He received his undergraduate degree from Harvard and his doctorate from Oxford, where he was a Rhodes scholar.

Brazilian physicist Marcelo Gleiser is the author of the new book, The Prophet and the Astronomer: A Scientific Journey to the End of Time (WW Norton). In it he explores our relationship to the sky and how it has influenced religion and then in turn - science. He writes, 'one of my goals. . is to humanize science, to argue that our scientific ideas are very much a product of the cultural and emotional environment where they originate'.

Reston recently wrote a cover story for "Time Magazine," on the comet crash into Jupiter, before the crash became national news.

Astrophysicist George Smoot. Since 1974 he's worked on NASA's Cosmic Background Explorer (COBE) satellite, leading the instrument team that detected cosmic "seeds." In 1992 he announced that he and a team of researchers had detected the biggest, oldest objects ever observed in the universe, the "cosmic seeds" that were the origin of galaxies and clusters of galaxies.

Journalist Timothy Ferris spent twelve years writing his new history of the galaxy. He explores ancient and contemporary theories of the universe, and how philosophy and theology have influenced scientific advancements.
