According to the British "Daily Mail" reported on November 23, astronomers have made new developments in search of extraterrestrial life, and water was found in the atmosphere of the AD 8799c planet 179 light years away from Earth, but she does not have methane.
An astronomical group observed at the Keck Observatory in Mauna Kea, Hawaii, that the gas planet HR 8799c has water in the atmosphere but does not have methane.
The planet is located in Sagittarius. One of the four planets covered by the HR 8799 is aimed at. There are seven times as large as Jiwpiter and 179 light years of Earth.
Servers used high-tech instruments to confirm the presence of water in the atmosphere of the planet and the lack of methane. The team combined a high resolution spectroscopy and adaptive optics to avoid the ambiguity of Earth's atmosphere, take pictures of the planet, and use a spectrometer to decompose the light of the planet to get the fingerprints of the chemical in the atmosphere.
Although serpentists have taken pictures of more than a dozen foreign planets, HR 8799 is the only multi-planetary solar system designed to date. Experts now want to repeat this process for asteroids closer to their stars.
Scientists aim at Keck Observatory to look for vitamins that are suitable for life, such as water, oxygen and methane, in a terrestrial planet atmosphere. This aim can be achieved through a 30 meter telescope that will be used.
