Allhamdulilah dapat mengunjungi International Olympiad on Astronomy and Astrophysics
Astrophysics (Greek: Astro - meaning "star", and Greek: physis
– φύσις - meaning "nature") is the branch of astronomy
that deals with the physics of the universe,
including the physical properties of celestial objects, as well as their
interactions and behavior.
Among the objects studied are galaxies, stars, planets, exoplanets, the interstellar medium and the cosmic microwave
background. Their emissions are examined across all parts of the electromagnetic spectrum, and the
properties examined include luminosity,
density,
temperature,
and chemical
composition.
Because astrophysics is a very broad subject, astrophysicists
typically apply many disciplines of physics, including mechanics,
electromagnetism, statistical mechanics, thermodynamics, quantum mechanics, relativity, nuclear and particle physics, and atomic and molecular
physics. In practice, modern astronomical research involves a
substantial amount of physics. The name of a university's department
("astrophysics" or "astronomy") often has to do more with the
department's history than with the contents of the programs.
Astrophysics can be studied at the bachelors, masters, and Ph.D. levels in aerospace engineering, physics, or
astronomy departments at many universities.
