In search & # 39; vital signs: verify exoplanet has water in its atmosphere



Team & # 39; researchers found that HR 8799c, gas giant b & # 39; & # 39 bulk seven; times that & # 39; Jupiter, has water in its atmosphere, an indication of the presence of life.

The researchers, who obtained with the help date & # 39; the Keck Observatory in & # 39; Mauna Kea in & # 39; Hahwajja (USA), used spectroscopy b & # 39; high resolution with a method called "optical adaptive "to" correct the distortive effect of & # 39; World ", according to the study published 20 & # 39; November in the journal the Astronomical Journal. The results of his work show that the exoplanet is water, while the presence of methane has not been confirmed.

"This type of & # 39; technology is exactly what we use in the future to look for life signs on planets like Earth, but we are still on the road," said Dimitri MAWET, professor of astronomy at the Institute . Technology from California (USA), quoted in & # 39; a statement on the website of the observatory.

It is reported that the direct image of the planet HR8799, obtained in the framework of & # 39; that study, are the first pictures & # 39; this type of & # 39; planetary system that orbit stars other than the Sun.

The experts will continue to work in & # 39; this area and will also study other small planets are closer to their stars. The specialists state that the main objective of the research is to find biomarker, including water, oxygen and methane, which can show the presence of life on her face.
