First light from exoplanets Two teams of astronomers have detected the light from extrasolar planets for the first time. Drake Deming of NASA's Goddard Space Flight Center and colleagues detected infrared radiation from HD 209458b, a planet that is orbiting a star some 153 light years from Earth in the constellation Pegasus. Meanwhile, David Charbonneau of the Harvard-Smithsonian Center for Astrophysics and co-workers observed infrared light from TrES-1, which is some 489 light years away in the constellation Lyra.
