Researchers in the Astrophysics Branch study the physical and chemical properties of astronomical objects and phenomena by observing their radiation at optical, infrared and ultraviolet wavelengths..
Astrophysicists are a special type of physicist who studies the basic workings of the universe at the scale of stars and planets..
Astrophysics – Studying astrophysics means looking at the physics and properties of celestial objects, including stars, planets and galaxies, their properties and how they behave.
You could even study whether or not time travel is possible..
Some areas of study for astrophysicists include their attempts to determine the properties of dark matter, dark energy, black holes, and other celestial bodies; and the origin and ultimate fate of the universe..
Most astrophysics research is done by universities and government organizations such as NASA.
Astronomers, among which astrophysicists are often counted, usually work at universities as professors and spend most of their time teaching, alongside research using data obtained by observatories and satellites..
It began with Isaac Newton
While astronomy is one of the oldest sciences, theoretical astrophysics began with Isaac Newton.
Prior to Newton, astronomers described the motions of "heavenly bodies," as they were then called, using complex mathematical models without a physical basis..
