Deep space is defined by the United States government as all of outer space which lies further from Earth than a typical low-Earth-orbit, thus assigning the Moon to deep-space. [118] Other definitions vary the starting point of deep-space from, "That which lies beyond the orbit of the moon," to "That which lies beyond the farthest reaches of ...
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. Spaceflight. Human spaceflight
Space science is the study of everything in outer space. [26] This has sometimes been called astronomy , but recently astronomy has come to be regarded as a division of broader space science, which has grown to include other related fields, [ 27 ] such as studying issues related to space travel and space exploration (including space medicine ...
Space research is scientific study carried out in outer space, and by studying outer space. From the use of space technology to the observable universe , space research is a wide research field . Earth science , materials science , biology , medicine , and physics all apply to the space research environment.
The direction in space that is directly opposite the center of the Milky Way Galaxy, as viewed from Earth; considered as a point on the celestial sphere, the Milky Way's anticenter is in the constellation Auriga. Galactic Center The rotational center of the Milky Way galaxy, consisting of a supermassive black hole of 4.100 ± 0.034 million ...
In most industrial countries, the aerospace industry is a co-operation of the public and private sectors. For example, several states have a civilian space program funded by the government, such as National Aeronautics and Space Administration in the United States, European Space Agency in Europe, the Canadian Space Agency in Canada, Indian Space Research Organisation in India, Japan Aerospace ...
Space exploration is the use of astronomy and space technology to explore outer space. [1] While the exploration of space is currently carried out mainly by astronomers with telescopes , its physical exploration is conducted both by uncrewed robotic space probes and human spaceflight .
Planetary science is the study of the assemblage of planets, moons, dwarf planets, comets, asteroids, and other bodies orbiting the Sun, as well as extrasolar planets. The Solar System has been relatively well-studied, initially through telescopes and then later by spacecraft.
