Danny Tallon: Supernova student

Danny Tallon is serious about space. After all, he'd love to go there.

Tallon, an undergraduate physics major at the University of Iowa, studies supernovas, which are exploding stars hundreds of billions of light years from Earth. The junior from Mondamin, Iowa, is a published author on two scientific papers that describe the curious behavior of a type of supernova whose explosions defy what physicists think should be happening.
