Warm nights provide a good opportunity to take in natural and manmade wonders overhead. All of the stars in the night sky are part of our spiral galaxy the Milky Way. We think of ourselves as a large disc, 100,000 light years in diameter. Do you really know what a light year is? How far is it? Also, how do you spot a satellite in the night sky, like International Space Station? All this and more on this week's Sky Talk.
