First stars in the universe left a unique signature

June 30, 2015- 
Determining the chemical abundance pattern left by the earliest stars in the universe is no easy feat. A Lawrence Livermore National Laboratory (LLNL) scientist is helping to do just that.The first stars in the universe formed about 400 million years after the Big Bang (estimated at 13.8 billion years ago). Inside of these stellar furnaces, nuclear processes fused the hydrogen and helium made...

Planets around stars are the rule rather than the exception
