An "incredible" and "surreal" video call with Chinese astronauts in outer space has deeply impressed Hong Kong students curious about the mysteries of the universe, driving them to explore more of the marvelous world around them.

In a Friday seminar in Hong Kong, three crew members of the Shenzhou XII spacecraft — now in the country's Tiangong space station — took questions from Hong Kong students in a live call, sharing their work and life in outer space. Some aerospace experts in Beijing also shared information on the nation's space exploration to the Hong Kong audience in a video chat.

Marco Clark, an aerospace engineering student at Hong Kong University of Science and Technology, said is the talk was an incredible opportunity the country offered to Hong Kong, and an incredible moment for young students to become the next generation of astronauts or tech-nauts, he said.
