TRAPPIST-1 exoplanet system,illustration
TRAPPIST-1 exoplanet system. Illustration of two of the Earth-sized exoplanets in the TRAPPIST-1 system transiting their parent star. The planets (TRAPPIST-1b and TRAPPIST-1c) are the black dots passing across the face of the star as seen from Earth. The atmospheres of the planets were studied using NASA's Hubble Space Telescope. The results indicate an increased chance of these worlds being habitable. Spectroscopic analysis revealed a low concentration of hydrogen and helium in the planetary atmospheres. The planets orbit a red dwarf star that is at least 500 million years old,located 39 light years away in the constellation of Aquarius. This rare double transit occurred on 4 May 2016. The planets were studied as part of the SPECULOOS survey
