Current technology does not allow to determine the existence of life on its surface, despite some favorable planetary conditions.
Scientists at the Keck observatory, located near the Mauna Kea volcano dormant in the state & # 39; Hawaii, announced in the Journal Astronomy by the study & # 39; exoplanet images obtained in 2008, and technology analysis of the reflected light of that body, the atmospheric composition was determined.
The proportion of & # 39; gas is right to keep the hope that there was life on that planet, but other factors, such as temperature, come dance, that is still unknown.
The system & # 39; bodies that revolve around the star HR8799, located in the constellation & # 39; Pegasus, is composed mainly of four & # 39; giant planets, including HR8799c.
Dimitri MAWET, NASA astronomer and co-of detection author, explained that a combination of & # 39; adaptive optics was used in telescopes to correct the effect of illuminating the images produced by the Earth's atmosphere, along with & # 39 ; spectrometers – devices which analyze the composition of & # 39; light & # 39; high resolution.
"This type of & # 39; technology is exactly what we will use in the future to look for life signs on planets like Earth. We have yet to reach this goal, but we are going in & # 39; this direction, "stressed MAWET.
