The world's largest planetarium opened its doors to the public on Sunday.

There was a scramble to get tickets to the Shanghai Astronomy Museum. As soon as online reservation opened, tickets for the first week soon sold out.

The first 5,828 visitors joyfully made their way for the long-awaited visits to the museum on Sunday. Of them, Mao Yiwen, 18, arrived around 7:30am, two hours before the opening, becoming the first to enter the museum.
