The Hubble telescope, with it's new upgrades can see much farther than it's previous version, extending the vision some 200 million light years further back in time, but what it can't detect are radio frequencies. So when a supernova occured that could only be detected in the radio spectrum, Hubble showed it's limitations. On this week's SkyTalk learn about the different ways Hubble can be used and the different levels in the visual spectrum. Also learn about winter, spring and summer constellations that you can look for in the night sky.
