China Plans World’s First Habitable Planet Search With Space Telescope

China Plans World's First Habitable Planet Search With Space Telescope_4.1

Chinese scientists have proposed a space project to survey the sky through a space-borne telescope to hunt for habitable Earth-like planets outside the solar system, about 32 light-years from Earth. The project, named Closeby Habitable Exoplanet Survey (CHES) would be the first space mission specially designed to search for habitable terrestrial planets around nearby Sun-like stars.

The exploration of habitable planets outside the solar system is one of the key frontiers of fundamental research in astronomy. The discovery of the nearby habitable worlds will be a great breakthrough for humankind, and will also help humans visit those Earth twins and expand our living space in the future.

Key points:

  • The CHES will observe about 100 Sun-like stars 32 light-years away on a long-term survey, and will hopefully discover roughly 50 Earth-like planets or super-Earths, planets that are up to about 10 times the mass of Earth.
  • CHES will offer crucial clues to the issues such as other extra-terrestrial lives and the planets becoming the cradle of life.
  • 5,000 exoplanets have been discovered and confirmed so far, including about 50 Earth-like planets in the habitable zone, but most of them are hundreds of light-years away from Earth.

Important takeaways for all competitive exams: 

  • China Capital: Beijing;
  • China Currency: Renminbi;
  • China President: Xi Jinping.
