Earlier this year, Galaxy Zoo expanded to include the infrared. Now Radio Galaxy Zoo involves looking at galaxies in yet another light. This time we are asking you to match huge jets – seen in radio emission – to the supermassive black holes at the centre of the galaxy that produced them. This requires looking at the galaxies in infrared and radio wavelengths. These galaxies are nothing like our own, and your classifications will allow scientists to understand the causes of these erupting black holes and how they affect the galaxy surrounding them.

Get involved now at http://radio.galaxyzoo.org – and have fun discovering black holes in our Universe.
