The Planetarium at UT Arlington
Welcome to The Planetarium at UT Arlington!
No Planetarium Shows August 25th - September 3rd
The planetarium is closed through Wednesday, September 3rd as we perform necessary maintenance to our system to make sure that your experience is the best possible experience! We apologize for any inconvenience. We will re-open Thursday, September 4th with our regular public schedule.
The Planetarium offers live stargazing and pre-recorded programs to the public, school groups, and UT Arlington students all year round. Using state-of-the-art technology and a 60-ft. dome screen; the Planetarium is an immersive space theater facility with endless capabilities. Our shows are one-hour long and consist of ~30-minutes of stargazing of tonight’s night sky presented by a space scientist, and another ~30-minutes pre-recorded program.
Public is encouraged to check the Now Showing schedule for show times. Teachers can schedule their field trip using the Field Trip Scheduler form.
- The Lunar Reconnaissance Orbiter (LRO) scientists mentioned the Moon's craters that have ice in them are probably charged up by static electricity from interacting with the solar wind. Is there a way to measure the voltage from some probe or other?
- This might be a good one to try to send to the LRO scientists because this will be depend on the amount of ice, as well as electromagnetic field strength caused by the solar wind. Unfortunately, static electricity can’t be measured by probes unless the voltage carrying medium is grounded and discharged. For example, we can’t measure the static electric voltage building up in clouds. However, if we knew the amount of current that was transmitted to a lightning rod by the cloud, then we would be able to estimate the amount of static electricity carried in the cloud just before the lightning.
- Can we experience weightlessness near a black hole?
- I don’t think that you would feel weightless around a black hole, because the difference in gravity between your head and feet is so great that you will be stretched into a long thin string. Even if you can get into a fast orbit around the black hole that would attempt to balance the gravitational forces, creating a free fall situation (exactly the same situation the astronauts have around Earth) you would still feel this stretching on your body. Some astronomers like to call this stretching effect, spaghettification, because it stretches you into a thin piece of spaghetti. You will eventually become stretched so much, that the bonds holding your atoms together will break, so it won’t be you that enters the black hole, but the protons, neutrons and electrons that make you up.
- How long would it take to get to Venus going 60 miles per hour?
- Venus’s distance from Earth varies depending on where each planet it is its orbit around the Sun. The closest that Venus ever gets to Earth is 23.6 million miles. That means that it would take 44.9 years to reach Venus travelling at 60 mph!
- Has NASA spotted an exoplanet orbiting Alpha Centauri a and b and proxima centauri?
- Yes! A planet, known as Alpha Centauri Bb, was discovered orbiting around Alpha Centauri B, which is part of a three-star system just 4.3 light-years away from us. Alpha Centauri Bb zips around its star every 3.2 days, orbiting at a distance of just 3.6 million miles (6 million kilometers) and is approximately the same size as Earth. For comparison, Earth orbits about 93 million miles, or 150 million km, from the sun.

See what it takes to become an Astronaut and the effect space has on the human body.
Discover the night sky with Big Bird, Elmo and their new friend from China, Hu Hu Zhu.
Pink Floyd is the classic that everyone loves. Combine that with the amazing visual effects and you have an absolutely amazing show that no one should miss.
The fastest fulldome show continues with 9 all new rides!
Follow two students as they interact with an astronomer at a local star party. Along the way the students learn how telescopes work, the history of telescopes, and major discoveries made by these instruments.
Do you know what an astronomer does? Today's astronomer is not the lone observer of past centuries. We Are Astronomers reveals the global collaboration, technology, and dedication required to answer the unresolved questions of the Universe.
