"Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a devastating cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? In Dark Matter and the Dinosaurs, Lisa Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter embedded in the Milky Way. In a sense, it...

In 1957, as Americans obsessed over the launch of the Soviet Sputnik satellite, another less noticed space-based scientific revolution was taking off. That year, astrophysicists solved a centuries-old quest for the origins of the elements, from carbon to uranium. The answer they found wasn't on Earth, but in the stars. Their research showed that we are literally stardust. The year also marked the first conference that considered the origin of life...

A long, long time ago, when the earth was extremely hot, a huge amount of vapor was released, creating clouds. As the clouds got bigger and heavier, it started to rain. Three of those raindrops were brothers who came down to cool the hot earth and traveled, as water does, to every corner of the earth, including apartment building pipes and muddy rivers. Written by a scientist, this is a great book for all curious children and budding young explorers....

Drawing on the current cross-pollination of geology, biology,...

It's the longest class...

Before the universe was formed, before time and space existed, there was ... nothing. But then ... BANG! Stars caught fire and burned so long that they exploded, flinging stardust everywhere. And the ash of those stars turned into planets. Into our Earth. And into us. In a poetic text, Marion Dane Bauer takes readers from the trillionth of a second when our universe was born to the singularities that became each one of us, while vivid illustrations...
