At the End of the Rainbow
'Visible Light' is what we call the range of colours that humans can see with their eyes. Visible light is just a tiny portion of all light, so astronomers have built special telescopes to see things that human eyes can't! For this picture, three different telescopes were used and each picked up a different type of light.
