To obtain the spectra, astronomers used the NASA/ESA Hubble Space Telescope to collect light from TRAPPIST-1 passing through the exoplanets’ atmospheres as the exoplanets crossed in front of the star. The purple curves show the predicted signatures of gases such as water and methane that absorb certain wavelengths of light. These gases would be found in a puffy hydrogen-dominated atmosphere similar to those of gaseous planets such as Neptune. The Hubble results, indicated by the green crosses, reveal no evidence of an extended atmosphere in three of the exoplanets (TRAPPIST-1d, f, and e). Additional observations are needed to rule out a hydrogen-dominated atmosphere for the fourth planet (TRAPPIST-1g). The evidence indicates that the atmospheres are more compact than could be measured by the Hubble observations.https://stellarplanet.org/wp-content/uploads/2018/03/heic1804b_1280.jpgComprehensive Spectrum of WASP-39bUsing the NASA/ESA Hubble Space Telescopes as well as data gathered by other telescopes in space and on the ground astronomers have analysed the atmosphere of the exoplanet WASP-39b. It is the most complete spectrum of an exoplanet’s atmosphere possible with present-day technology. By dissecting starlight filtering through the planet’s atmosphere into its component colours, the team found clear evidence for water vapour. Although the researchers predicted they would see water, they were surprised by how much water they found — three times as much as Saturn has. This suggests that the planet formed farther out from the star, where it was bombarded by icy material.https://stellarplanet.org/wp-content/uploads/2018/03/wasp39b1.pngWASP39b1https://stellarplanet.org/wp-content/uploads/2018/03/heic1804a.jpgWasp-39b and its parent star (artist’s impression)A team of British and American astronomers used data from several telescopes on the ground and in space — among them the NASA/ESA Hubble Space Telescope — to study the atmosphere of the hot, bloated, Saturn-mass exoplanet WASP-39b, about 700 light-years from Earth. The analysis of the spectrum showed a large amount of water in the exoplanet’s atmosphere — three times more than in Saturn’s atmosphere. WASP-39b is eight times closer to its parent star, WASP-39, than Mercury is to the Sun and it takes only four days to complete an orbit.2018-03-02T20:44:49+00:00weekly0.6https://stellarplanet.org/2017/11/30/wasp-39b/2017-11-30T14:14:32+00:00monthlyhttps://stellarplanet.org/media/kevin-anderton-infographics/https://stellarplanet.org/wp-content/uploads/2017/11/kevin_anderton.pngkevin_andertonhttps://stellarplanet.org/wp-content/uploads/2017/11/hat-p-26b_final_small.jpgHAT-P-26b2017-11-29T21:24:00+00:00weekly0.6https://stellarplanet.org/media/card-sets/https://stellarplanet.org/wp-content/uploads/2017/11/cards.pngcards2017-11-27T22:59:35+00:00weekly0.6https://stellarplanet.org/media/audio/https://stellarplanet.org/wp-content/uploads/2017/11/1545765_497954880323840_345450582_n.png1545765_497954880323840_345450582_nhttps://stellarplanet.org/wp-content/uploads/2017/11/12998731_1787831294785617_5460328376756944124_n.jpg12998731_1787831294785617_5460328376756944124_nhttps://stellarplanet.org/wp-content/uploads/2017/11/11005799_805569122846320_1601924281_n-e1511804058355.jpgHannah at the microphone2017-11-27T20:22:30+00:00weekly0.6https://stellarplanet.org/posts/2017-11-27T00:41:40+00:00weekly0.6https://stellarplanet.orgdaily1.02025-05-20T14:20:14+00:00
