Caption: Light from two massive stars that exploded hundreds of millions of years ago recently reached Earth, and each was identified as a supernova by researchers at Southern Methodist University, Dallas. One exploded about 450 million years ago, and the other about 230 million years ago, said physics grad student Farley Ferrante, who made the initial observations. Both supernovae were spotted by the Robotic Optical Transient Search Experimentís ROTSE3b at McDonald Observatory near Fort Davis, Texas.
