    Temperatures of 800 billion degrees in the cosmic kitchen. It is among the most spectacular events in the universe: a merger of neutron stars. An international team of researchers with strong representation from the Technical University of Munich (TUM) has completed the first laboratory measurements of thermal electromagnetic radiation arising in such collisions. The resulting data enabled them to calculate the prevailing temperature when such stars merge.

    When two neutron stars collide, the matter at their core en...
