Established in 1973, it was the first science museum to combine interactive science exhibits with a planetarium and an IMAX Dome ( OMNIMAX ) theater, setting the standard that most major science museums follow today.

The planetarium opened in 1973 as the Reuben H. Fleet Space Theater and Science Center showing two features, Voyage to the Outer Planets ( a combined planetarium show and OMNIMAX film produced by Graphic Films ) and the OMNIMAX film Garden Isle ( by Roger Tilton Films ) on a double bill.

The dome system, which the San Diego Hall of Science called OMNIMAX, uses films shot with a camera equipped with a fisheye lens on the camera that squeezes a highly distorted 180 ° field of view onto the 65 mm IMAX film.

For example, Cinerama used a curved screen and IMAX Dome / OMNIMAX movies are projected on a dome above the spectators.

The centre entered its first title sponsorship agreement with Alcan Inc. in 1996, renaming its OMNIMAX Theatre the Alcan OMNIMAX Theatre.

Alcan has since decided to sponsor the organization in different ways and the theatre has returned to its original name, the OMNIMAX Theatre.

In 1987, the centre saw a significant expansion with the opening of Singapore's first and only OMNIMAX ( now known as IMAX Dome ) theater, the Singapore Omni-Theatre.
