The Science Museum of Minnesota’s annual festival of films on its 90-foot domed Omnitheater screen celebrates two decades this year.

Omnifest, which runs Jan. 4 through Feb. 28, will feature five movies running in rotation in the William L. McKnight-3M Omnitheater. Because it’s a special milestone for Omnifest, the movies are special, too. All five films are works that the Science Museum of Minnesota, the largest museum producer of giant screen films, has had a hand in producing: “Ring of Fire,” “Journey to Space,” “The Greatest Places,” “National Parks Adventure” and “Tornado Alley.”

According to a Science Museum news release, the 2019 festival is the last festival that will take place on film in the Omnitheater. Later in the year, the theater will convert from a giant screen film projection system to a digital laser projection system. The new projection system will mean better contrast, brightness, clarity and color, according to museum release.

There are also more Omnitheater movies to choose from in the digital format, the Science Museum said.

Here are the movies for the 2019 Omnifest.

‘Ring of Fire’

A look at the great circle of volcanoes that rings the Pacific Ocean. “In this Science Museum of Minnesota original production, visitors will get a front-row seat for the spectacular eruptions of Mount St. Helens and Sakurajima in Japan. They’ll see the birth of a new volcano in southern Chile, and they’ll meet people who live within the shadows of some of the world’s most active volcanoes.”

‘Journey to Space’

“Magnificent giant screen views of Earth and footage of remarkable operations in space — including the deployment and repair of the famous Hubble Space Telescope. Viewers will get a sweeping overview of past space accomplishments, current activities and future plans, showcasing how the Shuttle launched and assembled the International Space Station.”

‘National Parks Adventure’

Viewers take a journey to 30 national parks — “from Yellowstone’s famous geysers to the soaring Devil’s Tower, from the raging rivers of Denali National Park to the teeming wildlife of the Everglades.”

‘The Greatest Places’

“This Science Museum of Minnesota original production blends trips to Tibet’s Chang Tang Plateau, South America’s Iguazu Falls and Amazon River, and the enormous icebergs of Greenland with forays to the world’s tallest sand dunes in the Namib Desert, the Okavango Delta in Botswana and the island nation of Madagascar.”

‘Tornado Alley’

“Viewers will join ‘Storm Chasers’ star Sean Casey and the researchers of VORTEX2, an ambitious project that seeks to understand the origins and evolution of tornadoes, on a science adventure through the ‘severe weather capital of the world.’ Armed with a 70-mm camera, a fleet of customized vehicles designed to withstand gale force winds, torrential rains and unrelenting hail, and an arsenal of the most advanced weather measurement instruments ever created, Casey and the VORTEX2 researchers will attempt to surround tornadoes and the supercell storms that form them, gathering the most comprehensive severe weather data ever collected.”
