The atmosphere was discovered 39 light-years from the exoplanet GJ1132b.

An Earth-sized rocky planet orbiting a dim star may be shrouded in a hazy atmosphere 39 light-years away, suggesting there is a "water world," an international team of astronomy researchers said in an article published on the New Scientist website.
is the first time astronomers have found an atmosphere on an exoplanet the size and mass of Earth, and an important step on the road to finding extraterrestary life.
exoplanet, called GJ1132b, is a small "super-Earth" with a measured radius of 1.4 times that of Earth and a mass of 1.6 times that of Earth. Using the European Southern Observatory's 2.2-meter ESO/MPG telescope in Chile, the
team observed it from seven different bands and found that it appeared larger and more hazy than other wavelengths in observations at a particular wavelength, suggesting that the planet had an atmosphere at which the wavelength could not penetrate.
team at the University of Cambridge and the Max Planck Institute for Astronomy simulated a series of possible atmospheric models and found that atmospheric models rich in water or methane could better explain observed hazy phenomena.
GJ1132b is much hotter than Earth, suggesting it could be a "water world" with a hot steam atmosphere.
a year ago, astronomers first detected the atmosphere on a super-Earth called Cancer 55e, but the exoplanet is much larger than Earth, about eight times the mass of Earth.
the chemical composition of exoplanets' atmospheres may help in the search for extraterr earth life, the Report said.
Sara Sage of the Massachusetts Institute of Technology compiled a list of 14,000 different molecules that provide "coordinates" of life features for the search for the alien world, including key components such as ozone and methane.
NASA's James Webb Space Telescope (JWST), scheduled for launch next year, will be a successor to the Hubble Space Telescope and will have the capability to conduct atmospheric research on exoplanets;
the importance of the atmosphere and water to life is self-evident.
Earth's atmosphere blesses all forms of life, and you and I live in the world today.
look at our immediate neighbor, Mars, an Earth-like planet that has been stripped of its atmosphere by the solar wind and has evaporated most of its water, and is now deserted.
, the atmosphere and water as clues to the search for extraterriter life, is by no means a scientist "shooting the brain."
, however, there are thousands of Earth-like planets being searched, how many of which are truly comparable to Earth? On the day the answer is revealed, humanity will have to re-examine itself.
