It used to be on either Discovery, National Geographic, maybe even Animal Planet. In each episode they featured a different alien world and talked about the physics of the planet and the star it orbited, as well as the theoretical life that might exist on it.
Some examples I remember of the planet's featured were: a gas giant that had feather-light animals floating in the upper atmosphere and a planet in a close orbit with a red star which periodically let out bursts of solar radiation and how the animals and planet had adapted to that.
Can anyone help?
