[1111.2628] Optical to near-infrared transit observations If it is the latter, it is a completely new kind of planet . In the case of a. It is thought that this planet is either a mini-Neptune, consisting of a rocky core with a thick, hydrogen-rich atmosphere, or a planet with a composition dominated by water. Observations by NASA's Hubble Space Telescope have added a new type of planet to the mix. The aim of this paper is to measure these variations. 1. GJ1214b, shown in this artist's view, is a super-Earth orbiting a red dwarf star 40 light-years from Earth. GJ1214b is made up entirely of water, but the average atmospheric temperature is 200 degrees celsius - a temperature in our own atmosphere at which water would boil . Explore the latest videos from hashtags: #atmosphericpressure, #atmospherepressure . "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. A planet forming at the position of GJ1214b should have been heated such that volatile elements like hydrogen reach their escape velocity and leave the planet. "GJ1214b is like no planet we know of," astronomer Zachary Berta said. Credit ESO/L. Among our solar system's inhabitants, Neptune is the planetthat most closely resembles GJ 1214b, Bean said. GJ1214b: water-world or mini-Neptune? Another similar planet is dubbed GJ1214b. GJ 1214b is classified as a water world and is the only example of a planet whose entire surface is covered by water that is found today. "A huge fraction of its mass is made up of water." GJ1214b was discovered in 2009 by the ground-based MEarth (pronounced "mirth") Project, which . This makes GJ1214b one of the two smallest transiting worlds astronomers have discovered, the other being CoRoT-7-b.

"GJ1214b is like no planet we know of," astronomer Zachary Berta said. Scientists have catalogued nearly 2,000 exoplanets around stars near and far. named GJ1214b, passed in front of it every 1.6 days. The planet, composed almost entirely of water, is larger than earth but smaller than the planet Uranus and is said to be so hot that a thick layer of steam atmosphere engulfs it at all times. position of GJ1214b. The term ocean world is also used sometimes for astronomical bodies with an ocean composed of a different fluid or thalassogen, such as lava (the case of Io), ammonia (in a eutectic . The planet known as GJ1214b located just 40 light-years from Earth was discovered back in 2009 by David Charbonneau . . 2009). With a mass (M p = 6.6M) and radius (R p = 2.7R) between those of Earth and Neptune, and a likely equilibrium temperature (T eq =500K) cooler than for most transiting plan-ets . New observations from the NASA/ESA Hubble Space Telescope show that it is a water world . The peculiarity of the planet is that it is entirely made of water with little to no solid mass. New observations from NASA's Hubble Space Telescope show that it is a waterworld enshrouded by a thick, steamy atmosphere. Our solar system contains three types of planets: rocky, terrestrial worlds (Mercury, Venus, Earth, and Mars); gas giants . It could be (1) a mini-Neptune with a H/He gas envelope; (2) a "water world" with a water-rich and ice-dominated interior and a water-vapour-dominated envelope; or (3) a rocky planet with an atmosphere mainly consisting of H 2. GJ1214b represents a new type of planet, like nothing seen in our solar system . Astronomy Science ~ GJ 1214 b is a Super-Earth planet orbiting GJ 1214. The 'super-Earth', which has a hot, steamy atmosphere, was categorised by Harvard-Smithsonian Center for Astrophysics (CfA) scientist Zachory Berta and others. Astronomers have discovered a new 'water world' planet, named GJ1214b, with a thick, steamy atmosphere that they believe could support life. HD 20782: A Highly 'Eccentric' Planet About 117 Light-Years From Earth - Observed. Calada ENLARGE. Because scientists say the extrasolar planet dubbed GJ1214b represents a brand new classification of planet: a veritable world of H 2 O, encased within a thick atmosphere of water vapor. GJ1214b is thought to be either a mini-Neptune with a thick, hydrogen-rich atmosphere, or a planet with a composition dominated by water. GJ 1214b, also known as Gliese 1214b, is 42 light years from Earth and was discovered in November 2009. GJ1214b orbits its star once every 38 hours at a distance of only two million kilometres 70 times closer to its star than the Earth is to the Sun. 2. Water Planet (GJ1214b) The weirdest planet ever found in our universe is a planet known as " GJ1214b " which has been nicked named as the "water world". If GJ1214b really is dominated by water, it would be surprising that it has been found within its star's snow line. The conclusion most consistent with the data is a dense atmosphere of water vapor. The resulting density suggests that GJ1214b is composed of about three-fourths water and other ices, and one-fourth rock. 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 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. 1 Tracks. In distance space, a water world: Hubble reveals a new class of extrasolar planet 21 February 2012 GJ1214b, shown in this artist's view, is a super-Earth This could mean one of two things: GJ1214b either has a hydrogen-dominated atmosphere with a cloud or haze layer that makes the atmosphere opaque in infrared wavelengths; or it is a water-rich planet with an atmosphere dominated by water vapour (de Mooij et al. While our planet completes a full swing in roughly 365 days, GJ1214b does one in 38 hours. "GJ1214b is like no planet we know of," astronomer Zachary Berta said. The planet, named GJ1214b, is not merely covered with water like our oceans; most of it is water. New observations by NASA's Hubble Space Telescope suggest that GJ 1214b is a watery world enshrouded by a thick, steamy atmosphere. In the case of a hydrogen-rich atmosphere, molecular absorption and scattering processes may result in detectable radius variations as a function of wavelength. For that reason, scientists have nicknamed the planet "the waterworld". "A huge fraction of its mass is made up of water." We have obtained observations of the . Cloudy with a chance of salt clouds. GJ1214b is thought to be either a mini-Neptune with a thick, hydrogen-rich atmosphere, or a planet with a composition dominated by water. "Being so close to its host star, the planet must have a surface temperature of about 200 degrees Celsius, too hot for water to be liquid," says David Charbonneau, lead author of the paper .
