[[ගොනුව:Moon Dedal crater.jpg|thumb|Space missions have been used to image distant locations within the [[Solar System]], such as this ''[[Apollo 11]]'' view of [[Daedalus (crater)|Daedalus crater]] on the [[far side of the Moon]].]]

This discipline is the science of [[Astronomical object|celestial objects]] and [[phenomena]] that originate outside the [[Earth's atmosphere]]. It is concerned with the evolution, [[physics]], [[chemistry]], [[meteorology]], and [[motion (physics)|motion]] of celestial objects, as well as the [[physical cosmology|formation and development of the universe]]. Astronomy includes the examination, study and modeling of [[star]]s, [[planet]]s, [[comet]]s, [[galaxy|galaxies]] and the [[cosmos]]. Most of the information used by astronomers is gathered by remote observation, although some laboratory reproduction of celestial phenomenon has been performed (such as the molecular chemistry of the [[interstellar medium]].)

[[ගොනුව:DNA-fragment-3D-vdW.png|thumb|A fragment of [[DNA]], the chemical sequence that contains [[Genetics|genetic]] instructions for the [[Developmental biology|development]] and functioning of [[Life|living organisms]]]]

This field encompasses a set of disciplines that examines [[phenomenon|phenomena]] related to living organisms. The scale of study can range from sub-component [[biophysics]] up to complex [[ecology|ecologies]]. Biology is concerned with the [[characteristic]]s, [[scientific classification|classification]] and [[behaviors]] of [[organism]]s, as well as how [[species]] were formed and their interactions with each other and the [[environment (biophysical)|environment]].

Constituting the scientific study of matter at the [[atom]]ic and [[molecule|molecular]] scale, chemistry deals primarily with collections of atoms, such as [[gas]]es, molecules, [[crystal]]s, and [[metal]]s. The composition, statistical properties, transformations and reactions of these materials are studied. Chemistry also involves understanding the properties and interactions of individual atoms for use in larger-scale applications. Most chemical processes can be studied directly in a laboratory, using a series of (often well-tested) techniques for manipulating materials, as well as an understanding of the underlying processes. Chemistry is often called "[[the central science]]" because of its role in connecting the other natural sciences.

'''Earth science''' (also known as '''geoscience''', '''the geosciences''' or '''the Earth Sciences'''), is an all-embracing term for the sciences related to the planet [[Earth (planet)|Earth]], including [[geology]], [[geophysics]], [[hydrology]], [[meteorology]], [[physical geography]], [[oceanography]], and [[soil science]].

Physics embodies the study of the fundamental constituents of the [[universe]], the [[forces]] and interactions they exert on one another, and the results produced by these interactions. In general, physics is regarded as the fundamental science as all other natural sciences utilize and obey the principles and laws set down by the field. Physics relies heavily on [[mathematics]] as the logical framework for formulation and quantification of principles.
