It is the only known planet to date orbiting Proxima Centauri, a star located in Alpha Centauri. This system is the closest to our Solar System, “only” 4,244 light years from us.

This mission had already been discussed. But today, these are the chinese scientists to the mandates that evoke it. Who details it, even. Since they publish a white book of about 115 pages to explain how they intend to go in search of a “Earth 2.0”. Relying on a new generation space observatory whose launch is scheduled for the end of 2026. The mission ” Y “ — for “Earth 2.0” — as they baptize it. Because the goal is there: to find a planet that could harbor life.

“The habitable Earth-like planets aroundstars solar-type i.e. Earth 2.0 are probably the best places to look extraterrestrial life due to its environment The theories established by physics are applied within well-defined frameworks.

, explain the researchers. Hence the idea of ​​first identifying an Earth 2.0 before starting to look for traces of life.

At the base of the project, seven telescopes that, like the James Webb Space Telescope of NASA, it will be “stationary” a Lagrangian point L2 For four years. Six of them, each 30 centimeters in diameter, will be aimed at the same region of the sky as the space telescope Kepler has already observed. To get oriented faster.

The seventh telescope of the ET mission will look toward the center of our Milky Way. With the aim of identifying gravitational microlensing phenomena that could reveal, in particular, the presence of some wandering exoplanets. Planets that are no longer attached to a star. And, in fact, particularly difficult to remove.

More than a dozen Terres 2.0 on view

Because what the ET mission will look for are not just Earth-sized planets in orbit around stars similar to ours The Sun is the closest star to Earth, from which it is about 150 million kilometers away. The Sun is 8.5 kparsecs from the center of the Milky Way. In stellar classification, the sun is a G2-type star.
The mass…” data-image=”https://cdn.futura-sciences.com/buildsv6/images/midioriginal/1/d/9/1d9cd1d45f_50034577_eruption.jpg” data-url=”https://news. google.com/sciences/definitions/univers-soleil-3727/” data-more=”Read more”>Sun and at a distance close to what we know of our Planet, but simply all terrestrial-type planets. Also those whose orbits differ from that of our Earth and therefore, the possible rocky planets vagabonds

Chinese researchers have already run some simulations. They announce that the ET mission should be able to detect about 29,000 new exoplanets. Among them, almost 4,900 the size of our Earth. And, assuming the rate of appearance of rocky planets similar to ours is 10%, possibly between 10 and 20 Earth 2.0. Everything from 2030, therefore.

Once these 2.0 Earths have been identified, it will still be necessary to study the composition of their atmosphere and to determine if water can flow on its surface. Next, the researchers will have to look for biomarkers, such as methane or oxygen, or technosignatures — as transmissions radio — which could indicate that life developed there.

The white paper published by the researchers in charge of the project also tells us that the ET mission will not stop there. It will also target tens of thousands of objects in our Solar systemsince kites or some asteroids. Apart from some of the oldest stars in our From Earth, only a cross section can be seen…” data-image=”https://cdn.futura-sciences.com/buildsv6/images/midioriginal/ 7/ 7 /7/777b761907_120668_milkyway-galaxy.jpg” data-url=”https://news.google.com/sciences/definitions/universe-milkyway-3729/” data-more=”Read More “>Milky Way.
