English: Sodium in the atmosphere of the Hot Jupiter exoplanet of HD 209458, a 7th magnitude star, 150 light years away in the constellation Pegasus. Sodium filters out light from its parent star, and is detected using by analyzing absorption spectrum. Image Credit: A. Field, STScI
Astronomers using the orbiting Hubble Space Telescope have made the first direct detection and chemical analysis of the atmosphere of a planet outside our solar system. Their unique observations show it is possible to measure the chemical makeup of extra-solar planetary atmospheres -- and potentially to search for chemical markers of life far beyond Earth.
