The NASA Messenger spacecraft is sending the first pictures back of Mercury. These are the highest resolution photos we have ever seen and their available at NASA’s website. So, what do these images reveal? What about volcanic activity on the planet? And how close is it to the sun? Also, don’t miss what’s in the night sky in this first full week of April. Highlights include Venus, Mercury and Saturn along with constellations pointing to Summer.  All this and more on this week’s Sky Talk.[audio: st20110404.mp3]
