Florida Tech astrophysicist Howard Chen is offering new insights to help aid NASA's search for life beyond Earth. His latest theoretical work investigates the TRAPPIST-1 planetary system, one of the most widely studied exoplanetary systems in the galaxy. It has captured scientists' attention for its potential to host water, and thus possibly life, on its planets. Now, he's offering an explanation for why telescopes have yet to find definitive signs of either.
