Hubble finds carbon dioxide in the planet extrassolar
Wednesday, December 10th, 2008Although the fame of carbon dioxide (CO2) does not walk very good here on Earth, it is good to remember that this is a gas essential to life. At least the forms of life on Earth.
Hence the importance of finding that has been done through images taken by the Hubble Space Telescope, the researchers found carbon dioxide in the atmosphere of a planet orbiting a star other than the sun, a so-called planet extrassolar.
Life outside Earth
The planet is HD 189733 b, the size of Jupiter and too hot to support life - always in the definition of terrestrial life. But Hubble’s observations are a proof that the basic chemistry of life can be detected in very distant planets, orbiting other stars.
The organic compounds - such as CO2 - can also be a by-product of processes of life. Scientists hope a day detect its presence in a planet extrassolar more like the Earth, in what could be the first direct evidence of the existence of life beyond our planet.
Previous Hubble observations made by the Spitzer telescope on the same planet HD 189733 b already had detected water vapor. Earlier this year, the Hubble found methane in the atmosphere of the planet.
New frontier of science
“The Hubble was designed primarily for observations of the distant universe and yet he is opening a new era of research in astrophysics and science compared to the planets,” says scientist Eric Smith, the team’s space telescope.
“These studies begin to determine the atmospheric composition and the chemical processes underway in distant worlds orbiting other stars. The future of this new frontier of science recently opened is extremely promising, since we expect discover many other molecules in atmospheres of exoplanets,” concluded the scientist.
