| 説明 | This is an artist's impression of the Jupiter-size extrasolar planet HD 189733b being eclipsed by its parent star. The planet is a "hot Jupiter" that is so close to its star that it completes an orbit in only 2.2 days.Astronomers using the Hubble Space Telescope have measured carbon dioxide and carbon monoxide in the planet's atmosphere. To make this type of observation, astronomers subtract the light of the star alone from that of the star and planet together prior to eclipse. This allows astronomers to isolate the infrared emission of the planet and make spectroscopic observations that chemically analyze the day-side atmosphere.For more information, visit: hubblesite.org/contents/news-releases/2008/news-2008-41.htmlCredit: ESA, NASA, M.
