Summary

[edit]
Description
English: This artist’s impression shows how the newly discovered super-Earth surrounding the nearby star GJ1214 may look. Discovered by the MEarth project and investigated further by the HARPS spectrograph on ESO’s 3.6-metre telescope at La Silla, GJ1214b is the second super-Earth exoplanet for which astronomers have determined the mass and radius, giving vital clues about its structure. It is also the first super-Earth around which an atmosphere has been found. The exoplanet, orbiting a small star only 40 light-years away from us, thus opens dramatic new perspectives in the quest for habitable worlds. The planet, GJ1214b, has a mass about six times that of Earth and its interior is likely mostly made of water ice. It appears to be rather hot and surrounded by a thick atmosphere, which makes it inhospitable for life as we know it on Earth.
Español: Esta impresión artística muestra cómo puede lucir la súper Tierra recientemente descubierta que rodea a la cercana estrella GJ1214. Descubierto por el proyecto MEarth e investigado en profundidad por el espectrógrafo HARPS en el telescopio de 3,6 metros de ESO en La Silla, GJ1214b es el segundo exoplaneta similar a la Tierra del cual los astrónomos han determinado la masa y el radio proporcionando pistas claves sobre su estructura. También es la primera súper Tierra alrededor de la cual se ha encontrado una atmósfera. El exoplaneta, orbitando una pequeña estrella a sólo 40 años-luz de nosotros, abre espectaculares perspectivas en la búsqueda de mundos habitables. El planeta GJ1214b tiene una masa de unas seis veces la de la Tierra y su interior probablemente está compuesto por hielo de agua. Parece ser más bien caliente y rodeado de una densa atmósfera que lo hace inhóspito para la vida tal como la conocemos en la Tierra.
