic and imprisoned in his home. He was a man who insisted on his right to pursue the truth, no matter what the cost—making his life as interesting and instructive as his ideas.

Then join the thrilling Voyager missions to explore the four gaseous outer planets: gigantic Jupiter, ringed Saturn, tilted Uranus -- the planet "lying on its side" -- and windy Neptune. You will finish your journey at distant Pluto, then visit the asteroid belt and examine comets, the "dirty snowballs" in space.A companion volume to Simon's landmark series of individual books about each of the planets, the sun, stars, and other space sights, Our Solar System will introduce you to some of the most amazing mysteries in the universe.

    Butterflies can't survive cold weather, so when winter comes, many butterflies fly to warmer places. They migrate.

    Henrietta spent years measuring star positions and sizes from photographs taken by the telescope at the Harvard College Observatory, where she worked. After Henrietta observed that certain stars had a fixed pattern to their changes, her discovery made it possible for astronomers to measure greater and greater distances—leading to our present understanding of the vast size of the universe.An astronomer of her time called Henrietta Leavitt “one of the most important women ever to touch astronomy,” and another close associate said she had the “best mind at the Harvard Observatory.” Henrietta Leaveitt's story will inspire young women and aspiring scientists of all kinds and includes additional information about the solar system and astronomy.
