Due to GJ1214b’s proximity to our Solar System, along with the relatively small size of its host star, the exoplanet is one of the most easy to observe, transiting super-Earths.
The planet GJ 1214b, shown here in an artist's conception with two hypothetical moons, orbits a "red dwarf" star 40 light-years from Earth. GJ 1214b has a radius of about 2.7 times that of Earth and is about 6.5 times as massive, putting it squarely into the class of exoplanets known as super-Earths. 3D modeling of GJ1214b's atmosphere: vertical mixing driven by an anti-Hadley circulation 2015 CHARNAY B., MEADOWS V. & LECONTE J. ApJ, accepted arxiv Observations of Exoplanet Atmospheres 2015 CROSSFIELD I. GJ 1214b, also known as Gliese 1214b, is 42 light years from Earth and was discovered in November 2009. GJ 1214b is classified as a water-world, and is the only example of such a planet yet to be discovered.

Scientists have characterized the atmospheres of two nearby exoplanets: the super-Earth GJ 1214b and the Neptune-sized exoplanet GJ 436b.

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.

The transmission spectrum of GJ1214b is striking: it is completely featureless at infrared wavelengths, with none of the patterns of spikes and dips that this sort of spectrum normally has. Much effort has been focused on using transmission spectroscopy to characterize the atmosphere of the super-Earth archetype GJ1214b (refs 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17), but previous observations did not have sufficient precision to distinguish between two interpretations for the atmosphere. Gliese 1214 b is an exoplanet that orbits the star Gliese 1214. This planet is usually called GJ 1214 for short, but the majority of the public refer to this 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. Clouds in the atmosphere of the super-Earth exoplanet GJ1214b Kreidberg et al. 2014 • 2014Natur.50569K IRSF SIRIUS JHK s Simultaneous Transit Photometry of GJ 1214b Comparison of the size of Earth, exoplanet GJ1214b, and Neptune (License: CC-BY-SA, by Aldaron) The field of extra-solar planet research is still a young one, but progress over the last few years has been startling.
In 2012, scientists discovered an exoplanet named 23.55 Cancri that was roughly 2 times the size of earth, that has a crust made of diamond
23 Dec 2009 The newfound world, GJ1214b, is about 6.5 times as massive as the smaller, cooler, and more Earthlike than any other known exoplanet.”. 1 Dec 2010 The exoplanet, which is about 2.6 times as wide as Earth and about six Bean tracked GJ 1214 b through two of those planetary transits using
In addition to secondary eclipse observations, the broadband transmission spectrum of the super-Earth GJ1214b is also presented. The transmission spectrum

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. But this latest exoplanet, GJ1214b, has something else, too: an atmosphere about 200 km thick.

A little over two years ago, astronomers at the Harvard-Smithsonian Center for Astrophysics discovered an exoplanet that we agreed was worth some extra attention.The planet, designated GJ 1214b, is only 2.7 times the diameter of Earth — one of the smallest exoplanets found — and orbits just over a million miles from its star (compare to Earth’s 92 million miles) in a zippy 38-hour
