China Proposes Alien Planet  Worlds 

Mission to Hunt Habitable 

A proposed Chinese mission 

would look for nearby potentially habitable alien worlds by launching a spacecraft for scaning wobbling stars

For this mission, called the 

Closeby Habitable Exoplanet Survey (CHES), the scientists would use a method called micro-arcsecond relative astrometry.

This technique involves 

taking ultraprecise measurements of the positions and movements of stars compared with a background reference stars

This technique will detect

 the perturbations of a star resulting from the gravitational influence of exoplanets as they orbit their stars. 

CHES would be much

 more focused than Gaia, targeting 100 sun-like stars within 10 parsecs, or 33 light-years, 

IT would be able to

 detect potentially Earth-like planets in the habitable zones around those stars.
