Did we miss something on diversity?

Research shows a connection between kids' healthy self-esteem and positive portrayals in media. That's why we've added a new "Diverse Representations" section to our reviews that will be rolling out on an ongoing basis. You can help us help kids by suggesting a diversity update.

A lot or a little?

The parents' guide to what's in this TV show.

Positive Messages

Provides a lot of examples of how science, curiosity, and dedication can lead to exciting discoveries.

Positive Role Models

Features scientists and guests from across the globe and from a wide variety of backgrounds.


Violence is limited to animals attacking other animals, and the show explains the relationships between predators and prey. Sometimes here "animals" means alien creatures, so watching one alien attack another can be disturbing. 


Mild profanity is sometimes used: "bastard," "damn," etc.

What parents need to know

Parents need to know that Alien Worlds is a nature show that imagines what life is like on other planets and compares it to life on Earth. The show uses science to speculate how alien creatures might evolve and thrive within the environments on other planets. Then, it uses real life examples to illustrate scientific principles exhibited by these alien creatures. So the learning goes both ways: Alien Worlds uses what we know about life on other planets to illuminate unique examples of life on earth, from exotic animal species to untraveled places like underground caves or caverns deep under water.

don't let the title fool you

The tv show uses science of life on earth to predict what life on alien worlds could be like. However, most of the show doesn't even focus on alien life.... Continue reading

What's the story?

Alien Worlds is a science and nature anthology show that uses science to speculate what life might be like on other planets. The show starts with what's known about these distant planets: what the atmosphere might be like, how gravity might affect life, etc. Then it imagines how life might function in this unique environment, how it might eat, survive, and adapt. Animations of these creatures show what their day-to-day lives might look like, and then examples of life on Earth are shown to illustrate how natural principles can translate even over time and space.

Is it any good?

Alien Worlds' animated portrayal of alien life is fun on its own, but the show craftily uses its creations as a way to learn about life here on Earth. It starts with facts about these distant planets, illustrates how nature might exist there, and then doubles back to show how looking closely at things on this planet can help understand even the farthest reaches of the galaxy. Guests on Alien Worlds go paragliding, explore underground caves, and hang out with birds and bugs, and all of these things help illuminate principles of science and nature. Though the aliens are the main attraction, by the end of each episode, viewers should have a better understanding of nature in general, wherever it happens to exist.

Talk to your kids about ...

  • Families can talk about life on other planets. Why does Alien Worlds believe life on other planets exists? How do they go about speculating what life on other planets might be like? What are some example of how science and logic can help imagine alien creatures?

  • What were your favorite alien creatures? Did any of the creatures surprise you? What are some ways the aliens' lives differ from life on Earth?

  • Did you learn anything new about life on Earth? What were some places shown that you didn't know existed? Did you learn anything about animals on Earth that surprised you? Were any of the Earth animals stranger than the alien creatures?
