Appropriate to Episode #13, given the superstitious associations of that particular number, our guest today, Guy P. Harrison, is a debunker of superstitions and paranormal beliefs of all stripes. He joins Justin Trottier at The Star Spot to discuss his newest book 50 Popular Beliefs That People Think Are True. After an introduction to skepticism, why it's vitally important and how it differs from simply cynicism or denial, the two focus down on a variety of exciting specific beliefs: ancient aliens, modern UFOs, abductions, astrology, and the moon landing hoax. Harrison explains what convinced him to give up his belief that ancient aliens visited the Earth. He explains what we can learn about psychology and culture by looking seriously at alien abduction experiences. He confronts the most effective arguments of the moon landing hoax community and finally explains why we shouldn't take our newspaper horoscopes too seriously.
In Current in Space we comment on discussions from the 100 Year Starship initiative which seeks to prepare for interstellar travel within a century. At a recent symposium everything from new possibilities for warp drives to a debate about whether religion should accompany humanity was on the table. Finally, we provide an update on the status of the B612 Foundation's Sentinel mission, a sun-orbiting telescope that will increase our ability to track dangerous asteroids on potential collision courses with Earth.

Our guest today is Julian Barbour who joins Justin Trottier at The Star Spot to share his unique insights into the elusive mystery of time. He explains how new perspectives and research he is leading on time - which take seriously the puzzling implications of the Many World interpretation of quantum mechanics - may herald a new revolution in physics. The two explore the paradoxes of simultaneity and duration, asking how we know a second today is the same as a second a billion years ago. They then discuss Barbour's own personal paradox, in which his belief that time is illusory exists alongside his fascination with human history. In his own eccentric, provocative and illuminating style, Barbour finally takes listeners on a tour of platonia, a new concept in which existence is turned into a series of nows - or time capsules - and time is intricately connected to every activity in the universe.
Barbour is a theoretical physicist. Uniquely, he contributes to various fields without holding an academic position. He works part time as a translator and lives on a farm north of Oxford village. He’s been a visiting professor at the University of Oxford since 2008. Barbour holds an honorary doctorate from the University of Buckingham and is the author of a number of books, including Absolute or Relative Motion?, The Discovery of Dynamics, and The End of Time. His interests include quantum gravity, the history of science, and of course time
In Curent in Space we remind listeners not to miss the final days of the Perseid Meteor Show and provide an update on the first few Sols of the Curiosity rover which is now sending its first colour images from the Red Planet.

Our guest today is Professor Sarah Symons who joins Justin Trottier at The Star Spot to enlighten us about ancient Egyptian sophisticated conceptions of the night sky. The conversation ranges from understanding the intimate interplay between the supernatural and the scientific, to the practical uses of the stars for such purposes as predicting the flood of the Nile, and to the role of special classes of stars in ancient Egyptian myth and ritual.
Dr. Symons shares her enthusiasm in detailing how the night sky was at the centre of Egyptian religion. Pharoahs sought to transform themself into celestial beings, while the very body of one goddess formed the foundation of the Egyptian conception of celestial regularities. To close their conversation, the two reflect on why ancient Egypt continues to catalyze so much wild and crazy pseudoscentific and pseudoastronomical theorizing.
In Current in Space we discuss the illuminating findings from the nineth collection of UFO files recently turned over by the British government, then prepare for the August 6th landing of the Mars Science Laboratory Curiosity Rover by exploring the many unique attributes of this most exciting mission to the red planet.

Episode 6: Zooniverse & Citizen Science: How 300,000 Average People Became Astronomers, with Chris Lintott
Our guest today is Christopher Lintott, an astrophysicist, a researcher in the Department of Physics at the University of Oxford and a junior research fellow at New College. also at the University of Oxford. A fellow of the Royal Astronomical Society, Dr. Lintott`s work focuses on galaxies and star formation. He is the co-presenter of the BBC series The Sky at Night and a co-author of the book Bang! – The Complete History of the Universe co-authored with Patrick Moore and Brian May. It’s this focus on public engagement, and in particular the concept of citizen science that we’ll get into today, because most excitingly, Dr. Lintott is also Director of the astronomy crowdsourcing projects known as Zooniverse and Galazy Zoo, which have turned hundreds of thousands of people from around the world into scientists and astronomers.
In this discussion with Justin Trottier, the two discuss the emergence and growing sophistication of citizen science projects like Galaxy Zoo and Zooniverse. From sorting galaxies with Galaxy Zoo to identifying lunar craters with Moon Zoo to searching for planets and signs of life, not to mention a growing number of non-astronomy focused projects, Dr. Lintott explains the significant participatory impact being made daily by hundreds of thousands of people. Whether through basic categorization or unnanticipated observations like the discovery of the mysterious galaxy-like "Voorwerp," a growing army of citizen scientists are directing telescope time and providing data for research papers. The two also discuss the motives propelling this new development, and how they might grow a citizenry better informed by the tools of science.
In Current in Space we provide a final reminder about the upcoming Transit of Venus before turning to the thrilling conclusion of Dragon's landmark visit to the International Space Station. We then cover stories of life and death in the universe, highlighting the future merger of our own Milky Way with its nearest neighbour Andromeda. And finally we introduce a new Entertainment segment which will feature books, films, music and other areas of pop culture that connect to astronomy and space exploration. In particular, we tell how Haydon Planetarium's Neil deGrasse Tyson scored a victory for scientific accuracy in Hollywood when he convinced film director James Cameron to get the sky right.
