Double-doubles aren't just at Timmy's! Come and discover some absolutely dazzling stellar pairs! What makes many of them so beautiful is their contrasting colours: we'll toss out the popular myth that all stars are white! Because of their different compositions, star colour varies from blue to white to orange to deep brownish red! The perceived colour difference of double stars is a very personal experience, and can vary slightly from night to night. Our springtime favourites are Cor Caroli and Mizar, while summer evenings are a great time to look at Albireo and 61 Cygni. As the nights deepen into autumn, we take a peek at Polaris and eta Cassiopeiae. So, double your fun, and join us! |

Were the lunar landings just a hoax? Does a full moon make people crazy? Can you sit at the bottom of a cresent moon and go fishing? We'll discuss these important issues as we take in our lovely little sidekick, the fascinating moon. We'll talk about terminators, limbs, maria, and ejecta as we gaze at mountain ranges, hills, valleys, vast plains-- and a bizillion craters. We'll show you where the Apollo 11 lunar mission landed. We might discuss the tides, and why our moon is the culprit, and why our day will eventually be around 1000 hours long! It's all good fun on those lazy summer evenings, when twilight slowly merges with the warm embrace of moonlit night. |

This spring, go ahead and say the s-word... Saturn! For that matter, how about another one: Spica. The planet Saturn and the star Spica are prominent in our southern sky this spring, and we'll look at both. Spica, in the constellation Virgo, looks like a single star, but is actually a multiple star,with two hot stars orbiting very close together. They're about 260 light-years away from Earth, or about 2500 trillion km. Saturn, a paltry 1.3 billion km away, is now sporting a hexagon-shaped (!) polar cap, shown at right. Scientists have not figured this one out yet; it is associated in some way with the dynamics of Saturn's polar jet stream. |
