Melvyn Bragg and guests discuss the planet Saturn with its rings of ice and rock and over 60 moons. In 1610, Galileo used an early telescope to observe Saturn, one of the brightest points in the night sky, but could not make sense of what he saw: perhaps two large moons on either side. When he looked a few years later, those supposed moons had disappeared. It was another forty years before Dutch scientist Christiaan Huygens solved the mystery, realizing the moons were really a system of rings. Successive astronomers added more detail, with the greatest leaps forward in the last forty years. The Pioneer 11 spacecraft and two Voyager missions have flown by, sending back the first close-up images, and Cassini is still there, in orbit, confirming Saturn, with its rings and many moons, as one of the most intriguing and beautiful planets in our Solar System. With Carolin Crawford Public Astronomer at the Institute of Astronomy and Fellow of Emmanuel College, University of Cambridge Michele Dougherty Professor of Space Physics at Imperial College London And Andrew Coates Deputy Director in charge of the Solar System at the Mullard Space Science Laboratory at UCL.
In a time where we're all threatened by a rhetoric of hate from the people in power; A Gay And A NonGay challenges many of our differences head on and promises that no matter who you are, or what you're into (Bruce Springsteen or Britney), love is love and gay and nongays can be friends. </div><div><br></div><div>An independent podcast from James Barr (@imjamesbarr) and Dan Hudson (@DanHudson).
