Astrophysics: Exploring the Science of the Universe

ASTROPHYSICS is the branch of astronomy that uses the laws of physics and chemistry to explain the birth, life, and death of stars, galaxies, and the universe itself. Think of it as the detective work of science — astrophysicists gather LIGHT, radiation, and data from across the cosmos to piece together how everything came to be. Every time you look at a clear night sky, you are already doing what astrophysicists do: observing the universe and asking questions. The field spans an enormous range, from studying tiny PARTICLES smaller than an atom to mapping the largest known structures in existence. INQUIRY — the act of asking rigorous questions and testing them against evidence — is the engine that drives all of astrophysics forward. What makes this science so thrilling is that the universe itself is the LABORATORY, and every new telescope or detector is a new instrument on the bench.
