Time marches on except in astrophysics. Einstein taught us that time is a coordinate in space, and it's all relative. Learn about the weird physics of our universe that could make time travel possible. Standing in for Lynne Koplitz this week is J. Richard Gott, author of Time Travel in Einstein's Universe.

This year marks the 400th anniversary of Galileo's use of the first telescope. On this week's show, we reflect on how telescopes have changed our perception of our place in the universe, how small we are in size, space, and time. Our guests include Dava Sobel, author of The Planets, Vatican Astronomer Father Chris Corbally, and astronaut Paul Richards. We also discuss how they help astronomers discover new and interesting aspects of the universe, from Earth-like planets to supernova, from black holes to the Big Bang.

Space is now big business. Technology originally developed for the space program sometimes ends up in products for use on Earth, often in surprising ways. The 40,000 certified "Space Products" range from mattresses to medical devices, and have turned space into a multi-billion-dollar industry. Inspired by our excursions into the Final Frontier, entrepreneurs and inventors are turning stardust into gold.

What price do we put on knowledge? How does it profit a man if he learns about the universe, but goes to bed hungry? When the economy takes a downturn, should we still go up into space? NASA missions aren't cheap - sending astronauts into low Earth orbit or to the Moon, sending robotic spacecraft to explore the planets, and launching telescopes into space can cost millions or even billions of dollars. Lou Friedman, director of the Planetary Society, argues that even when the dollar is dear, the quest to explore our universe is priceless.

Starry starry nights, stormy and sun-filled days. Long summer days of picnics and ballgames are played out under a vast and gorgeous canvas of astronomical and meteorological curiosities. From the stories of the stars told by the ancients, to a recent mammatus cloud over CitiField in New York, learn about the phenomena in the summer skies that keep us looking up.

Geometry, physics, and the other sciences describe the world we live in, and artists often play with these properties in their own imaginative investigations. From the drawings of Leonardo Da Vinci to high-tech computer graphics, Neil and Lynne paint a picture of how science has inspired art through the ages.

Richard Branson has formed Virgin Galactic and is now taking reservations aboard the maiden voyage of SpaceShipOne. Would you spend the estimated $200,000 for a 45-minute trip into space? Neil and Lynne also discuss the mechanics of sex in space.

Neues vom Bestsellerautor von Das Universum für Eilige: Wie schaut der Kosmos auf die menschliche Zivilisation? In einer Zeit der gesellschaftlichen Spaltung blickt der Star-Astrophysiker Neil deGrasse Tyson mit der kosmischen Brille auf die Menschheit und zeigt auf, was uns auf der Erde politisch und kulturell zusammenschweißt. Gleichzeitg liefert er ein leidenschaftliches Plädoyer für wissenschaftliches und rationales Denken ab.
