Although The Planetarium at UT Arlington is by far the largest on campus, it's not the only one. In 1975, Physics Professor Ulrich Herrmann proposed that a quirky round building near the Library become the first UT Arlington planetarium.

  • How far apart are Betelgeuse and Rigel from each other? That is to say how large is the constellation Orion if measured from one of these stars to the other?
  • According to the celestial coordinates of the stars, they are 18.56 degrees apart in the sky. From these vectors, we can find the distance of Rigel to Betelgeuse; 392 light years This still doesn’t give any clue about how large the constellation is as we don’t know the distance from other stars yet (Think 3D; On Earth, Rigel appears on the right and is the farthest away, however that may not be true for the whole universe.) The best description of the size of the Orion would be as follows; The Orion Constellation’s size is about 18 degrees across in the sky.
  • General relativity proved that light can bend based on a lot of gravity being forced onto the light. What are the two proofs of this?
  • The fact that light is bent by gravity was predicted by Einstein's General Theory of Relativity. The first observational evidence was given by Eddington and his team, who measured the effect during a solar eclipse in 1919. The measured value was very close to the one predicted by Einstein's theory.
