Multi-wavelength Universe Activity

When you look up at objects in the night sky you only see part of the picture; you see visible light. In reality, the universe is emitting light at a huge range of wavelengths from radio waves to gamma rays and everything in between. It is important for astronomers to compare the light of each type from an object such as a star or a galaxy as that tells us huge amounts about their composition and conditions.

To help students explore the multi-wavelength nature of astronomical objects, the UK Herschel website has a multi-wavelength universe activity with a bunch of educational resources for teachers. The activity was originally written in Flash and Chris North recently asked me to convert it to Javascript/HTML to make it easier to update and so that it would work on devices that don't support Flash (e.g. iPads/iPhones). In refreshing it I also made it responsive (it should reformat itself for narrow devices such as smart phones) and built in support for different languages (you'll be able to use it in Welsh at some point soon).

We made the whole thing open source and, if you've checked out a copy from Github, you can even run in a browser locally without needing an internet connection.

Let us know what you think. Please report bugs via Github or tell me on Twitter.
