Welcome to ePlanetarium

We offer fully portable digital theaters with true HD (using all the width of 1920 and most of the height), with fulldome movies and zoom-in digital starfields. With support from NASA REASoN and a strong partnership with museums and universities, we bring the excitement of museum-quality shows, presenting a wide range of educational topics, in a state-of-the-art mobile digital theater system, to you. Our domes are fully flame retardant and handicapped-accessible, and users can come and go during a show. We offer new portable inflatable domes, new high-resolution projectors, and educational and entertainment shows, in additional to bringing "on the road" programs to schools and special events. Daily rentals available from our extensive partner network.

ePlanetarium®, along with Space Update®, is a division of MTPE, Inc., a woman-owned small business. "Brings the Professor to You"™.


Why Choose ePlanetarium?


Discover the Difference!

This isn't your old crawl-in star dome!

  • Fulldome Video with Sound: museum-quality fulldome shows are available on all science topics; project a dynamic night sky with stars, planets, constellations, and more.
  • Shows aligned with Science Objectives: over 80,000 students experienced a Discovery Dome in Houston alone in 2011 .. and over 90% of the teachers chose an educational movie instead of a star show... because it met their educational objectives!
  • Upgradeable Components: high-end off-the-shelf components can be upgraded as new projector or computer technology is released - never be stuck with old technology again! And get LOCAL service on your projector and laptop!
  • High Definition Resolution: true 1920x1080 gives sharp, vivid, images which fill virtually the entire dome!
  • Double the Pixels: almost twice as many pixels projected as Digital Starlab or the Digitarium Gamma from Digitalis! (They use only a 1080 circle - we use all 1920 across. We even have 30% more pixels than Digitarium epsilon.)
  • Walk-in Dome: stand up entry, no crawling required; continuous entry and exit without disrupting a show; handicapped accessilble! Special flap to allow projection even on the doorway. Widest range of sizes, types, and colors of any dome manufacturer - now with the new semipermanent Zodiac dome for sale or rent! Beware of imitations - we use only Go-Domes™!
  • 3D Available: Our new projectors change in a flash from fulldome to 3D - NO OTHER SYSTEM is that flexible! And now with "Mediawaarp 3D" available in our special 3D upgrade.
  • Custom Projection Surface: minimizes wrinkles, crosstalk, and sound echoes. Self-closing vents (now copied by Digitalis) allow ventilation without bouncing; resists deflation when large groups exit.
  • Highly Mobile: fast set up (less than 20 minutes), easy to operate, lightweight, easy for one person to carry in a compact car or check as airline luggage.
  • Ease of Use: MediaSHOW is designed for ease of use in having full control of images, movies, sequences, and clips. Training takes just a few minutes and is included in the price. And it is easy to create your own custom show from clips, stills, and sound!
  • Starfield Software: Stellarium, included free, is a collaborative software application that uses the talents of the entire community to provide the best software! For permanent installations, we offer the high quality "Sky-X" display and authoring "Theater Suite" from Software Bisque - good for Macs or Windows!
  • Compare to Digitalis or Starlab: See more reasons to choose Discovery Dome over Digitalis or Starlab by seeing our comparison.
