Astrophysics: The Science of Stars, Galaxies, and the Universe

ASTROPHYSICS is the branch of science that applies the laws of physics and chemistry to explain the birth, life, and death of stars, planets, and galaxies. Think of it as detective work on a cosmic scale — scientists gather LIGHT, radiation, and data from across the universe and use those clues to reconstruct what is happening billions of light-years away. One of the most thrilling aspects of astrophysics is that researchers can study objects they will never physically touch or visit, relying entirely on the information carried to us by ELECTROMAGNETIC radiation. The ELECTROMAGNETIC SPECTRUM stretches from radio waves all the way to gamma rays, and each type of radiation reveals something different about the universe's structure and history. Astrophysics sits at the intersection of curiosity and rigorous EVIDENCE, asking the deepest questions humans have ever posed: How did the universe begin? How will it end?
