NASA found 4 times the size of ‘Earth’, is life possible on another planet?

When it comes to the existence of life outside of Earth, exoplanets appear as the most likely candidates. Planets that orbit stars other than the Sun are called exoplanets. Scientists have so far discovered several exoplanets that are rocky like Earth. Although detailed research has not shown the possibility of life there because the temperature of many planets is too high. Meanwhile, the American space agency NASA has discovered a new planet like Earth. It is far, far on the outskirts of our galaxy. This new super-Earth named ‘Ross 508 b’ has raised the hopes of astronomers, as it lies 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 an infrared spectrograph.

‘Ross 508 b’ is thought to be a possibly 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 reported that ‘Ross 508 b’ is a super-Earth exoplanet. It orbits an M-type star, located about 37 light-years from Earth. The mass of this planet is equal to 4 Earths and it takes 10.8 days for the planet to complete one orbit around its star.

The question arises as to how scientists find these planets, which may be habitable. The answer is the Goldilocks Zone. These are the zones through which life may be possible in transiting planets. NASA has said that this 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 revealed that liquid water can exist on the surface of planets for billions of years even under different conditions. The role of liquid water is important in the search for planets that could support Earth-like life. Researchers from the University of Bern, the University of Zurich and the National Center for Competition in Research (NCCR) point out that this approach is urgently needed in the search for habitable planets.
