Star with seven possible Earth-like planets has UD connection

February 22, 2017 - When NASA announced in a news conference Wednesday, Feb. 22, that researchers had found seven potentially Earth-like planets orbiting a star 235 trillion miles away, John Gizis, a professor at the University of Delaware, got a big grin on his face. Gizis actually discovered that star in 1999. “It’s extremely exciting,” Gizis said from his office in UD’s Department of Physics and Astronomy. “It’s a very small and cool dwarf star. Because it’s temperature is so cool, it hadn’t been noticed before we saw it almost 20 years ago, even though it’s quite close to the sun.”
