Trouvelot, The great nebula in Orion (1875).. Astronomical art is a genre of space art that focuses on visual representations of outer space.It encompasses various themes, including the space environment as a new frontier for humanity, depictions of alien worlds, representations of extreme phenomena like black holes, and artistic concepts inspired by astronomy.
This glossary of astronomy is a list of definitions of terms and concepts relevant to astronomy and cosmology, their sub-disciplines, and related fields. Astronomy is concerned with the study of celestial objects and phenomena that originate outside the atmosphere of Earth. The field of astronomy features an extensive vocabulary and a ...
IfA: either Institute for Astronomy (Hawaii) or Institute for Astronomy, School of Physics and Astronomy, University of Edinburgh, Scotland IFN – ( celestial object ) integrated flux nebulae, dust and gas outside the plane of the Milky Way, which are thus illuminated by the entire galaxy as opposed to a nearby star or stars
The most striking aspect is that it requires a different definition of what it means to be a void. Instead of the general notion that a void is a region of space with a low cosmic mean density; a hole in the distribution of galaxies, it defines voids to be regions in which matter is escaping; which corresponds to the dark energy equation of ...
Astrophysics is the branch of astronomy that employs the principles of physics and chemistry "to ascertain the nature of the astronomical objects, rather than their positions or motions in space". [ 74 ] [ 75 ] Among the objects studied are the Sun , other stars , galaxies , extrasolar planets , the interstellar medium and the cosmic microwave ...
Physical cosmology is a sub-branch of astronomy that is concerned with the universe as a whole. Modern physical cosmology is dominated by the Big Bang Theory which attempts to bring together observational astronomy and particle physics ; [ 5 ] [ 6 ] more specifically, a standard parameterization of the Big Bang with dark matter and dark energy ...
