Astronomers have discovered that a so-called "hot Jupiter" found 63 light-years from Earth has both water vapor and carbon dioxide in its atmosphere. Though scientists already knew that water vapor was present in the planet’s atmosphere, they only recently detected the carbon dioxide. HD 189733b has a fiery(火の、燃えさかる), molten(熱で溶けた)core and a highly gaseous atmosphere that mimics the atmosphere found on Jupiter, but with surface temperatures of about 1,800°F (1,000°C), it is too hot to support life. Despite this, astronomers believe that these observations demonstrate that the basic chemistry for life can be found on planets orbiting other stars.
