We knew some stars created large amounts of calcium, but no one really ever knew how...until now! Plus, astrophysicists believe they’ve finally seen evidence of the star that created one of the most important supernovas ever!

Hurricanes are just made up of clouds and wind moving in a certain pattern…so could we use a nuclear weapon to disrupt that wind enough to stop them?

NASA has put out the challenge: can YOU build software for a space robot? Along with that warm fuzzy feeling that you've helped humanity reach for the stars, a cash prize will be awarded to the winners.

Caitlin delivers the latest developments from around the universe, including Curiosity's latest drill, the low-down on that "secret" space plane, and the dimmest galaxy ever detected.

Massive stars die in fantastic explosions called supernovas. Most of them fit neatly into a few categories, but then there are the peculiars, a special group of supernovas that don’t quite fit in with the rest.

Jessi and Squeaks love science mysteries, and today they've teamed up with their friend, Dino, to try and solve one of the biggest mysteries of all: what happened to the dinosaurs?
