GJ 1132:  Super Earth Discovery is Only 39 Light Years Away

Finding an atmosphere on an exoplanet is not new. But in general, the studied atmospheres are those of gaseous gases or “super-Earth” (rocky planets much bigger than our planet). Today, for the first time, the atmosphere of a planet similar to ours, small and telluric, has been studied: GJ 1132b.

An uncooperative ocean planet

GJ 1132b is a rocky planet located at 39 light years from here and which gravitates around the red dwarf Gliese 1132. It is 1.4 times bigger than Earth and weighs 1.6 times heavier. German scientists have managed to study its atmosphere using a Chilean telescope. To do so, they pointed the telescope in the direction of its star, waited for the moments when GJ 1132b passed by and used different filters to understand the composition of the atmosphere.

And what they found is amazing.

GJ 1132b has an atmosphere, which could be, according to scientists, saturated with water vapor or methane. Scientists then think that there is an ocean planet saturated with steam in the manner of a pressure cooker. Because the conditions on the ground of GJ 1132b seem unfit for life, the average temperature can be 370 degrees.

Nevertheless, this discovery is a big step in the hunt for life. Indeed, these scientists have managed to study the atmosphere of a small exoplanet located at light years from here and if GJ 1132b is not the promised paradise, the same technique could be used in the future on d Other promising stars. The search for the true twin sister of the Earth is still underway …
