Eventually, you’ll hit a thick layer of liquid water. [3] The star is rotating slowly, with a period that is most likely an integer multiple of 53 days. Researchers believe that the surface of the planet is warming up at 200 ° C. Theme by Garrett Gardner. [3] It is located at a distance of approximately 47 light years from Earth. [8][12], Discovered by the MEarth project and investigated further by the HARPS spectrograph on ESO’s 3.6-metre telescope at La Silla, GJ 1214 b is the second super-Earth exoplanet for which astronomers have determined the mass and radius, giving vital clues about its structure. Exotic Waters Gliese 1214 b (Often shortened to GJ 1214 b) is an exoplanet that orbits the star Gliese 1214, and was discovered in December 2009. On an ocean world like some believe GJ 1214 b to be, if you dive down to where pressures are high enough — say, 100,000 times Earth’s atmosphere — you might find yourself surrounded by unearthly cuboids of ice VII (pronounced “ice-seven”). Science, Health and Environmental Reporting Program Gliese 1214 b (thường được rút ngắn thành GJ 1214 b aka Ocean Planet) là một ngoại hành tinh quay quanh ngôi sao Gliese 1214, và được phát hiện vào tháng 12 năm 2009. At these high temperatures and high pressures, water cannot exist, on the surface, as a liquid. (In 2009, it was, in fact, only the second super-Earth to be discovered.). It was possibly a gaseous giant, but as it approached the Gliese 876, its mass ejections expelled its layers of gas, and it is still hot today, as the volcanic activities on its surface are visible. Its parent star is 48 light-years from the Sun, in the constellation Ophiuchus. Discovered in 2009, the planet is about 2.7 times Earth’s diameter and is almost 7 … Gliese 1214 is a dim M4.5 red dwarf in the constellation Ophiuchus with an apparent magnitude of 14.7. It’s not certain what GJ 1214 b actually looks like, but some astronomers think the outside of the planet is dominated by a thick atmosphere composed of water vapor. World's most comprehensive interactive database of extrasolar planets updated daily since 1995. As such, if there’s water on the surface or even near the surface, it’s likely been vaporized. Unlike terrestrial planets, the super-Earth doesn’t have a solid surface, making the height of the atmosphere difficult to define. [3], No transit-time variations have yet been found for this transit. "At the bottom of the water-rich atmosphere of Gliese 1214 b, water should be a super-critical fluid." Scientists figure the top of Gliese 1132b’s atmosphere is around 533 K, 260 °Centigrade, 500 °Fahrenheit; probably hotter at the surface. For that reason, scientists have nicknamed the planet "the waterworld". (Scientists call this ice Ih.) Living UFOs: Our Sky Is Their Ocean. Now imagine the situation on Gliese 1214 b. Gliese 1214 b on the background of the parent star. According to NASA, there exists probable evidence of a great number of extraterrestrial oceans, which means there is a vast potential for…. in the Arthur L. Carter Journalism Institute at New York University. It is probably at least three billion years old and a member of the old disk. ApJ 773, 144; … [3] Although GJ 1214 has a low to moderate level of magnetic activity, it does undergo flares and is a source of X-ray emission with a base luminosity of 7.4×1025 erg s−1. New Type of Alien Planet Is a Steamy 'Waterworld' GJ1214b, shown in this artist’s view, is a super-Earth orbiting a red dwarf star 40 light-years from Earth. This planet is usually called GJ 1214 for short, but the majority of the public refer to this... Gliese 1214 b is an exoplanet that orbits the star Gliese 1214. 2. Instead, atmospheric scientists introduce a concept called the scale height, a height determined by changes in the increase or decrease of atmospheric pressure by a set amount. GJ 1214 b is a “super-Earth,” a planet that’s bigger than Earth but likely still solid and terrestrial, rather than a gas giant. Credit: NASA, ESA, and D. Aguilar (Harvard-Smithsonian Center for Astrophysics). The star is about one-fifth the radius of the Sun with a surface temperature estimated to be 3 000 K (2 730 °C; 4 940 °F). Size: ~2.7 Earth radii Gliese 876 d is a planet orbiting the Gliese 876 15 light-years from Earth, it is a large planet, but it has a small mass, but it is a Super-Earth, and yet it is rather large, and its past is bizarre. "[13] The X-ray flux from the host star is estimated to have stripped 2–5.6 M⊕ from the planet over the lifetime of the system. On Earth, the scale height is about 6 miles (10 kilometers), while on Gliese 1214 b it is three times deeper, according to Narita.

As of 2015, GJ 1214 b is the most likely known candidate for being an ocean planet. If you make the pressure high enough, some of these ices can exist at room temperature — and some of these can exist at temperatures hot enough for water on Earth to boil. Go even deeper, and even with temperatures hot enough to melt metal you might find yourself in frozen clouds of ice X. Detailed information on planet GJ 1214 b orbiting around star GJ 1214. The Shortest Distance Between You and Science, A project of NYU's Science, Health and Environmental Reporting Program. The star is about one-fifth the radius of the Sun with a surface temperature estimated to be 3000 K (2730 °C; 4940 °F). The temperature of the stellar corona is estimated to be about 3.5×106 K.[10], In mid-December 2009, a team of Harvard-Smithsonian astronomers announced the discovery of a companion extrasolar planet, Gliese 1214 b, potentially composed largely of water and having the mass and diameter of a super-Earth. It is also the first super-Earth around which an atmosphere has been found. Your email address will not be published. Its luminosity is only 0.33% that of the Sun. As of 2017, GJ 1214 b is the most likely known candidate for being an ocean planet. These aren’t like Earth. Instead, atmospheric scientists introduce a concept called the scale height, a height determined by changes in the increase or decrease of atmospheric pressure by a set amount. Discovered by: David Charbonneau, et al. Gliese 1214 is a dim M4.5[4] red dwarf in the constellation Ophiuchus with an apparent magnitude of 14.7. Earth is really a world of rock and metal that just happens to be painted over with a thin coat of water. [12], The estimate for the stellar radius is 15% larger than predicted by theoretical models. It is located at a distance of approximately 47 light years from Earth. But if you go below that, you’ll probably start entering a much stranger world: a world of exotic ice. Gliese 1214 b may be rich in water, but this definitely is not the kind of water you'd want to be drinking! Ice VII has actually been found to naturally occur in diamonds, and some scientists think it exists deep within Jupiter’s moon Europa. The exoplanet, orbiting a small star only 40 light-years … Mass: ~6.2 Earth masses It is also the first super-Earth around which an atmosphere has been found. The planet orbits a small red dwarf star which has only 16% the mass of our own sun. When you look at Earth from space, oceans dominate it. › Larger image GJ1214b, shown in this artist's view, is a super-Earth orbiting a red dwarf star 40 light-years from Earth. It is also believed that the temperature on the planet is so high that life may not exist on the planet. A project of the [11] The star is about one-fifth the radius of the Sun[12] with a surface temperature estimated to be 3000 K (2730 °C; 4940 °F). Gliese 1214 b (GJ 1214 b) Holding the nickname of "the waterworld", and a size larger than that of the earth, it is an exoplanet that is believed completely covered in water. It is located at a distance of approximately 47 light years from Earth. Astronomers have now added one more to the list, and this one — a super-Earth dubbed Gliese 15Ab — ranks as one of the closest known exoplanets, circling its … The thick layer of Ice VII that covers the core GJ 1214b, also known as Gliese 1214b, is 42 light years from Earth and was discovered in November 2009. GJ 1214 B is known for being composed almost entirely of water, totaling approximately 75% of its mass while the other 25% is rock. “At the bottom of the water-rich atmosphere of Gliese 1214 b, water should be a super-critical fluid.” Unlike terrestrial planets, the super-Earth doesn’t have a solid surface, making the height of the atmosphere difficult to define. This ocean planet has a small amount of rockey surface in its core. As of 2012, "the given data does not allow us to conclude that there is a [second] planet in the mass range 0.1–5 Earth-masses and the period range 0.76–1.23 or 1.91–3.18 days. No, these ocean worlds are more like very large comets, where the majority of the planet’s mass is water. There’s a few known planets that could be ocean worlds, but today we’re looking at a single one: GJ 1214 b, orbiting a red dwarf within the Sun’s local neighborhood. [12] Its luminosity is only 0.33% that of the Sun. Surface climate: Water is wet “However, we may not be able to find hot ‘ice’ — high pressure-ices — inside of Gliese 1214 b.” Originally discovered in by the MEarth Project, which tracks more than 2,000 low-mass stars in search of planets, Gliese 1214 b was confirmed by the European Space Agency’s High Accuracy Radial velocity Planet Searcher in Chile. But do not think that you are destined to be in the water world, where a dense layer of water covers a modest rocky core. Gliese 1214 b (often shortened to GJ 1214 b) is an exoplanet that orbits the star Gliese 1214, and was discovered in December 2009. Required fields are marked *, Distinguished Writer in Residence, New York University. The planet is literally an egg cooker! GJ 1214 b is a “super-Earth,” a planet that’s bigger than Earth but likely still solid and terrestrial, rather than a gas giant. Your email address will not be published. But by playing with pressure, you can actually create at least 18 phases of ice, many with alien crystal shapes: cubes, pyramids, and some that don’t even form crystals at all but instead amorphous blobs. , a project of NYU 's Science, Health and Environmental Reporting Program in the constellation Ophiuchus with an magnitude..., 462 °C, 867 °F an apparent magnitude of 14.7 'd want to be discovered.....
