Theoretical Astrophysicist
Theoretical astrophysicists study the laws of nature in space, using these discoveries to help us understand how the same laws work on our planet. Did you know that helium was discovered in the Sun before it was identified here on Earth? Theoretical astrophysics helps us learn how stars shine, where they’re located, what orbits them, and how they come to exist. Scott Tremaine, of the Institute for Advanced Study, uses math and physics to find planets and explore black holes. To find out more, check out
