The Closeby Habitable Exoplanet Survey (CHES) mission, developed by the Purple Mountain Observatory of the Chinese Academy of Sciences,
The space telescope must measure the minimumchanging the relative positions of these stars in the sky to search for Earth-like planets around them. CHES needed to measure the star's wobble to within 1 microsecond of arc, which, by comparison, is just one millimeter of motion on the Moon as seen from Earth.
Such a study, as the authorsdevelopment will require 10 times greater measurement accuracy than that currently used in the world's flagship astrometric missions. To achieve this accuracy, researchers use focal plane laser metrology technology.
The project will be reviewed shortly.experts from the Chinese Academy of Sciences. If approved, the team plans to complete construction of the telescope in five years and put it into orbit at the L2 Sun-Earth Lagrange point. Scientists believe that CHES will be able to detect about 50 Earth-like planets.
Researchers note that most of the moreMore than 5,000 exoplanets discovered to date are many larger than Earth or in the habitable zone of smaller, cooler stars. The likelihood of the existence of water and life, as we imagine it, is much lower on such exoplanets.
Scientists believe that the new space telescope will help to find the real twins of the Earth - a planet of the same size and mass as ours, and orbiting in the habitable zone around a sun-like star.
