Given the fact that there are perhaps 400 billion stars in our galaxy alone and perhaps 400 billion galaxies in the universe, it stands to reason that somewhere out there, in the 14-billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. The sheer enormity of the numbers almost demands that we accept the truth of this hypothesis. Why, then, have we encountered no evidence, no messages, no artifacts of these extraterrestrials?

In the aftermath of an asteroid impact, Earth’s power grid is damaged nearly beyond recovery. The survival of our world may well depend on energy sources collected from an abandoned undersea settlement beneath the icy surface of Enceladus. Earth-raised Colonel Carter Rhodes, in charge of Earth’s recovery efforts, calls upon Gwen Baré, a Venusian engineer, to regain control of the deserted moon outpost and collect fuel for Earth’s collapsing power grids.

This is a fascinating introduction to the history of Western astronomy, from prehistoric times to the origins of astrophysics in the mid-19th century. Historical records are first found in Babylon and Egypt, and after two millennia the arithmetical astronomy of the Babylonians merged with the Greek geometrical approach to culminate in the Almagest of Ptolemy. This legacy was transmitted to the Latin West via Islam and led to Copernicus's claim that the Earth is in motion.

On the evening of April 13, 1970, the three astronauts aboard Apollo 13 were just hours from the third lunar landing in history.

Thirteen is the shocking and miraculous true story of how the astronauts and ground crew guided Apollo 13 back to Earth. Expanding on dispatches written for The New Yorker, Henry S. F. Cooper Jr. brings listeners unparalleled detail on the moment-by-moment developments of one of NASA’s most dramatic missions.

When ancient people first sought to explain the mysteries of their own lives, they looked to the heavens. There, they saw a perfect reflection linking them directly with an omniscient universe.

When asked to explain Relativity simply, Albert Einstein himself once joked, “Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute. That's Relativity.” But when most normal people without advanced training attempt to study the subject seriously, they’re quickly weighed down by the mathematics…
