Astrophysicists

An astrophysicist is a scientist who researches the principles of light, motion, and natural forces as they pertain to the universe at large. Astrophysicists engage in theoretical physics studies in an attempt to learn more about the underlying properties of the cosmos. Many specialize in studying a particular phenomenon or theory, such as black holes, the development and extinction of stars, relativity and motion, or the origin of the universe. 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. Astrophysicists incorporate their extensive knowledge of mathematical and physical properties with observable characteristics to form modern explanations. So much is unknown or uncertain about the universe that it is not uncommon for them to spend the majority of their career investigating a single astronomical circumstance. Astrophysicists study how the universe works, explore how it began and evolved, and search for life on planets around other stars. In simple words, they seek to understand the universe and our place in it. This section provides you information about the life and works of famous astrophysicists.
