Now that brave explorers have trekked through Antarctica, Santa Claus’s North Pole warehouse, and Gary Busey’s garage, scientists can confirm that space is the final frontier. Travel beyond Earth's atmosphere with today’s Groupon: for $6, you get two tickets to a planetarium show at the Whitworth Ferguson Planetarium (up to a $12 value). Shows are typically held on Friday evening and Saturday afternoon at varying times; attendees must use the Iroquois Drive entrance.

Since opening its star-dappled doors in 1964, the Whitworth Ferguson Planetarium has delighted sky-gazing enthusiasts through effulgent re-creations of the night sky and educational journeys through the solar system with its 24-foot-diameter dome, capable of illuminating 4,000 stars. Upcoming celestial explorations include Uranus and Neptune: Planets of the Telescope Age (January 13–February 11), which explores the planets and their improbable journey from two young marbles growing up in The Bronx to two of the solar system's gas giants. The vivid Shorter Nights: Passage Into Spring (February 17–March 24) reveals the dazzling sights visible in the Buffalo sky in the buildup to the equinox. Otherwise, Pluto and the Other Dwarfs: Smaller Objects of the Solar System (March 30–April 28) guides sojourners on a quest to view the celestial orb as it hides, weeping over its stripped status as a planet, behind Saturn's rings. Shows change regularly, so visitors should check the schedule for additional upcoming offerings.
