Africa-Press – Rwanda. The new space telescope would observe 1.2 million dwarf stars for four years, searching for distant planets akin to our own. A new proposal by the Shanghai Astronomical Observatory may result in China launching a new effort to search for exoplanets similar to our home world in outer space.
According to Space.com, the proposed Earth 2.0 Telescope would be deployed some 1.5 million kilometres from our planet, where it would orbit Sun-Earth Lagrange point 2 for four years and use its seven telescopes to seek out hints of exoplanets’ presence – such as when a star dims when a planet passes in front of it – at a particular section of the sky towards the galactic centre.
The primary targets of this endeavour are supposed to be exoplanets similar in size to Earth that orbit stars similar to our Sun. However, a professor at the Shanghai Astronomical Observatory named Ge Jian told the media outlet in an email that the spacecraft would merely measure the planets’ sizes and orbital periods, while the potential habitability of said planets would be assessed via observations from other facilities.
With a field of view of 500 square degrees, the Earth 2.0 Telescope would observe some 1.2 million dwarf stars over four years, the media outlet notes.
