NASA: There are at least 300 million habitable planets

According to research using data from NASA’s Kepler Telescope, around 300 million exoplanets may have water.

Ever since astronomers confirmed the presence of planets outside of our solar system, also known as exoplanets, humanity has wondered how many of these planets might have. life.

Now we are getting closer to the answer. According to new research results published by scientists at NASA in The Astronomical Journal, our galaxy is estimated to have at least 300 million habitable planets. Some exoplanets may even be our interstellar “neighbors”, with at least four planets within 30 light years of the Sun and the closest perhaps at 20. light.

This figure is based on conservative estimates by researchers that 7% of stars similar to the Sun could have life. However, if the average wait rate is 50%, the number could be higher.

This research helps us understand the potential of these planets to have survival factors. It is an essential part of astrological biology, the study of the origin and future of life in the universe.

The study was carried out by researchers at NASA and based on data from the Kepler Telescope mission. NASA shut down this space telescope in 2018 after running out of fuel. Nine years of telescope observations reveal that there are billions of planets in our galaxy.

Steve Bryson of NASA, lead author of the study, said: “Kepler told us there are billions of planets, but now we know that some of them can be rocky, containing water. . in surface and habitable. Although this result is far from the final number and the water on the planet’s surface is only one of the many factors supporting life, it is interesting to calculate these planets with degrees of magnitude. such precision “.
