… A 63 años luz de distancia se encuentra el exoplaneta HD 189733b, de color azul celeste, según acaba de confirmar un equipo de astrónomos. Earth's blue atmosphere plus the blue tint of the oceans dominate our world's hue. Context. Observations suggest that exoplanets such as HD 189733b form clouds in their atmospheres which have a strong feedback onto their thermodynamical and chemical structure, and overall appearance. One side always faces the star and the other side is always dark. HD 189733b's deep blue colour is produced by silicate droplets, which scatter blue light in the scorching atmosphere. The deep blue color of HD 189733b: albedo measurements with HST/STIS at visible wavelengths T. M. Evans1 , F. Pont2 , D. K. Sing2 , S. Aigrain1 , J. K. Barstow… Earth's blue atmosphere plus the blue tint of … Due to its size and compact orbit, HD 189733b is one of the most studied extrasolar planets. With the exception of Mars, the colours are primarily determined by the chemistry of the planets' atmospheres. The Spitzer telescope has managed to track HD 189733b for a full 2.2 day orbit (it was blocked by its star for some of that but nevermind that) and has built a detailed spectral map of the entire planet, showing exactly what temperature it is.

See how the Hubble Telescope did it. Given that this system has the same visual magnitude as HD 209458, it promises much for the study of close transiting extrasolar planets.
Figure 3 shows an RGB colour estimation for HD 189733b clouds by interpolating the light scattering result. The individual cloud results for HD 189733b and HD 209458b allow to understand the difficulty in detecting molecular water on HD 209458b: The H 2 O content at 0.1 bar is higher on HD 189733b then in HD 209458b. We further found that the clouds on the hot Jupiter HD 189733b reflected more efficiently in blue than red spectral range. HD 189733b … In order to measure what this planet would look like to our eyes, the astronomers measured how much light was reflected off the surface of HD 189733b … By observing this planet before, during, and after it disappeared behind its host star during orbit, astronomers were able to deduce that HD 189733b is a deep, azure blue - reminiscent of Earth's colour as seen from space.

This plot compares the colors of solar system planets to the color of the hot-Jupiter-class planet HD 189733b. Astron. HD 189733b is a Jupiter-sized extrasolar planet orbiting a yellow dwarf star that is in a binary system called HD 189733 in the constellation of Vulpecula, near … Last Update: 1 September 2019 7-Jun-2020 03:19 UT

HD 189733b’s colour is probably due to other substances. With the exception of Mars, the colors are primarily determined by the chemistry of the planets' atmospheres. HD 189733, also catalogued as V452 Vulpeculae, is a binary star system approximately 64.5 light-years away in the constellation of Vulpecula (the Fox).The primary star is suspected to be an orange dwarf star, while the secondary star is a red dwarf star. HD 189733b is a Jupiter-sized extrasolar planet orbiting a yellow dwarf star. This artist's concept shows exoplanet HD 189733b orbiting its yellow-orange star, HD 189733. & Astrophys., 533, A50 paper arxiv Planet HD 189733b lies some 63 light years beyond our Solar System in the constellation Vulpecula is a deep cobalt blue according to data gathered …
