Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos. It uses mathematics , physics , and chemistry in order to explain their origin and their overall evolution .
Nucleic acids may not be the only biomolecules in the universe capable of coding for life processes. [1]Astrobiology (also xenology or exobiology) is a scientific field within the life and environmental sciences that studies the origins, early evolution, distribution, and future of life in the universe by investigating its deterministic conditions and contingent events. [2]
The following outline is provided as an overview and topical guide to space science: Space science – field that encompasses all of the scientific disciplines that involve space exploration and study natural phenomena and physical bodies occurring in outer space, such as space medicine and astrobiology. [1] [2]
Astronomy – science of celestial bodies and their interactions in space. Its studies include the following: The life and characteristics of stars and galaxies; Origins of the universe. Physical science uses the Big Bang theory as the commonly accepted scientific theory of the origin of the universe. A heliocentric Solar System. Ancient ...
Astroecology also concerns wastage, such as the leakage of biological matter into space. This will cause an exponential decay of space-based biomass [2] [3] as given by Equation (2), where M (biomass 0) is the mass of the original biomass, k is its rate of decay (the fraction lost in a unit time) and biomass t is the remaining biomass after time t.
Bioastronautics is a specialty area of biological and astronautical research which encompasses numerous aspects of biological, behavioral, and medical concern governing humans and other living organisms in outer space; and includes the design of space vehicle payloads, space habitats, and life-support systems.
Astrophysics is a science that employs the methods and principles of physics and chemistry in the study of astronomical objects and phenomena. [1] [2] As one of the founders of the discipline, James Keeler, said, astrophysics "seeks to ascertain the nature of the heavenly bodies, rather than their positions or motions in space—what they are, rather than where they are", [3] which is studied ...
Analysis of planetary surfaces and surface features is a major component of planetary science. Planetary science (or more rarely, planetology) is the scientific study of planets (including Earth), celestial bodies (such as moons, asteroids, comets) and planetary systems (in particular those of the Solar System) and
