Light from the Edge of Time 

When did the first stars in the universe form and how can we observe them? 

By employing fast robotic telescope technology and observing the light from massive explosions called 

gamma-ray bursts, we have the capability to observe the very first stars in the universe. Nuclear processes in 

these stars led to the formation of the chemical elements that make up matter (us included!).
