"</ P> <P> lunar observatory built at the same time, Dr. Chen plans to create a diameter of 50 on the Moon .meter telescope. .As long as there is a moon or two such telescopes, we can more effectively help astronomers search for planets outside our solar system, to a galaxy far away to do a more detailed observation. .World Scientific reports </ P> </ p>.
