The Star Spot

Feature Guest: Jim Bell

Does our solar system really have 35 or even 40 planets? Is Mars merely the moon with an atmosphere or is it actually an ancient Earth? From the red planet to the jovian moons and then out to Pluto, destination for the New Horizons space mission, today we're joined at The Star Spot by Jim Bell for a brief tour of our own special home, the solar system.

Jim Bell and Justin Trottier discuss early discoveries from the Curiosity rover showing evidence of clays that could only be formed in fresh water. And Professor Bell responds to Mars One, an audacious plan to send - and document via reality TV - a group of humans on a one way trip to Mars.

Current in Space

Following up on today's theme of our very own solar system, Anuj presents new discoveries on our beloved sun and Denise shares our growing understanding of the water and ice word of Europa.

Feature Guest: Christine Wilson

No neighborhood avoids change, and that certainly includes the neighborhood around stars. As the stars that populate galaxies form and develop through their life cycle, how exactly do they change the interstellar medium and drive galaxy evolution? and what larger processes are at play governing the interaction between stars and the galaxies they call home? To help us answer these questions today I’m joined at the star spot by Professor Christine Wilson


Current in Space
