For the first time, astronomers have spotted water vapor in the atmosphere of a viable planet, thus opening a new search page for indicators of life outside the system. solar.
Located in the constellation Leo, 1102 light years from the solar system, Kai2-18Bi is twice as large as the Earth and is probably composed of silicates (such as Earth, Mars, Venus) and ice.
The data collected by the Hubble Space Telescope showed that the planet had a water vapor atmosphere, said Jovana Tenetti, co-author of the study published in the journal Nature Astronomy.
Based on data collected by Hubble in 2016 and 2017, researchers have developed algorithms to analyze light passing through the atmosphere. The results revealed the partial imprint of the water vapor.
The planet and its small red star, Kai-18-18, are located in the middle region of the heat source, in an ideal location to form liquid water and to allow life to develop in the known way .
