Astronomy
Astronomy is the study of everything in the universe beyond Earth’s atmosphere. This includes objects we can see with the naked eye, like the sun, the moon, other planets, and the stars. It also includes those we can only see with telescopes or other instruments, like faraway galaxies.
Astronomy measures the positions, luminosities, motions and other characteristics of celestial objects.
Increasing public interest in astronomy and improved scientific education have helped to develop a more skilled workforce.
These skills, both conceptual and practical, are easily transferred to applied fields such as meteorology, computer science and information technology.
Astronomy is divided into four sub-fields:
1. Astrophysics: Applying the laws of physics in space;
2. Astrometry: Mapping celestial bodies;
3. Astrogeology: Examining rocks, terrain, and material in space;
4. Astrobiology: Searching for life outside Earth.
Astrophysics is a branch of space science that applies the laws of physics and chemistry to understand the universe and our place in it.
It explores topics like the birth, life and death of stars, planets, galaxies, nebulae and other objects in the universe.
Astrophysics creates physical theories of small to medium-size objects and structures in the universe. Cosmology covers the cosmos’ largest structures and the universe itself.
Astrobiology
Astrobiology is the study of the origin, evolution, and distribution of life in the universe. This includes the search for life beyond Earth, studying environments that could support life and investigating interactions between planets and their stars and how this could influence life.
