Would-be adventurers should head to the Hong Kong Space Museum's Space Theatre before Sunday.
That is the last day the Omnimax film Cosmic Voyage will be shown. It will be replaced by a new film, Special Effects, on Tuesday.
Mixing dazzling computer-generated imagery with cutting-edge science, Cosmic Voyage offers a sweeping view of the universe, from the tiniest particles to the largest galaxies.
The film shuttles viewers through time and space to witness the birth of the universe - the Big Bang - and hurls them back to earth to descend to the minuscule world of atomic particles, including the quark, the tiniest known object.
Filmed in Greece, Italy, Hawaii, Holland and the United States with narration in English, Cantonese, Putonghua and Japanese, the 35-minute show tackles concepts large and small and gives us a unique perspective on our place in a vast universe.
The film is shown daily at 3.30 pm, 5.30 pm, 7.30 pm and 8.30 pm, with additional shows at 1.30 pm on Saturday and 11.30 am and 1.30 pm on Sunday.
