MP3 Download

Did you know that our bodies are really made of stardust? Since the first grade, Ken Croswell, an astronomer and Ph.D. from Harvard, has been totally fascinated by our solar system. Get caught up in his extraordinary enthusiasm as he discusses everything from Black Holes, brown dwarfs, the Milky Way, the red giant, quasars and collisions with floating matter. Croswell relates how vast our universe really is. "The observable universe does have an edge but the actual universe has no edge whatsoever. What is beyond our horizon, we don't know," exclaims Croswell. "The universe's expansion is not decelerating, it is actually accelerating." He addresses how pollution is a devastating occurrence with our planet. "Today it is very hard to see some of the stars. There is so much light pollution. Most people have never seen our own galaxy, the Milky Way, which is sad." Croswell discusses a two-year odyssey, from inception to publication, of his incredibly awesome book comprised of photographs of space from six different continents. (hosted by Michael Toms)
