On Halloween night, 2003, a young boy named Vincent Ledvina is walking home after a cold midwestern evening of trick-or-treating. He looks up and sees something bright and green shimmering across the sky. “Is that the aurora?” he asks his parents. They aren’t sure. But young Ledvina, having seen the wonders of the upper atmosphere with his own eyes for the first time, is hooked.

Now a second-year Ph.D. student in Space Physics at the University of Alaska Fairbanks, Ledvina studies the aurora borealis. He is working to understand the intricacies of these beautiful—and even life-changing—natural phenomena using both NASA and citizen-sourced data. 

Mack Hughes defended his thesis on March 5th, titled “Direct and cascading effects of sea star wasting on rocky intertidal communities.”

In 2013 and 2014, sea star wasting caused a mass mortality event on the coasts from Alaska to Mexico. This phenomenon decimated many populations, affecting twenty species of sea stars.
