Parents need to know that some episodes of this fascinating, well-made educational series include brief footage of natural disasters (such as San Francisco's 1989 earthquake) when addressing how other planetary bodies interact with Earth. Some language tends toward the dramatic -- like describing the sun as "violent" -- which might worry very young or sensitive viewers. Issues like global warming and other environmental issues also come up occasionally, the implications of which could frighten some young kids.
Positive messages:Teaches about the vast reaches of the universe. Somewhat U.S.-centric. Global warming and other environmental issues are discussed.
Violence & scariness:Some episodes include brief scenes of natural disasters (San Francisco's 1989 earthquake, for example), though the footage isn't graphic. The narrator sometimes describes galactic activity as "violent," etc.
