Scientists have revealed on Wednesday that water was first found to support life in an alien planet's atmosphere with Earth-like temperatures.<\/p>\n

K2-18b orbits eight times as large as the Earth's mass in the "residentable zone" of the star at a distance too far or too close to the distance water can exist in the form of liquids have been reported in the journal Nature Astronomy.<\/p>\n

Astronomer Giovanna Tinetti of University College London told AFP that "the planet is the best candidate outside our solar system," looking for signs of life.<\/p>\n

"We can't assume that there's sea on the surface, but that's a real possibility." <\/p>\n

Of the more than 4,000 alien planets to date, it is known to combine the most rocky surfaces and atmosphere with water.<\/p>\n

Most alien planets with the atmosphere are giant gas balls, and the few rocky planets with data available seem to have no atmosphere at all.<\/p>\n

Even if they do, most Earth-like planets are too far from the star to have liquid water or so close that H2O does not evaporate.<\/p>\n

Found in 2015, the K2-18b is one of hundreds of so-called "Super-Earths" discovered by NASA's Kepler spacecraft. <\/p>\n

Future space missions are expected to detect hundreds more in the coming decades.<\/p>\n

& # 39; Earth is unique? & # 39;<\/strong><\/p>\n

Angels Tsiaras, head of UCL, said, \u201cIt's exciting to find water in an inhabitable world outside the Earth.<\/p>\n

"K2-18b is not & # 39; Earth 2.0 & # 39;" "But it is closer to our answer to the fundamental question. Is the Earth unique?"<\/p>\n

Tsiaras and his team worked with spectral data captured in 2016 and 2017 with the Hubble Space Telescope, using open source algorithms to analyze starlight filtered through the atmosphere of K2-18b. <\/p>\n

They must have found a symbol of water vapor. Exactly how uncertain, but computer modeling suggested concentrations between 0.1 and 50{7be40b84a6a43fc4fae13304fce9a2695859798abfc41afd127b9f8b21c5f9c5}. <\/p>\n

By comparison, the rate of water vapor in the Earth's atmosphere is between 0.2{7be40b84a6a43fc4fae13304fce9a2695859798abfc41afd127b9f8b21c5f9c5} above the poles and up to 4{7be40b84a6a43fc4fae13304fce9a2695859798abfc41afd127b9f8b21c5f9c5} in the tropics.<\/p>\n

There was also evidence of hydrogen and helium. According to the study, nitrogen and methane may also be present but cannot be detected with current technology.<\/p>\n

Further research allows you to determine the cloud coverage and the proportion of water in the atmosphere.<\/p>\n

First of many <\/strong><\/p>\n

Water is important for finding life because it partially carries oxygen.<\/p>\n

"Life as we know it is based on water," Tinetti said. <\/p>\n

K2-18b orbits a red dwarf star about one hundred billion kilometers away from the Leo constellation of the Milky Way, and is probably hit by more destructive radiation than Earth.<\/p>\n

"This is likely the first of many discoveries about potentially inhabitable planets," said co-author UCL astronomer Ingo Waldmann. <\/p>\n

"Because the super-earth like the K2-18b is not only the most common planet in our galaxy, but also the red dwarf star, which is a smaller star than the sun, is the most common star."<\/p>\n

The next generation space-based star gaze tool, led by the James Webb Space Telescope and the European Space Agency's ARIEL mission, can depict alien planets in greater detail. <\/p>\n

Scheduled for release in 2028, ARIEL will survey approximately 1,000 planets and perform a sampling large enough to find patterns and identify outliers.<\/p>\n

"More than 4,000 extraterrestrial planets have been discovered," said Tinneti, "but we don't know much about their composition and properties. "By observing large quantities of planetary samples, we hope to reveal the secrets of their chemistry, formation and evolution."<\/p>\n
