30 percent of the planets in the Milky Way may be habitable for life

 Millions of planets orbiting yellow dwarfs could hold the key to the discovery of extraterrestrial life. A recent study by astronomers from the University of Florida (USA) and published in the journal Proceedings of the National Academy of Sciences showed that about a third of the studied planets could be habitable.

Yellow dwarfs, including our sun, are rare in the Milky Way, which is dominated by cooler, smaller stars. However, despite this, millions of planets revolve around yellow dwarfs, some of which are close enough to their stars to support life.

However, life on these planets faces many threats. Being close to their stars exposes planets to deadly radiation and gravitational forces capable of tearing the planet apart.

The researchers measured the orbital eccentricity of more than 150 planets detected by the Kepler telescope and orbiting dwarf stars. They found that planets with more rounded orbits are more likely to retain water on their surfaces, which is an important factor in the possibility of life....<<<Read More>>>...
