Galileo's modern view of the cosmos gives rivals an opening to steer him into controversy and a fateful showdown with the Church. How a not-so-innocent dinner party conversation set Galileo on a collision course with history.

Using the newly refurbished Hubble Space Telescope, he¢s looking for some of the most distant objects ever seen to uncover the early history of our universe. Meanwhile, Roberto Abraham explains how we can push back even further to the very first galaxies -- and perhaps to the very first stars -- with a new generation of telescopes on the ground and in space.

Wilson is arguably the most important astronomical instrument since Galileo's telescope. Last month it was very nearly lost when a wildfire swept toward the mountain. The observatory was only recently declared safe. Astronomer Hal McAllister recounts the dramatic rescue effort and author Marcia Bartusiak explains why Mt. Wilson is the place where the modern universe was born. Wed, 19 Oct 2009 20:57:00 -0500 Ivan Semeniuk No The 100-inch Hooker reflector atop Mt.
