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. Its parent star is 48 light-years from the Sun, in the constellation Ophiuchus. 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. in the Arthur L. Carter Journalism Institute at New York University. The thick atmosphere exerts an incredible amount of pressure on Gliese 1214b’s surface. Multi-color Transit Photometry of GJ 1214b through BJHK s Bands and a Long-term Monitoring of the Stellar Variability of GJ 1214. But if you go below that, you’ll probably start entering a much stranger world: a world of exotic ice. (In 2009, it was, in fact, only the second super-Earth to be discovered.). [8] It also shows a 1% intrinsic variability in the near-infrared probably caused by stellar spots. At its surface, Venus is 737 K, 462 °C, 867 °F. 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). According to NASA, there exists probable evidence of a great number of extraterrestrial oceans, which means there is a vast potential for…. The Shortest Distance Between You and Science, A project of NYU's Science, Health and Environmental Reporting Program. These aren’t like Earth. Gliese 1214 is a dim M4.5[4] red dwarf in the constellation Ophiuchus with an apparent magnitude of 14.7. Ice VII has actually been found to naturally occur in diamonds, and some scientists think it exists deep within Jupiter’s moon Europa. 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. Required fields are marked *, Distinguished Writer in Residence, New York University. “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. It is located at a distance of approximately 47 light years from Earth. 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. Habitability for humans: Not unless you like hot ice, In your childhood, you perhaps learned that about two-thirds of Earth’s surface is covered by water: not just the vast oceans, but ice caps and river systems and even the water vapor that dots the atmosphere in clouds. 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. As of 2015, GJ 1214 b is the most likely known candidate for being an ocean planet. (Scientists call this ice Ih.) 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 … 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. [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. GJ 1214 b juga dikenal sebagai Gliese 1214 b adalah bumi super luar surya yang mengorbit bintang GJ 1214.Planet ini ditemukan pada bulan November tahun 2009 dan berjarak sekitar 40 tahun cahaya dari Bumi.GJ 1214 b terletak di rasi bintang Ophiuchus dan merupakan planet luar surya kedua yang memiliki massa dan jari-jari lebih kecil daripada raksasa gas di Tata Surya. Gliese 1214 is a dim M4.5 red dwarf in the constellation Ophiuchus with an apparent magnitude of 14.7. 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. 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. It is located at a distance of approximately 47 light years from Earth. [3], No transit-time variations have yet been found for this transit. GJ 1214b is located in the constellation Ophiuchus, some 40 light-years from us. HD 80606 b 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. Distance from Earth: ~47 light-years Unlike terrestrial planets, the super-Earth doesn’t have a solid surface, making the height of the atmosphere difficult to define. 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. 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”). It helps that the planet is likely about the temperature of Mercury. Your email address will not be published. Credit: NASA, ESA, and D. Aguilar (Harvard-Smithsonian Center for Astrophysics). It is probably at least three billion years old and a member of the old disk. It is also believed that the temperature on the planet is so high that life may not exist on the planet. Gliese 1214 b may be rich in water, but this definitely is not the kind of water you'd want to be drinking!

A search for additional planets using transit timing variations was negative. Discovered in 2009, the planet is about 2.7 times Earth’s diameter and is almost 7 … If you were an extraterrestrial in a far distant star system looking back at the Earth with technology similar to ours, picking apart only the scantest details about distance from the Sun and surface temperature and atmospheric composition, you might reasonably think the entire planet is covered by water: that Earth is an ocean world. Earth is really a world of rock and metal that just happens to be painted over with a thin coat of water. It has a surface temperature of 120–282°C, and is a likely candidate for an ocean planet, meaning that it is probably completely covered with water (water can be liquid at these temperatures if the atmospheric pressure is high enough). Exotic Waters › Larger image GJ1214b, shown in this artist's view, is a super-Earth orbiting a red dwarf star 40 light-years from Earth. [12], The estimate for the stellar radius is 15% larger than predicted by theoretical models. “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. Gliese 1214 b (often shortened to GJ 1214 b) is an exoplanet that orbits the star Gliese 1214, and was discovered in December 2009. 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. Not only does this planet have a bone-crushing pressures with scorching hot temperatures, it has a deadly, dense ocean at the bottom of its atmosphere. Gliese 1132 b is too close to its star to be like Star Trek’s Class M planets — which generally looked like southern California from the surface. 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. [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. As of 2017, GJ 1214 b is the most likely known candidate for being an ocean planet. For that reason, scientists have nicknamed the planet "the waterworld". GJ 1214 B is known for being composed almost entirely of water, totaling approximately 75% of its mass while the other 25% is rock.

But what happens if GJ 1214 b is an ocean world — and if you start going deeper down? Go even deeper, and even with temperatures hot enough to melt metal you might find yourself in frozen clouds of ice X. Only a fraction of a percentage of Earth’s mass is actually water. It is also the first super-Earth around which an atmosphere has been found. At these high temperatures and high pressures, water cannot exist, on the surface, as a liquid. Its parent star is 42 light-years from the Sun, in the constellation Ophiuchus. Science, Health and Environmental Reporting Program 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. "At the bottom of the water-rich atmosphere of Gliese 1214 b, water should be a super-critical fluid." The star is about one-fifth the radius of the Sun with a surface temperature estimated to be 3000 K (2730 °C; 4940 °F). When you look at Earth from space, oceans dominate it. Its luminosity is only 0.33% that of the Sun. Gliese 1214 b is a large exoplanet 42 light years from Earth, it is a giant terrestrial planet, with its surface theoretically totally covered by water, being an ocean planet. Gliese 1214 is a dim M4.5 red dwarf in the constellation Ophiuchus with an apparent magnitude of 14.7. Your email address will not be published. Theme by Garrett Gardner. Living UFOs: Our Sky Is Their Ocean. [3] It is located at a distance of approximately 47 light years from Earth. Surface climate: Water is wet But astronomers believe there’s a different kind of ocean world orbiting other suns. GJ 1214b is 6 to 7 times larger than our earth. On Earth, the scale height is about 6 miles (10 kilometers), while on Gliese 1214 b it is three times deeper, according to Narita. Like other ocean planets, it has a surface that is extremely sensitive to the touch of anything, especially asteroids, which means it hates them. Mass: ~6.2 Earth masses "[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. 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. Scientists figure the top of Gliese 1132b’s atmosphere is around 533 K, 260 °Centigrade, 500 °Fahrenheit; probably hotter at the surface. No, these ocean worlds are more like very large comets, where the majority of the planet’s mass is water. New observations from NASA's Hubble Space Telescope show that it is a waterworld enshrouded by a thick, steamy atmosphere. 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. While this was cooler than the hot Jupiters that utterly dominated the lists of known exoplanets in 2009, it is still well more than warm enough to boil water. 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. Discovered by: David Charbonneau, et al. This ocean planet has a small amount of rockey surface in its core. [12] Its luminosity is only 0.33% that of the Sun. Eventually, you’ll hit a thick layer of liquid water. Six times as massive as Earth, Gliese 1214 b is less than three times as wide, falling between the Earth and the solar system's ice giants Uranus and Neptune in size. As such, if there’s water on the surface or even near the surface, it’s likely been vaporized. Now imagine the situation on Gliese 1214 b. Gliese 1214 b on the background of the parent star. GJ 1214b is classified as a water-world, and is the only example of such a planet yet to be discovered. [3] The star is rotating slowly, with a period that is most likely an integer multiple of 53 days. The thick layer of Ice VII that covers the core Size: ~2.7 Earth radii Its entire surface is a gigantic ocean, except in the poles, where the extreme cold temperatures made huge ice islands, some of them with frozen lakes and rivers. 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. Researchers believe that the surface of the planet is warming up at 200 ° C. The planet is literally an egg cooker! The planet orbits a small red dwarf star which has only 16% the mass of our own sun. Discovered by the MEarth project and investigated further by the HARPS spectrograph on ESO’s 3.6-metre telescope at La Silla, GJ1214b is the second super-Earth exoplanet for which astronomers have determined the mass and radius, giving vital clues about its structure. Gliese 1214 b (Often shortened to GJ 1214 b) is an exoplanet that orbits the star Gliese 1214, and was discovered in December 2009.
