[EN VIDÉO] Proxima b, the closest exoplanet to us!
It is the only known planet to date that orbits Proxima Centauri, a star located on Alpha Centauri. This system is the closest to our Solar System, “only” 4,244 light-years from us.

This mission has already been mentioned. But now, these are Chinese scientists of the commands that arouse it. Who details it, though. Since they published a white paper of about 115 pages to explain how they intended to find and a “Earth 2.0”. By relying on a new generation space observatory whose launch is scheduled for the end of 2026. The mission “UG” – for “Earth 2.0” – while they were baptizing it. Because the goal is there: to find one planet that can be home to life.

“It’s like the Earth inhabiting the planets aroundstar of the solar type, i.e. Earth 2.0, is probably the best place to look extraterrestrial life because of their environment physicallychemical and possibly biological similar to Earth ”, explain the researchers. That’s why the idea of ​​first identifying an Earth 2.0 before starting to search for signs of life.

At the base of the project, seven telescopes, such as James Webb Space Telescope from NASA, may be “stopped” on Lagrange point L2 for four years. Six of these – every 30 centimeters in diameter – point to the same region of the sky as space telescope Kepler has already observed. To find your way faster. Around constellation of the Swan and of the Lira. Specially designed to overcome the noise Kepler discovered around solar-type stars, they can track transits onexoplanets.

The seventh ET mission telescope will face the center of ours Milky Way. With the aim of identifying the phenomena of gravitational microlenses in particular to betray the presence of certain wandering exoplanets. Planets no longer attached to a star. And actually, it’s even harder to flush.

More than a dozen Terres 2.0 to be found

Because, what the ET mission is looking for is not just planets the size of Earth orbit around the stars similar to ours Sun and far close to what we know of our Planet, but all terrestrial type planets. Also those whose orbits are different from our Earth and therefore, possible rocky planets laags.

Chinese researchers have already done some simulations. They announced that the ET mission should find about 29,000 new exoplanets. Among them, nearly 4,900 are the size of our Earth. And, considering that the occurrence rate on rocky planets similar to ours is 10%, probably between 10 and 20 Earth 2.0. All from 2030, therefore.

If these Lands 2.0 are already known, their composition still needs to be studied atmosphere and to determine if water can flow over their surface. Next, researchers should look for biomarkers – such as methane or oxygen – or technosignatures – such as transmissions radio – which may indicate that life developed there.

The white paper published by the researchers leading the project also tells us that the ET mission doesn’t stop there. It also focuses on tens of thousands of things in our Solar systemon comets or others asteroids. As well as some of our oldest stars Milky Way. To help better understand our evolution galaxy.
