  1. Astronomycast 145: Interstellar Travel

    In science fiction it’s easy to hop into your spaceship and blast off for other stars. But the true distances between stars, and the limits of relativity make interstellar travel almost impossible with our current technology. What would it really take to travel from star to star, exploring the galaxy?

  2. Why Not to Fear Black Holes with Astronomer Ian Morison

    Black Holes seem to have bad press that is largely undeserved. This lecture with professor Ian Morison explains what Black Holes are, and how we can discover them even through they can’t be seen.

    This program was recorded in collaboration with Gresham College, on October 27, 2010.

    Gresham Professor of Astronomy Ian Morison made his first telescope at the age of 12 with lenses given to him by his optician. Having studied Physics, Maths and Astronomy at Oxford, he became a radio astronomer at the Jodrell Bank Observatory and teaches Astronomy and Cosmology at the University of Manchester.

    Over 25 years he has also taught Observational Astronomy to many hundreds of adult students in the North West of England. An active amateur optical astronomer, he is a council member and past president of the Society for Popular Astronomy in the United Kingdom.

    At Jodrell Bank he was a designer of the 217 KM MERLIN array and has coordinated the Project Phoenix SETI Observations using the Lovell Radio Telescope. He contributes astronomy articles and reviews for New Scientist and Astronomy Now, and produces a monthly sky guide on the Observatory’s website.

  3. Sir Roger Penrose | The Road to Reality: A Complete Guide to the Laws of the Universe

    Sir Roger Penrose is Emeritus Rouse Ball Professor of Mathematics at the University of Oxford and is the best-selling author of The Emperor’s New Mind. He is the recipient of numerous prizes and awards, most notably the Wolf Prize in physics, which he shared with Stephen Hawking for their "development of the theory of general relativity, in which they have shown the necessity for cosmological singularities and have elucidated the physics of black holes… enlarging our understanding of the origin and possible fate of the Universe." Penrose was knighted in 1994 and currently lives in Oxford, England.
