According to the British "Daily Mail" reported on November 23, astronomers made new breakthroughs in the search for extraterrestrial life and found that there is water in the atmosphere of the HR 8799c planet 179 light years away from the earth but lacking methane.
An astronomical group observed at the Keck Observatory in Mauna Kea, Hawaii, gas planet HR 8799c has water in the atmosphere but lacks methane.
The planet is located in Sagittarius. It is one of four planets that connect the stellar HR 8799. It is seven times as big as Jupiter and 179 light years from the earth.
Astronomers used high-tech instruments to confirm the presence of water in the planet's atmosphere and the lack of methane. The team combined high resolution spectroscopy and adaptive optics to avoid the unambiguousness of the Earth's atmosphere, capture images of the planet and use a spectrometer to decompose the planet's light to get a fingerprints of the chemical in the atmosphere.
Although astronomers have taken photos of more than a dozen foreign planets, HR 8799 is the only multiplayer system that has been photographed so far. Experts now want to repeat this process for asteroids closer to their stars.
The goal of Keck Observatory scientists is to look for chemicals suitable for life, such as water, oxygen and methane, in the atmosphere of ground planets. This goal can be achieved through a 30 meter telescope that will be put into service.
