Rethinking What Exo-planet Discoveries Mean

College of DuPage Astronomy professor Joe DalSanto joins First Light host Brian O'Keefe on the first Sunday of each month for a discussion of the night sky. They talk about what there is to see in the coming month. This month, Brian and Joe also spent some time talking about exo-planets, the planets researchers have found around distant stars.
