NASA discovered a planet 260 light years away atmospheric water vapor distribution

NASA’s Hubble Space Telescope observations using WASP-43b exoplanet atmospheric scientists to track the distribution of water vapor at different heights.


NASA to draw water vapor distribution exoplanet WASP-43b in different seasons, planet orbital period of only 19 hours

Foreign media reports, NASA spent on the Hubble Space Telescope exoplanet WASP-43b were observed, which is an environment with extreme exoplanet surface temperature can reach 3,000 degrees Fahrenheit, hot enough to melt some of the world’s steel, The side facing away from the star is a relatively cold world, temperatures can fall below 1000 degrees Fahrenheit, equivalent to 537 degrees Celsius. WASP-43b is located 260 light-years exoplanets outside, was discovered in 2011. Scientists found that often bathed in the light of the stars among the transit phenomenon makes exoplanet discovered by us. Now, we get the exoplanet WASP-43b atmospheric data, tracking the distribution of water vapor at different heights.

From the University of Chicago team leader Jacob Bean believe that these observations open up new ways to detect different types of exoplanets nature, WASP-43b exoplanet is a typical hell world, one side is very hot environment, the other side of the temperature difference is great, so exoplanet has a very severe atmospheric circulation, so if we draw a kinetic model of the planet, the study of exoplanets is very helpful. WASP-43b fastened volume extrasolar planets and the solar system Jupiter quite, but the density has reached around Jupiter twice, the system will also have a orange dwarf star, WASP-43b-based orbital radius of the outer planets are very close to the Fengyun primary star.

It is noteworthy, WASP-43b’s orbital period of only 19 hours, the planet is tidally locked, so there is always a hemisphere facing the star, which resulted in one side is hot as hell, the other side is relatively low in the world It’s like we have one side always facing the moon like the Earth. Through this observation, astronomers first observed detailed atmospheric stratification exoplanets, scientists also use the technique to study the unprecedented WASP-43b planet’s atmosphere, spectral analysis can be exoplanet albedo light into we know lines to determine the moisture content of the planet and atmospheric temperature.

Meanwhile, scientists can accurately measure the water vapor distribution on different longitude exoplanet planet’s rotation through research. Exoplanet WASP-43b is a hot Jupiter, orbit radius is very small, there is no such planets in the solar system, it is interesting that this type of planets outside the solar system are very common, the University of Chicago team members Laura think WASP-43b extremely high temperatures, all the moisture evaporates in the atmosphere, rather than condensed into icy clouds, but some of the hot Jupiter’s upper atmosphere on the ice substance can be locked, which comes mainly from the early comet impact.
