Exploring the Outer Reaches of Our Universe

Voyager 1 has been trekking for 33 years over 11 billion miles to get a good look at the outer planets of our solar system. It’s the first time we had done anything like this and now 33 years later we are still in contact with the craft and can detect what activity is going on at such a great distance. It’s a remarkable feat considering the conditions and distance. Right now it’s in between the inner boundary of the solar system and the outer boundary of solar system, but what does this mean? Could this be comparable to Neil Armstrong landing on the moon? Tuesday is both the winter solstice and a total lunar eclipse. Stay up late or get up early, and catch this exciting astronomical event. All this and more on this week’s Sky Talk.[audio: st20101220.mp3]
