March 3-9: Exploding stars. There are all kinds of ways for stars to explode. Big stars can stop producing energy; little stars can steal too much gas from their companions, or two of them can ram together.

March 10-16: Frosty geysers. The Cassini spacecraft is set to fly through some cold geysers this week -- tall plumes of water from one of Saturn’s moons. We’ll have details. And we’ll tell you how our Moon will butt heads with a star.

March 17-23: Competition. Our solar system has more planets than any other yet discovered. But a system in the constellation Cancer is catching up fast. We'll talk about this family of giant planets, plus take a look at some of the planetary goings-on closer to home on StarDate.

March 24-30: Moving family. Most of the stars of the Big Dipper are members of a big stellar family. The family isn’t as tight as it used to be, but it still moves through space together.

March 31: Planets galore. The roster of planets beyond our own solar system is closing in on 300. We’ll have details on one planet that may have survived a powerful collision, plus much more. Join us for tales of planets across the galaxy on StarDate.
