The Planetarium at UT Arlington
Welcome to The Planetarium at UT Arlington!
International Observe the Moon Night
Join us for International Observe the Moon Night on Saturday, September 19th from 4:00 pm - 10:00 pm. We'll have telescopes set up for viewing the Moon (weather permitting), special guest lectures from the President of the Moon Society and special Planetarium shows about the Moon!
The Planetarium offers live stargazing and prerecorded 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 approximately 30-minutes of stargazing of tonight’s night sky presented by a space scientist, and another 30-minutes of prerecorded video.
Total Lunar Eclipse
On Sunday, September 27th, North America has a front row seat to one of the best-timed total lunar eclipses in recent memory. The moon will be completely engulfed by Earth's umbra (center of shadow) from 9:10-10:20 p.m. Our staff will have several powerful telescopes set up on the 3rd floor balcony of the planetarium from 7:00 p.m. - 12:00 a.m. to showcase this stunning celestial sight. We'll also have discounted Planetarium shows and special guest lectures from the President of the Moon Society.
- 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.

The night sky, both beautiful and mysterious, has been the subject of campfire stories, ancient myths and awe for as long as there have been people. A desire to comprehend the Universe may well be humanity’s oldest shared intellectual experience. Yet only recently have we truly begun to grasp our place in the vast cosmos. To learn about this journey of celestial discovery, from the theories of the ancient Greek astronomers to today’s grandest telescopes, we invite you to experience From Earth to the Universe.
Pink Floyd is the classic rock that everyone loves. Combine that with the amazing CG visual effects and you have an absolutely amazing show that no one should miss.
