As Earth places its bid for the 2020 Intergalactic Winter Olympics, today's Groupon invites you to rediscover what makes the universe so neat (hint: pretty much everything). For $30, you get a one-year individual membership (a $65 value) to the Adler Planetarium. You can also get a family membership for $40.

The Adler Planetarium has been making an argument for the existence of space since it opened its doors as America's first planetarium in 1930. Its majestic Sky Theater translates the enormity of the night sky into a more easily comprehended dome ceiling. Unlimited daytime tickets and discounted evening tickets are available to members. Future astronauts and doubting astro-nots will receive a mind-expanding crash course in constellations, atmospheric gases, dark matter, black holes, lunar expeditions, nebulae, supernovae, and the odd profligacy of space-battles that have been observed in a galaxy far, far away—for starters. But like the cosmos themselves, there's more. So much more.

This membership grants you unlimited admission to the planetarium and its many shows and exhibitions, including One World, One Sky: Big Bird's Adventure, the Robert Redford–narrated meteor-fest Cosmic Collisions, and the musically coordinated 3D Universe: A Symphony, which proves that the music of the earth can elevate even the music of the spheres. The family membership covers unlimited admission and theater tickets for two adults and up to six children under 18 years old, while the individual membership covers unlimited admission for you and one guest. Both memberships include the added benefits of a 15% discount at the Infinity Gift Shop, 10% off in Galileo's Cafe, VIP access to new exhibitions, two complimentary guest passes for general admission, discounts on guided tours, and more. See the full list of privileges here. If nothing else, the planetarium provides a place where your love for dehydrated ice cream can blossom without judgment or water.


Frommer's recommends the Adler Planetarium, saying:

  • The building may be historic (it was the first planetarium in the Western Hemisphere), but some of the attractions here will captivate the most jaded video-game addict. Your first stop should be the modern Sky Pavilion, where the don't-miss experience is the StarRider Theater. Settle down under the massive dome, and you'll take a half-hour interactive virtual-reality trip through the Milky Way and into deep space, featuring a computer-generated 3-D-graphics projection system and controls in the armrest of each seat. Six high-resolution video projectors form a seamless image above your head -- you'll feel as if you're literally floating in space. – Frommer's

Yelpers and Insider Pagers alike give the Adler Planetarium four stars, while Judy's Book reviewers give it 4.4. TripAdvisors give it a solid three owl eyes:

  • When it comes to Chicago museums, the Planetarium is often forgotten or overlooked. However, it's a great place to spend a day during any season. – Neal H., Insider Pages
  • The Planetarium is a fascinating place to visit. The exhibits, telescopes, and tours all-together make the Planetarium a worthwhile place to see. – Oscar Y., Judy's Book
  • There are tons of hands-on displays, and not just for kids.... All the displays really get you involved and find a way to make sometimes dull topics interesting. – Jenny S., Insider Pages

The Adler Planetarium

Historic spacecraft, fragments of far away worlds, and maps of the galaxy make outer space seem completely within reach. That's the magic of the Adler Planetarium. From the moment visitors pass through the Clark Family Welcome Gallery—a portal of aluminum tubing, fabric, and video projections—they embark on a journey through space, time, and imagination.

  • Eye Catcher: Earth's neighbors and one massive yellow Sun hang overhead in Our Solar System, which also includes a fragment of a meteorite and a replica of the Mars rover. The Adler is the only place where visitors can touch a piece of the Moon, Mars, and three different asteroids under one roof.
  • Permanent Mainstay: The Historic Atwood Sphere, Chicago's oldest planetarium, where guests can step under a steel dome to view the night sky as it appeared in 1913 thanks to 692 drilled holes.
  • Hands-On Experiments: In The Universe: A Walk Through Space and Time, you can send yourself digital postcards from across the Universe; it'll only take four hours for one to arrive from Neptune, but be prepared to wait 2.5 million years for one to arrive from the Andromeda galaxy.
  • Hidden Gem: The Space Visualization Lab introduces guests to cutting-edge research that astronomers discuss with visitors one-on-one to convey the vastness of space or the size of the castle they want to build on the Moon.
  • Don't Miss: The live planetarium show, Destination Solar System, blends a sci-fi plot with real science as it journeys to Mars, Jupiter, and Saturn's moon Titan.
  • Special Programs: Every third Thursday of the month, Adler After Dark lets amateur astronomers 21 and older spend the evening gazing at the stars with cocktails in hand.

Bring a bag lunch the food is high

Lots of kids at the end of the year on field trips. Better to attend in the fall during the week if you want a quieter experience with the ability to participate in the hands on displays.

Great opportunity and there's a beautiful view of Chicagos skyline
