They find a planet beyond the solar system that has water in the atmosphere



Astronomers at the US Observatory found that the giant planet HR8799c, 179 light-years from the solar system, has water and no methane in the atmosphere. Current technology does not allow to determine the existence of life on its surface despite some favorable planetary conditions.

Scientists at the Keck Observatory, near the inactive Mauna Kea volcano in Hawaii, reported in the Astronomical Diary that exploring the exoplanet images obtained in 2008 and the analytical technology of the light reflected by this body was certain composition of the atmosphere.

The proportion of the gases is favorable in order to keep the hope that the planet has life, but more factors such as temperature, dance, a fact that is still unknown.

The body system that rotates around the star HR8799, located in the Pegasus constellation, consists of four giant planets, among which HR8799c.

Dimitri Mawet, a NASA astronomer and co-author of the find, explained that a combination of adaptive optics is used in the telescopes to correct the effect of clouds generated by the earth's atmosphere along with a spectrometer "equipment that analyzes the composition of light" with high resolution.

"This type of technology is exactly what we will use in the future to look for signs of life on Earth-like planets." We have not yet achieved this goal, but we are going in that direction, "said Mawett.
