Deep Sea Highlights

  • Sperm Whale
  • See the Unseen connection to your ocean dwelling relative. See what lies beneath the outer layers and glimpse inside the skeleton of a life-size Sperm Whale. At more than 30’ long, the exhibit piece is about the size of a small adult female Sperm Whale.
  • Creature Reveal: ROV
  • See the Unseen universe buried deep below the waves. Follow the search lights of the undersea Remotely Operated Vehicle to explore the depths of the ocean.
  • LED Video Wall
  • This custom size 19’x7’ LED Video wall has a 2.9mm full HD resolution and shows a custom made 9-minute video aquarium. The bright, vivid colors and rich picture of this display are jaw-dropping and can be seen from the top of the stairs in Science Alley and from the bridges connecting our exhibit halls.

Terra Firma Highlights

  • Tyrannosaurus Rex
  • See the Unseen relationship between predators that once roamed our planet and animals today. The similarities are astonishing when you peer inside this massive T. rex head and torso.
  • Tornado
  • See the Unseen energies that drive extreme weather events. This giant display features video of extreme weather and actual artifacts from the tornados that touched down in Springfield, MA in 2011.
  • Volcano
  • See the Unseen forces deep below the surface. Fueled by heat from our planet’s fiery core, these tectonic plates are constantly moving. When a weak spot develops, hot, molten rock might rush toward the surface, producing a spectacular, spewing volcano.

Aerospace Highlights

  • Hubble Space Telescope
  • See the Unseen through space and time with a mirror a hundred times bigger than your eye. Launched in 1990, Hubble is one of NASA's most successful and long-lasting science missions. It has beamed hundreds of thousands of images back to Earth, shedding light on many of the great mysteries of astronomy. The Science Alley scale model is about 1/3 the size of the actual telescope that is nearly the size of a large school bus.
  • Helicopter
  • See the Unseen innovations that make flying possible. Explore the four forces of flight - lift, thrust, drag, and weight - in this model of a U.S. Coast Guard Helicopter.
  • Mercury-Redstone Rocket
  • See the Unseen power of exploding fuel. The Mercury-Redstone Rocket is the same size as the real rocket, Freedom 7, that sent Alan Shepard into orbit on May 5, 1961.
