10 new Earth-like planets have been discovered, out of 219 new cosmic objects. These 10 planets have the potential to support alien life.

At a press conference and on the official website, NASA presented new discoveries of possible life-saving planets in our galaxy. They are the Kepler’s telescope work, within the K2 mission, the most complete analysis of distant planets.

The totality of data collected by Kepler includes 4.034 objects, objects that are essential to find extraterrestrial life. Of all these objects, at least 90% are planets orbiting around a star at a distance at which life can develop.

“The data collected with the Kepler telescope is unique because it is the only one that contains a population of these terrestrial analogs – planets of the same size and orbit of the Earth. Understanding the frequency of these planets in the galaxy will help us develop future NASA missions “- Mario Perez, a scientist at this mission at the Astrophysics Division of NASA’s Science Mission Directorate

Natalie Batalha, a Kepler scientist, says there are two main types of small planets, which helps us understand the formation process. “These results will be the basis for future research of alien life.”

The Kepler Telescope has proven over time that nature prefers the small planets of two types: Rocky planets, like Earth and gaseous, like Neptune.

How Many Earth-Like Planets Are In The Galaxy?

“We like to say about this study that we can classify planets in the same way that biologists classify new species of animals. The discovery of two distinct groups of exoplanets is like discovering mammals and lizards belonging to distinct branches of the genealogical tree. “- Benjamin Fulton, California Institute of Technology.

It happens that more than half of the planets in our galaxy have no surface or are found under an extremely dense atmosphere. These types of planets cannot sustain any form of life.

Nature creates rocky planets 75% bigger than Terra, but these planets have a much lower amount of hydrogen and helium, a phenomenon that cannot yet be explained by the scientists.

The monitoring mission will end on September 30. The telescope is in good condition and until then it can still make new discoveries.

Up to now, 50 Earth-sized planets have been discovered and all are in the habitable area their star.

The mission will continue to collect data on and study a variety of other interesting astronomical objects.
