Home This artist’s impression shows an imagined view of the three planets orbiting an ultra-cool dwarf star just 40 light-years from Earth that were discovered using the TRAPPIST telescope at ESO’s La Silla Observatory. In this view, one of the inner planets is seen in transit across the disc of its tiny and dim parent star. (ESO/M. Kornmesser/N.

Dr. Susan Lederer stands next to the UKIRT Telescope located on Mauna Kea on the island of Hawai’i, which was used to confirm the existence of the newly discovered exoplanets and constrain their orbital periods. Says Lederer, “For such a small, cool, star giving off so much of its light in the infrared, the UKIRT telescope, designed solely for infrared observations, was ideally suited for confirming the existence of these Earth-sized planets.”
