(Update)

China is set to launch its new space lab, Tiangong-2, in the coming weeks, and the country is promising that the lab will offer a "splendid" show for skywatchers around the world.

The Tiangong-2 space lab is larger than China's previous lab, Tiangong-1, and it is equipped with a number of advanced features, including a robotic arm and an airlock. The lab will be used for a variety of experiments, including microgravity experiments and life science experiments.

According to Chinese officials, Tiangong-2 will be visible from Earth with the naked eye, and it will be especially bright and easy to see during the early morning and evening hours. Skywatchers in the northern hemisphere will have the best views of the lab, but people in the southern hemisphere will also be able to see it with the help of binoculars or a telescope.

The Tiangong-2 space lab is expected to remain in orbit for about two years, and it will be visited by a number of Chinese astronauts during that time. The astronauts will conduct experiments, maintain the lab, and work on the development of new technologies for future space missions.

China is investing heavily in its space program, and the Tiangong-2 space lab is a key part of that effort. The lab will allow China to conduct more advanced experiments in space, and it will help the country to train astronauts for future missions to Mars and other planets.

Update: The Tiangong-2 space lab was successfully launched on September 15, 2016. The lab is currently in orbit, and it is visible from Earth with the naked eye. Skywatchers in the northern hemisphere have the best views of the lab, but people in the southern hemisphere can also see it with the help of binoculars or a telescope.
