NAME

Astronomy and astrophysics

DESCRIPTION

Astronomy and astrophysics are the study of objects and phenomena that are found beyond our solar system. This combines theoretical simulations and observation with both terrestrial and space-craft-borne instruments of the electromagnetic radiation and high-energy particles emitted by celestial bodies.

58 skos:definition Computational astrophysics is the study of the phenomena that occur in space using computer simulations. This can involve modelling processes that take place over millions of years, such as colliding galaxies or the slow destruction of a star by a black hole. This also includes understanding the high-energy phenomena that take place in stars.

66 skos:definition Cosmology is the study of the universe; its birth, evolution, and ultimate fate. This includes further developing and refining the prevailing model, the Big Bang theory, investigating the universe’s rate of expansion, and measuring radiation left over from the Big Bang, the so-called cosmic microwave background.

76 skos:definition Exoplanets are the celestial bodies orbiting stars other than our Sun. Their small size makes them difficult to detect from Earth, particularly as they appear much dimmer than their parent stars. So indirect methods are employed, such as observing changes in starlight as a result of the exoplanet and its motion.

86 skos:definition Galaxies and clusters are the ensembles of stars and other astronomical objects bound together by gravitational forces. Galaxies are ordered into galaxy groups, which are in turn organised into clusters. The Earth is in a galaxy called the Milky Way, which is in the Local Group in the Virgo Supercluster.

94 skos:definition High-energy astrophysics is the study of the processes that occur within stars, black holes and supernovae. These processes can be monitored by measuring the high-energy electromagnetic radiation and particles that they emit including x-rays, ultraviolet light and gamma rays. These observations are supplemented with computer simulations.

112 skos:definition Particle astrophysics is the study of fundamental particles travelling through space, particularly those that reach the Earth. These cosmic rays include photons, protons, alpha particles and neutrinos. Some of these decay to other particles in the atmosphere, while neutrinos can pass through the entire Earth without being absorbed.

Central to physics are ideas such as energy, mass, particles and waves. Physics attempts to both answer philosophical questions about the nature of the universe and provide solutions to technological problems.
