Observational astrophysicists use telescopes to study the Universe, but astrophysicists study the physics of what they see to explain the Universe.
Theoretical astrophysics uses information from astronomers, theories and mathematics to explain how the Universe works.
Cosmology is a type of theoretical astrophysics..
United States (US) The United States boasts the best universities in the world to study Physics and Astronomy.
The country houses 118 institutes among the top 600 institutes in the world offering courses in the fields of Physics and Astronomy..
The graduate program in Astrophysical Sciences prepares students for scientific careers in astrophysics through a combination of classes and early and active participation in research projects, culminating in original thesis research.
The program length is five years..
A broad understanding of mathematics is required to perform the calculations necessary for data analysis and to understand astro mechanics, theory, etc.
At the University of Arizona it is required for an undergraduate to pass Calculus (2 semesters), Vector Calculus, and Ordinary Differential Equations..
Astrophysics involves a broad frontier of technologies including materials science, optics and electronics.
This three-year programme teaches students to apply their knowledge of physics to astronomical observation and to the interpretation of the data and images obtained..
Astrophysicists are a special type of physicist who studies the basic workings of the universe at the scale of stars and planets.
They pursue this knowledge using telescope observations and data collected by satellites and space probes..
According to the U.S.
Department of Labor, there are approximately 19,900 physicists and astronomers working in the United States.
Most work for scientific research and development services firms or colleges, universities, and professional schools..
Example areas of study are radio waves, usually emitted by cold objects such as interstellar gas and dust clouds; the cosmic microwave background radiation which is the redshifted light from the Big Bang; pulsars, which were first detected at microwave frequencies..
An astronomy and astrophysics major studies how the universe formed and the stars, planets, black holes, dark matter and galaxies that exist within it.
With a curriculum centered on physics and mathematics, astronomy majors also use data to observe and model the universe..
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..
Here are some fascinating astronomy facts that astronomy majors will encounter in their studies.
Our Sun is one of over 100 billion stars in the Milky Way galaxy
And the Milky Way is one of over 100 million galaxies in the universe. The planet Saturn would float on water-it's the only planet in our solar system that would. The black hole in the center of the Milky Way galaxy is millions of times the mass of the Sun.
