The HS finds the water vapor in the atmosphere of the Beastie zone export

The Hubble Space Telescope is seen as the signature of water vapor in super-Earth environments, in its host star's habitat where water can be found in liquid form, which is known on Earth. General Chat Chat Lounge

Known as K2-18b, this aspect is located about 110 years from Earth, in which a red star in the Neil-Leo is red. While it is located in the area of ​​the star's residence, it is exposed to a much higher level of radiation from the Earth than from the Earth.

Even so, "finding water on a potentially reliable world without Earth is incredibly exciting". University College College of London's Center for Space Exomist Information of Enzos Stairs and " The center of natureGeneral Chat Chat Lounge "K2-18b is not & # 39; Earth 2.0 & # 39; not because it is specially designed for very large and varied environments. However, it leaves us with the answer to the fundamental question: is Earth unique. is the? "

Using data collected by Hubble in 2016 and 2017, researchers were developing algorithms to analyze the light of a metal star that passed through a water pathway to the environment of K2-18b, which is water vapor, hydrogen and helium. Indicates the landmarks. Researchers believe other molecules, including nitrogen and fish, are likely but out of the reach of current technology.

First-generation space telescopes, however, will be equipped with more sensitive devices, including NASA's James Webb Space Telescope and AS's Wesmotic Remote-Sensing Inspired Airplane Large Survey – RIL missions, which provide much more detailed information on astronomers exoplanet inventions. Allows the collection of data.

"Our discovery makes Cake 18-B one of the most exciting targets for future studies," said Giovanna Tinley, co-author of UCL / CSD and principal investigator at RIEL. "More than 4,000 implants have been discovered but we do not know much about their composition and nature. Looking at the large size of the planets, we hope to reveal secrets about their chemistry, formation and evolution."
