Scientists Found Atmosphere Around Earth-Like Planet For The First Time


For the first time, scientists have discovered the Earth-like planet named GJ 1132b that is 39 light years away. This could give a new way towards the discovering new life on the far side of our solar system. A team of researchers from Keele University in the U.K. made use of ESO/MPG telescope in Chile to gather the images of the planet’s host star, GJ 1132. Scientists claim that there might be more planets with the environment in which life can survive. The planet is significantly hotter and 1.4 times larger than Earth, so there could be the existence of a ‘water world’ with an atmosphere of hot steam. There was a slight decrease in the brightness of the planet as it passed in front of a cool host star absorbing the star’s light.

“With this initial research, we have taken the first probationary step into finding the atmosphere of smaller and lower mass planets”, researchers said. GJ 1132b is known as transiting planet. When observed form the surface of the Earth, it directly passes in front of its star every 1.6 days and blocks some of the star’s light. In comparison with the other planets, GJ 1132b is larger at one of the infrared wavelengths. The study reveals that this atmosphere is cloudy to this particular infrared light but crystal clear to all others.

According to the research team, GJ 1132b planet would prove the base for the further study of space research facilities such as the Hubble Space Telescope and the ESO’s Very Large Telescope. Studying the chemical composition of exoplanet atmospheres could help in finding the life on any planet. Oxygen released from plants help in the creation of ozone layer and methane is the outcome of the volcanic activity. Both of them act like an atmospheric life marker.
