A Panoply of Constellations

The last of the spring stars are now inhabiting the night sky. It seems odd that in the beginning of September we can still see Spring stars, but it has to do with  how the sky is laid out.  If you start early enough in the evening you can find the last stars of one season and the beginning of another season. Keep an eye out for Arcturus, easily identifiable by its orange color, often mistaken for Mars. Also, the Obama administration has proposed visiting an asteroid as a stepping stone to visiting Mars. How long do you think it would take to get to Mars and back?  All this and more on this week’s Sky Talk.[audio: st20100906.mp3]
