Anthony Patrick Fairall
Anthony Patrick (Tony) Fairall (September 15, 1943 – November 22, 2008) was a South African astronomer most noted for his work on exploring the large-scale structure of the Universe, such as filaments and voids. He was the director of what is now the Iziko planetarium in Cape Town and was a well-known popularizer of astronomy in South Africa. Fairall was born in London and moved with his family to Johannesburg, South Africa, in 1948 and then Harare, Zimbabwe in 1953. He studied at the University of Cape Town, completing his undergraduate degree in 1966. He studied for his doctorate under Gerard de Vaucouleurs and Fritz Zwicky at the University of Texas at Austin The University of Texas at Austin (UT Austin, UT, or Texas) is a public research university in Austin, Texas. It was founded in 1883 and is the oldest institution in the University of Texas System. With 40,916 undergraduate students, 11,075 ..., receiving his degree in 1970.

South African People
The population of South Africa is about 58.8 million people of diverse origins, cultures, Languages of South Africa, languages, and Religion in South Africa, religions. The South African National Census of 2022 was the most recent census held; the next will be in 2032. In 2011, Statistics South Africa counted 2.1 million foreigners in total. Reports suggest that is an underestimation. The real figure may be as high as five million, including some three million Demographics of Zimbabwe, Zimbabweans.

Astronomer
An astronomer is a scientist in the field of astronomy who focuses their studies on a specific question or field outside the scope of Earth. They observe astronomical objects such as stars, planets, natural satellite, moons, comets and galaxy, galaxies – in either observational astronomy, observational (by analyzing the data) or theoretical astronomy. Examples of topics or fields astronomers study include planetary science, Sun, solar astronomy, the Star formation, origin or stellar evolution, evolution of stars, or the galaxy formation and evolution, formation of galaxies. A related but distinct subject is physical cosmology, which studies the Universe as a whole. Types Astronomers usually fall under either of two main types: observational astronomy, observational and theoretical astronomy, theoretical. Observational astronomers make direct observations of Astronomical object, celestial objects and analyze the data. In contrast, theoretical astronomers create and investigate C ...

Large-scale Structure Of The Universe
The observable universe is a ball-shaped region of the universe comprising all matter that can be observed from Earth or its space-based telescopes and exploratory probes at the present time, because the electromagnetic radiation from these objects has had time to reach the Solar System and Earth since the beginning of the cosmological expansion. There may be 2 trillion galaxies in the observable universe, although that number was reduced in 2021 to only several hundred billion based on data from ''New Horizons''. Assuming the universe is isotropic, the distance to the edge of the observable universe is roughly the same in every direction. That is, the observable universe is a spherical region centered on the observer and is unique for every unique observational position. The word ''observable'' in this sense does not refer to the capability of modern technology to detect light or other information from an object, or whether there is anything to be detected. It refers to the ph ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
