He goes on to say that the earth has seen good days.
So, if you are fed up with the drama of climate change, presidential elections and the constant dangers of nuclear war, there may be about 300 million other options for building a home, according to new data eroded by the nation. Kepler Space Telescope of Aeronautics and Space Administration.
Between 2009 and 2018, Kepler explored the far reaches of our galaxy in search of exoplanets. In particular, rock-based, Earth-sized planets that orbit our Sun-like star and orbit at approximately equal distances. Kepler’s tour revealed billions of possible galaxies outside our solar system. It also delivered images of other blue-green planets with the potential to support life.
Now, an updated analysis of the findings of the retired telescope, published in the Astronomical Journal, provides a more accurate snapshot of the habitable world. In a “consonant” estimate, NASA researchers believe that at least 50% of all stars like the Sun have terrestrial planets with water potential. More optimistic models dello predict up to 75%.
“Kepler has already told us there were billions of planets, but now we know that a good portion of those planets could be rocky and habitable,” said lead study author Steve Bryson in a statement on the NASA site. “Although this result is far from the ultimate value, and the water on the planet’s surface is just one of the many factors supporting life, it is very exciting that we calculated. [that] This is common in this world with such high confidence and accuracy. “
Their aim in this study was to establish a more complete equation to determine the habitation, by examining the relationship between the distance of the exoplanet and the temperature of its parent star, as well as the amount of light energy radiation that the star emits.
The data was the key to the European Space Agency’s Gaia mission.
Co-author Ravi Koparapu said, “We always defined habitat in terms of the physical distance of the planet from the star, so that it is not too hot or cold, so we left a lot of assumptions.” “Gaia’s data on stars allowed us to see these planets and their stars in a whole new way.”
Koparapu said, “Not every star is the same. “And neither is every planet.”
New calculations suggest that there are at least four habitable planets at relatively close distances from Earth, between 20 and 30 light-years – not considered human, unreliable, but scientifically meaningful.
Co-author Michelle Kunimoto said it is invaluable to know how common the different types of planets are for the formation of the next Explanet-searching mission.
The more accurately they can point to these highly deserving worlds, the more successful the exploration of exoplanets can be. And if we ever hope to get out we will need that data.
“Surveys considering smaller, potentially habitable planets around stars like the Sun will be based on results like these to increase their chances of success.”
