Summary edit

Description
English: Your eyes are fine-tuned by thousands of years of evolution to see what is called visible light. But this makes up only a tiny fraction of all the light out there.

Even though invisible, the light you cannot see plays a significant role in your life, from helping you communicate over long distances, having safe plane landings in the fog or getting your broken bones checked.
When it comes to space, whole new realms are uncovered by this invisible light. Join ESO astronomer, Suzanna Randall, in the latest episode of Chasing Starlight and discover what different types of light reveal about the Universe.
