Feature Guest: David Paige

david1There was once a time when scientists believed that beyond the Earth there lied a largely dry, barren and inhospitable solar system. But now we think there is likely to be liquid water below the surface of Jupiter’s moons Ganymede and Europa, a warm salty ocean below the crust of Saturn’s moon Enceladus and recently NASA confirmed that ancient lakes once flowed on Mars.

As the solar system wettens, are we witnessing a paradigm shift with profound implications in our search for life. To help us answer that question today we’re joined at The Star Spot by the self-described “professional ice finder” David Paige.

Did you know human beings are not the only life forms aboard the ISS. Anuj explains. Then Tony builds on last episode’s description of a Tatooine-like exoplanet by introducing another Star Wars fan favourite. It seems the Kepler space telescope has discovered an object that is been dubbed the “Death Star” for while it is no battle station it may be just as destructive to nearby planets.
