The newly discovered GJ 1132b another world is changing the game. According to astronomers, GJ 1132b is full of life because it has water and methane in the atmosphere.
Scientists are searching for extrasolar planets may be living as two new “Goldilocks” planets that have raised hope not only to finding alien life, but a similar planet like Earth. On one of these planets, astronomers assume that there is air.
Wolf 1061C is located about 14 light years from Earth and GJ 1132b, is about 39 light years from Earth quickly became two favorite exoplanets astronomers who are eager to find extraterrestrial life, and perhaps even the Earth branch.
Both of these distant worlds are in the Goldilocks zone of their star orbital -an area where it is neither too hot nor too cold for liquid water to exist.
Wolf 1061c is one of three planets orbiting M-Class red dwarf. Promising part is that this planet is so only in the center of habitable area. However, scientists warn that it is four times larger than our world, which means that it is highly unlikely that its gravity create a “runaway greenhouse effect” similar to our neighboring planet Venus.
On the other hand, GJ 1132b is a game changer. In fact, there are those who like stem on Earth. It has a diameter 50% larger than Earth and orbits its star in the warmer end of the Goldilocks zone. Given its size, it is very likely that there is a necessary condition for maintaining a “stable” atmosphere.
According to a recently published study in the astrophysical Journal , scientists at the European Southern Observatory in Chile – 16-member strong intergovernmental astronomy agency, GJ 1132b is proved that the planet is extremely promising because it has water and methane in the atmosphere.
Lead author astrophysicist John South worth told Scientific American: “We have shown that land-mass planet is capable of maintaining a dense atmosphere”.
“This is another step towards investigating whether a planet to host life.”
Discovering water on the planet is mind bending, finding methane is even more.
On Earth, 90% of all methane in the atmosphere is produced by living organisms known as methanogens-organisms that do not need oxygen and hydrogen rely on to survive
Researcher Julien de Wit added: “Detecting the atmosphere of Earth-sized planets around M-dwarfs is an essential step in the search for habitable exoplanets. The concern, however, is that they may not always be able to sustain an atmosphere because of the potential history of strong activity of their star.”
“Finding one with an atmosphere would provide us with hope.”
In the near future, bigger telescopes will allow us to capture higher resolution images of the light that passes through the planet’s atmosphere, which will help us detect –whit greater precision— its composition.
