Sign Up for Our Server

CU Science Discovery and Fiske Planetarium are offering WHIMC summer camps for kids who would like to visit our crazy-cool “What-if” worlds and exoplanets and also work in teams to build mars habitats to later share on the theater dome. We also do all kinds of other STEM activities, including imagining and drawing exoplanets, making unique astronaut skins, experimenting with Universe Sandbox, taking real life science measures and more. We still have some spots left but not for long so sign up before it’s too late!

This is a great option for kids who don’t have their own computer or Minecraft account or who are new to the game and need support.

Minecraft Java Edition is required to play on the WHIMC server. iPads, xBox and Chromebooks won’t work… yet.
See our getting started page for more help.

Don’t have Minecraft? Can’t play Java Edition?
The PBS Nova Exoplanet Lab runs on any web browser and is a great solo activity alternative to learn about space exploration. It features real live scientists and alien rescue! Alternatively you can explore the International Space Station subject kit with Minecraft Education Edition.
