Hubble Spots CO2 on Extrasolar Planet

Add carbon dioxide to the atmospheric brew enveloping a Jupiter-sized planet orbiting a star about 65 light-years from Earth.

Hubble Spots CO2 on Extrasolar Planet

The finding, made by astronomers using an infrared sensor on the Hubble Space Telescope, doesn’t do anything to improve the odds of finding life on HD 189733, which also contains methane, carbon monoxide and water in its atmosphere.

Hubble Finds Carbon Dioxide on an Extrasolar Planet

NASA’s Hubble Space Telescope has discovered carbon dioxide in the atmosphere of a planet orbiting another star. This is an important step along the trail of finding the chemical biotracers of extraterrestrial life as we know it.

Hubble Finds Carbon Dioxide on an Extrasolar Planet

The Jupiter-sized planet, called HD 189733b, is too hot for life. But the Hubble observations are a proof-of-concept demonstration that the basic chemistry for life can be measured on planets orbiting other stars. Organic compounds can also be a by-product of life processes, and their detection on an Earth-like planet may someday provide the first evidence of life beyond Earth.

Previous observations of HD 189733b by Hubble and the Spitzer Space Telescope found water vapor. Earlier this year, Hubble astronomers reported that they found methane in the planet’s atmosphere.
