About the George

The George Observatory, located about one hour’s drive south of Houston in the attractive Brazos Bend State Park, is a satellite facility of the Houston Museum of Natural Science. The Observatory houses a Challenger Learning Center for Space Science Education, which takes participants on simulated space missions, complete with a mission control center and a spacecraft simulator. A meteorite exhibit features fragments of several famous meteorites, including a piece of the Allende, Chihuahua, Mexico carbonaceous chondrite meteorite, which fell to the Earth on Feb. 8, 1969. This is the most primitive type of meteorite known contains interstellar grains (stardust) and is believed to have formed during an explosion of a supernova/red giant star before the birth of the solar system, making it one of the oldest substances known to man.

There are also three domed telescopes at the George Observatory: the largest is the 36-inch Gueymard Research Telescope, one of the largest telescopes in the nation open to the public on a regular basis. The George Observatory  has a new 11 inch F 15 refracting telescope donated by Preston and Donna Engebretson of Houston, Texas. The 11 inch is mounted on the Gueymard 36" (.9 meter) RC Tinsley Reflector.

Used for inquiry and education, the telescopes at the Observatory allow both amateur and professional astronomers to conduct research, while visitors can gain firsthand knowledge of the beautiful and awe-inspiring sights of the night sky. Depending on the time of the month and the season of the year, visitors are able to observe a variety of phenomena, such as Saturn’s rings, cloud belts on Jupiter, a partial or total eclipse of the Moon, a bright meteor or fireball that lights up the ground, the Milky Way, or a close pairing of two planets.

The George Observatory is open for public viewing on Saturday evenings, and is available by reservation on Friday nights for groups of 30 or more. During weekdays, school groups can attend astronomy classes by reservation. These classes feature a special tour of the research telescope and a view through a solar telescope, allowing visitors to see sunspots, flares, and the ever-changing gas prominences of the Sun.

Observing for High School, College and/or Adult Education Astronomy/Physics Classes

These observational classes are held on one Thursday evening per month, November-March, from 6:30 - 8:30 pm.

Teachers/professors:  Bring your class to the George Observatory in Brazos Bend State Park for a hands-on observing session through the 36 inch telescope and new 11 inch refractor here at the observatory.

Cost: $150 for up to 30 students and teacher. (plus park activity fee of $1.00 per person.)

For further information and reservations call the Observatory staff at 281-242-3055 or 979-553-3400.

LyondellBasell Educator Overnights at the George Observatory

Educators!  Join us at the George Observatory in Brazos Bend State Park for an Astronomy Overnight.  Work with experts in asteroid, meteor, lunar and planetary astronomy as you observe the night sky using the largest public telescope in the U.S.  Participate in a Challenger Mission and then stay up late to enjoy the night sky.  Feel free to bring your own telescope and binoculars.

*NOTE: participants must stay through the entire event to receive credit as partial credit is not available.

For more information about this Overnight program or to book a special program for your school’s teachers please contact the Overnight coordinator at overnights@hmns.org.
