After correcting for a ramp-like instrumental systematic, we achieve nearly photon-limited precision in these observations, nding the transmission spectrum of GJ1214b to be "GJ1214b is quite close to Earth, just 42 light years away, and it orbits its star in just 1.6 days." That fast orbit gave scientists the opportunity to record the exoplanet's flat spectrum, ruling out an atmosphere of simple hydrogen, water, carbon dioxide or methane. But this latest exoplanet, GJ1214b, has something else, too: an atmosphere about 200 km thick. “This atmosphere is much thicker than that of the Earth, Four CfA astronomers, Zachory Berta, David Charbonneau, Jean-Michel Desert, and Jonathan Irwin, together with six colleagues, used the Hubble Space Telescope to probe the atmosphere around the transiting super-Earth known as GJ1214b. This exoplanet has a mass of 6.5 Earth-masses and a radius of 2.7 Earth-radii, and it orbits a small M-dwarf But, that information is not always useful—as is the case with the exoplanet GJ1214b. "When an exoplanet passes in front of its star, light can be absorbed at some wavelengths by molecules in 2015-10-29 · “GJ1214b is quite close to Earth, just 42 light years away, and it orbits its star in just 1.6 days.” That fast orbit gave scientists the opportunity to record the exoplanet’s flat spectrum, ruling out an atmosphere of simple hydrogen, water, carbon dioxide or methane.

Its parent star is 48 light-years from the Sun, in the constellation Ophiuchus. As of 2017, GJ 1214 b is the most likely known candidate for being an ocean planet. Distinguishing Between Hydrogen-rich And Water-rich Exoplanets: Application To GJ1214b 2012 BENNEKE B. & SEAGER S. BAAS, 44, no 5, 103.06 GJ1214b, shown in this artist's view, is a super-Earth orbiting a red dwarf star 40 light-years from Earth. New observations from NASA's Hubble Space Telescope show that it is a waterworld enshrouded by a thick, steamy atmosphere.

These are the ﬁrst published WFC3 observations of a transiting exoplanet atmosphere. After correctingforaramp-likeinstrumentalsystematic, • the GJ1214b, a sub-Neptune suspected of hosting an atmosphere, has been observed to have a flat transmission spectrum • It is reasonable to assume the presence of clouds in exoplanet atmospheres is a wide spread phenomena, therefore understanding and characterization of exoplanet atmospheres is linked to our understanding of the clouds grism measurements of the transmission spectrum of the super-Earth exoplanet GJ1214b. These are the rst published WFC3 observations of a transiting exoplanet atmosphere. After correcting for a ramp-like instrumental systematic, we achieve nearly photon-limited precision in these observations, nding the transmission spectrum of GJ1214b to be "GJ1214b is quite close to Earth, just 42 light years away, and it orbits its star in just 1.6 days." That fast orbit gave scientists the opportunity to record the exoplanet's flat spectrum, ruling out an atmosphere of simple hydrogen, water, carbon dioxide or methane.

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.
