NASA Astrophysics In the Science Mission Directorate (SMD), the Astrophysics division studies the universe.  The science goals of the SMD Astrophysics Division are breathtaking: we seek to understand the universe and our place in it. We are starting to investigate the very moment of creation of the universe and are close to learning the full history of stars and galaxies. We are discovering how planetary systems form and how environments hospitable for life develop. And we will search for the signature of life on other worlds, perhaps to learn that we are not alone. NASA's goal in Astrophysics is to "Discover how the universe works, explore how it began and evolved, and search for life on planets around other stars." Three broad scientific questions emanate from these goals. How does the universe work?  - Probe the origin and destiny of our universe, including the nature of black holes, dark energy, dark matter and gravity. How did we get here?  - Explore ...

Astrophysics What is Astrophysics? Astrophysics  is a branch of space science that applies the laws of physics and chemistry to explain the birth, life and death of stars, planets, galaxies, nebulae and other objects in the universe. It has two sibling sciences, astronomy and cosmology, and the lines between them blur. In the most rigid sense: Astronomy measures positions, luminosities, motions and other characteristics Astrophysics creates physical theories of small to medium-size structures in the universe Cosmology does this for the largest structures, and the universe as a whole. Goals of astrophysics Astrophysicists seek to understand the universe and our place in it. At NASA, the goals of astrophysics are "to discover how the universe work, explore how it began and evolved, and search for life on planets around other stars," according  NASA's website . NASA states that those goals produce three broad questions: How does the uni...
