Hubbleshjälp hittat bevis på kol-dioxid i atmosfären runten exoplanet.Astronomerna Planeten har fåttnamnet GJ1214b ochligger ungefär 40ljusår från oss.

GJ1214b was the first first super-Earth exoplanet discovered by MEarth. It orbits the M dwarf GJ1214, which is a very small star that is very nearby. Because of

Exoplanet Type: Water World. Mass: 6 to 7 x Earth Diameter: 2.7 x Earth. Distance from host star: 1.3 million miles (2 million km) Orbital Period: 1.58 days. Atmosphere: A thick atmosphere primarily composed of water vapor. Temperature: Around 200C (392F) Gravity: 0.9 x Earth's gravity NASA Exoplanet Archive is operated by the California Institute of Technology, under contract with the National Aeronautics and Space Administration under the Exoplanet Exploration Program. Scientists have characterized the atmospheres of two nearby exoplanets: the super-Earth GJ 1214b and the Neptune-sized exoplanet GJ 436b. 2019-07-15 New Subaru Telescope observations of super-Earth GJ 1214 b show that the exoplanet is likely to have a water-rich atmosphere..

It orbits the M dwarf GJ1214, which is a very small star that is very nearby. Because of English: Comparison of best-fit size of the exoplanet GJ 1214 b with the Solar System planets Earth and Neptune, as reported in the Open Exoplanet Catalogue Gliese 1214 b (often shortened to GJ 1214 b) is an exoplanet that orbits the star Gliese 1214, and was discovered in December 2009. Its parent star is 48 GJ1214b represents a new type of planet, like nothing seen in our solar system or any other planetary system currently known. Lists, Confirmed planets. Mass [M This is the first super-Earth exoplanet to have had its atmosphere analysed. The exoplanet, orbiting a small star only 40 light-years away from us, has a mass about 4 Sep 2013 “When combined with the findings of previous observations in other colors, this new observational result implies that GJ 1214 b is likely to have TrES-3b is an extrasolar planet with almost twice the mass of Jupiter, orbiting star Student Kellen Martin gathered data of exoplanet GJ 1214 b on the local extrasolar planet.

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.

We observed the transiting super-Earth exoplanet GJ1214b using warm Spitzer at 4.5μm wavelength during a 20 day quasi-continuous sequence in 2011 May. The goals of our long observation were to accurately deﬁne the infrared transit radius of this nearby super-Earth, to search for the secondary eclipse, and to search for other 2019-07-15 2013-12-31 6.1 Exoplaneten GJ1214b Du skal logge ind for at skrive en note I 2009 offentliggjorde en international gruppe af astronomer, der bl.a. talte Lars Buchhave fra Københavns Universitet, opdagelsen af en super-jord i kredsløb om en relativt lille stjerne, som befinder sig i en afstand af "kun" ca. 40 lysår fra Jorden. Exoplanet GJ1214b: What a wonderful world! 6 July 2012 by Phil Bull.

Access to of the transmission spectrum of the super-Earth exoplanet GJ1214b. 16 Dec 2009 gj1214b. Meet GJ 1214b, the most Earth-like planet ever found outside our solar system. It's not exactly Earth's twin: It's about six times bigger, 2 Dec 2010 An exoplanet discovered in 2009 is a 'super-earth' a bit like our own, but scientists say it's unlikely to be a good place to… 6 Mar 2015 Exoplanet atmospheres are the key for life detection on a planet beyond Clouds in the atmosphere of the super-Earth exoplanet GJ1214b. In addition to secondary eclipse observations, the broadband transmission spectrum of the super-Earth GJ1214b is also presented.

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 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 exoplanet GJ1214b.

GJ 1214 b, auch Gliese 1214 b, ist eine im Jahr 2009 entdeckte extrasolare Supererde.Bei seiner Entdeckung durch Zachory Berta war er der erdähnlichste bekannte Exoplanet. . Er ist knapp 40 Lichtjahre von der Erde entfernt und umkreist in 38 Stunden im Sternbild Schlangenträger den roten Zwerg GJ 1214, dessen Strahlung 200 Mal schwächer ist als diejenige der Son

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. An exoplanet is a planet that orbits a star beyond our sun. 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.
