Space physics. Space physics, also known as space plasma physics, is the study of naturally occurring plasmas within Earth's upper atmosphere and the rest of the Solar System. It includes the topics of aeronomy, aurorae, planetary ionospheres and magnetospheres, radiation belts, and space weather (collectively known as solar-terrestrial physics ...
The universe is all of space and time [ a ] and their contents. [ 10 ] It comprises all of existence, any fundamental interaction, physical process and physical constant, and therefore all forms of matter and energy, and the structures they form, from sub-atomic particles to entire galactic filaments.
Space exploration, like its classical form astronomy, is one of the main sources for space science. While the observation of objects in space, known as astronomy , predates reliable recorded history , it was the development of large and relatively efficient rockets during the mid-twentieth century that allowed physical space exploration to ...
This is an accepted version of this page This is the latest accepted revision, reviewed on 23 September 2024. Discrepancy between lack of evidence of advanced alien life and apparently high likelihood it exists This article is about the absence of clear evidence of extraterrestrial life. For a type of estimation problem, see Fermi problem. Enrico Fermi (Los Alamos 1945) The Fermi paradox is ...
The science and engineering of spacefaring and spaceflight, a subset of Aerospace engineering (which includes atmospheric flight) Space technology is technology for use in outer space, in travel or other activities beyond Earth's atmosphere, for purposes such as spaceflight, space exploration, and Earth observation.
The International Space Station is a platform for scientific research that requires one or more of the unusual conditions present in low Earth orbit (for example microgravity, (cosmic) - radiation and extreme temperatures). The primary fields of research include human research, space medicine, life sciences, physical sciences, astronomy and ...
Space agencies, governments, researchers and commentators have isolated a large number of direct and indirect benefits of space exploration programs including: New technologies that can be utilized in other industries and society (such as the development of communications satellites) Improved knowledge of space and the origin of the universe.
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.
