Nearly 10 years ago, Infinity Express debuted at the Smithsonian’s then-newly refurbished Albert Einstein Planetarium at the National Air and Space Museum. Projected on the planetarium’s dome, the 20-minute film was a museum mainstay for years, immersing viewers in an epic trek through the universe, combing actual images from space as well as artful animations. Laurence Fishburne’s dark-side-of-the-moon narration added to the consciousness-expanding atmosphere. But alas, every trip must come to an end: With new cosmic discoveries, better technology, and fresh films being made to illustrate those revelations, Infinity Express was shelved in 2006, leaving movies such as Journey to the Stars and Cosmic Collisions to carry the celestial load. But like a comet, Infinity Express has returned. Showings began Dec. 18 and will continue through next fall, giving space-heads a chance to reengage with one of the planetarium’s brightest stars.

The film shows daily at the National Air and Space Museum, Independence Avenue and Sixth Street NW. No showings Dec. 24 and 25. Free. 866-868-7774.
