High Energy Universe

A revolution has been taking place in the world of cosmology.

Cosmic rays bombard the earth every day, but until now, where the enigmatic particles come from and what causes them remained if not a exactly a mystery, then mainly theoretical.

In this week’s Frontiers, Peter Evans travels to the famous old town of Heidelberg to meet the physicists who have opened up the wild west of astrophysics by building their own telescope and getting results most scientists can only dream of.
