HD 189733b's deep blue colour is produced by silicate droplets, which scatter blue light in the scorching atmosphere.

This suggests that the clouds on this planet will appear midnight blue in colour if viewed with human eyes. But that's where the similarities end. With the exception of Mars, the colours are primarily determined by the chemistry of the planets' atmospheres.

One side always faces the star and the other side is always dark. NASA's Hubble Space Telescope measured the …

HD 189733b’s colour is probably due to other substances. This artist's concept shows exoplanet HD 189733b orbiting its yellow-orange star, HD 189733. Earth's blue atmosphere plus the blue tint of … GMRT search for 150 MHz radio emission from the transiting extrasolar planets HD 189733 b and HD 209458 b 2011 LECAVELIER des ETANGS A., SIROTHIA S., GOPAL-KRISHNA & ZARKA Ph. The Color of HD 189733b Compared to Our Solar System NASA, ESA, and A. Feild (STScI/AURA) This plot compares the colors of solar system planets to the color of the hot Jupiter HD 189733b. For the first time, scientists have captured the visible color of an alien planet, called HD 189733b, 63 light-years from Earth. 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. & Astrophys., 533, A50 paper arxiv With the exception of Mars, the colours are primarily determined by the chemistry of the planets' atmospheres.

HD 189733b is the first exoplanet caught passing in front of its parent star in X-rays. True colour of exoplanet measured for the first time by ESA/Hubble Information Centre This illustration shows HD 189733b, a huge gas giant that orbits very close to its host star HD 189733.

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… Read more: 1.usa.gov/1dnDZPu . Aims: Inspired by mineral cloud modelling efforts for brown dwarf atmospheres, we present the first spatially varying kinetic cloud model structures for HD 189733b. Earth's blue atmosphere plus the blue tint of the oceans dominate our world's hue. HD 189733b is a Jupiter-sized extrasolar planet orbiting a yellow dwarf star.

HD 189733b is a gas-giant slightly larger than Jupiter located 370 trillion miles (600 trillion km) from Earth - or 63 light-years.

Due to its size and compact orbit, HD 189733b is one of the most studied extrasolar planets. 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. 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

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.
