Planetarium, the Planetarium upgraded to an Evans & Sutherland Digistar 1 vector display in 1988, and was the first in the U.S. and third in the world to adopt multiple-projector digital image capability using the Sky-Skan SkyVision system in 1998. That allowed it to show fulldome movies, many of which were created by HMNS staff. Since 2004 its outreach program, "Discovery Dome", takes the planetarium experience on the road, reaching over 40,000 students per year in classrooms and special events in portable digital domes. Cockrell Butterfly Center, a butterfly zoo located in museum complex. Opened in 1994, the center is housed in a three-story glass building filled with tropical plants and butterflies. The center exhibits a large range of live butterflies, including the migratory monarchs and their tropical cousins. The Cockrell Butterfly Center was reopened in May 2007 after being overhauled to make the exhibit more interactive; there are now games for children and a live insect zoo in the Brown Hall of Entomology. Wortham Giant Screen Theatre, a 394-seat theater presenting various educational films in 4K digital with advanced 3D technology on its 60x80 foot screen. George Observatory, an astronomy observatory equipped with three domed telescopes, including a Gueymard Research Telescope and a solar telescope. The facility is located south of Sugar Land, Texas at Brazos Bend State Park. The observatory also houses a portion of the Challenger Learning Center for Space Science Education.
