NASA got 4 times bigger ‘Earth’, will life be possible on another planet?

When it comes to the existence of life outside Earth, exoplanets appear as the biggest possible candidates. Planets that orbit stars other than the Sun are called exoplanets. Scientists have discovered many such exoplanets so far, which are rocky like Earth. Although detailed research did not show the possibility of life there, because the temperature of many planets is very high. Meanwhile, the US space agency NASA has discovered a new Earth-like planet. It is very far away in the outskirts of our galaxy. This new super Earth, named ‘Ross 508 b’, has raised the hopes of astronomers, because it is located in the habitable zone of its red dwarf star. The Subaru Telescope played a role in the discovery of this Earth-like planet. On which the planet was discovered using infrared spectrograph.

‘Ross 508 b’ is believed to be a potentially larger rocky world than Earth, but it is moving out of its habitable zone. Nevertheless, there is hope, because the planet retains water on its surface, which strengthens the possibility of life. NASA has reported that ‘Ross 508 b’ is a super Earth exoplanet. It orbits an M-type star, which is located about 37 light-years away from Earth. The mass of this planet is equal to that of 4 Earths and it takes 10.8 days for the planet to make one orbit around its star.

The question arises that how do scientists find those planets, which can be habitable. The answer is Goldilocks Zone. These are zones through which planets passing through may have the possibility of life. NASA has said that it is a planet that may be able to retain water on its surface and will be important for studying the possibility of life around M-class dwarf stars in the future.

A recent study has shown that liquid water can exist on the surface of exoplanets for many billions of years, even under different conditions. The role of liquid water is important in the search for exoplanets that can give life like Earth. Researchers from the University of Bern, the University of Zurich and the National Center for Competition in Research (NCCR) explain that this approach is desperately needed to search for habitable exoplanets.
