SPACE

This is the site section dedicated to Space, the expanse that exists between celestial bodies, including Earth. Outer space is not completely empty, but consists of a hard vacuum containing a low density of particles, predominantly a plasma of hydrogen and helium as well as electromagnetic radiation, magnetic fields, neutrinos, dust, and cosmic rays.

The articles will cover two main disciplines: Astronomy and Astrophysics.
Generally the term “Astronomy” refers to the study of matter, objects outside the Earth’s atmosphere and their physical and chemical properties.
“Astrophysics” refers to the branch of astronomy dealing with the behavior, physical properties and dynamic processes of celestial objects and other phenomena.

In some cases it is said that astronomy can be used to describe the qualitative study of the subject, where astrophysics is used to describe its physics-oriented version.

Inevitably some topics, like Universe exploration, will also concern with Aerospace Engineering and its affinities.
