Welcome to The Planetarium at UT Arlington!
Black Holes Canceled April 30
Due to technical problems the 6:00 pm showing of Black Holes tonight, April 30, has been canceled. We apologize for any inconvenience.
Dynamic Earth Canceled May 1
Due to our special free public lecture "Flying With SOFIA" on Friday, May 1st, the regularly scheduled 6:00 pm showing of Dynamic Earth will be canceled. We will return to our regular schedule on Saturday, May 2. We apologize for any inconvenience.
Flying With SOFIA
May 1st at 6:00 PM
Come enjoy an evening of astronomy with M.J. Tykoski as she shares her story of flying with the Stratospheric Observatory for Infrared Astronomy(SOFIA).
M.J. Tykoski is an 8th grade science teacher at Cooper Junior High School in Wylie, TX and has won multiple awards of distinction; including a 2013 Butler Award for Excellence in Science Teaching, a 2009 Middle School Teacher of the Year Award from the Science Teachers' Association of Texas, the Texas Earth Science Teachers' Association Teacher of the Year Award in 2014 and was a 2015 National Finalist for the Edward C. Roy Jr. Award for Excellence in Earth Science Teaching from the American Geosciences Institute.
The event is sponsored by the SOFIA Project and is open to everybody. There is no charge to attend. There will be a reception at 5:30 PM in the Planetarium Atrium.

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.
- 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.
