  1. Tabetha Boyajian: The most mysterious star in the universe | TED Talk

    Something massive, with roughly 1,000 times the area of Earth, is blocking the light coming from a distant star known as KIC 8462852, and nobody is quite sure what it is. As astronomer Tabetha Boyajian investigated this perplexing celestial object, a colleague suggested something unusual: Could it be an alien-built megastructure? Such an extraordinary idea would require extraordinary evidence. In this talk, Boyajian gives us a look at how scientists search for and test hypotheses when faced with the unknown.

  2. CBC Ideas: Generation Mars, Part 1

    The day might well be approaching when humans set foot on Mars. We’ll be driven by a desire to find life — or what remains of it — and to colonize the planet. Stephen Humphrey and a stellar crew of authors, astronauts and Mars scholars confront the hazards, risks and challenges of getting humans to Mars, and then of surviving — and living — on the Red Planet.

  3. Space Oceans And Looking For Life

    All kinds of excitement over potential life in space in the last week. Light years away – maybe, but beguilingly – on a planet that looks amazingly like earth. Squint and you can picture Earth-like oceans and land out there. And much closer to home, on a moon in the rings of Saturn. Icy and cold on the outside. But inside, evidence of an underground ocean in space. Sending geysers to the surface. Lighting up astro-biologists’ fondest dreams. Maybe teeming with life. This hour On Point: the buzz over life in space, maybe on an Earth-twin way out there, maybe on a moon close to home. And the push to learn more.

  4. Earth 2.0? Billions Of Reasons Why It’s Possible

    The news from space this week gets our attention: There may be 40 billion Earth-like planets in our Milky Way galaxy. Planets like Earth “relatively common,” say the researchers. In the “Goldilocks” zone. Not too hot, not too cold. Forty billion chances for life to get started and evolve on Earth-like planets around Sun-like stars. Wow. Earth 2.0. And we thought we were special. Well, around here we are. The closest near-Earth – 12 light years away. And yet, just the idea of a single twin or sibling out there is amazing. Up next On Point: Maybe we are not alone. Contemplating Earth 2.0.

  5. BBC Discovery: A Trip Around Mars with Kevin Fong - Part One

    The planet Mars boasts the most dramatic landscapes in our solar system. Kevin Fong embarks on a grand tour around the planet with scientists, artists and writers who know its special places intimately- through their probes, roving robots and imaginations. This first part of the journey includes Mars’ gargantuan volcanoes, an extreme version of Earth’s Grand Canyon and the cratered Southern Highlands where future explorers might find safety from the Red Planet’s deadly radiation environment.

  7. Astronomycast 152: Binary Stars

    Did you know that our Solar System is a rarity with its single star. Astronomers believe that most star systems out there actually contain 2 or more stars – imagine seeing a sky with 4 suns. These binary and multiple star systems are a great target for new astronomers, and the dynamics of multiple stars keep astrophysicists busy too. Let’s take a look at what it would be like to live on Tatooine.

  8. Alan Boss: The Crowded Universe

    Host: Commonwealth Club Location: San Francisco, CA Event Date: 03.13.09 Considered a leader in the search for planets outside our solar system, Alan Boss says we are at a turning point in our search for extraterrestrial life.

    He expects we are on the verge of finding many different Earth-like planets across the universe, and he expects it will be common to find life on those planets. He shares his ideas for how the United States can be on the forefront of the next great discovery: life on another planet.

  9. Astronomy Cast - Ep. 125: A Zoo of Extrasolar Planets

    Dreaming up new planets is a favorite pastime of science fiction writers, but the universe often has them beat – coming with planets in place and forms that we had quite thought to imagine. Today we know of 228 stars orbiting alien stars, and in this episode we will look at the diversity of these worlds, from Mushy Lava covered planets to Icy Giants to the hottest of hot Jupiters.
