[2] Satellite geomorphology: What is the origin of the chain of high mountains that closely follows the equator of Saturn's moon, Iapetus? Are the mountains the remnant of hot and fast-rotating young Iapetus? Are the mountains the result of material (either from the rings of Saturn or its ring) that over time collected upon the surface?

The subdisciplines of theoretical astrophysics are: Compact objects – this subdiscipline studies very dense matter in white dwarfs and neutron stars and their effects on environments including accretion. Physical cosmology – origin and evolution of the universe as a whole. The study of cosmology is theoretical astrophysics at its largest scale.
Hugh Norman Ross (born July 24, 1945) is a Canadian astrophysicist, Christian apologist, and old-Earth creationist.. Ross obtained his Ph.D. in astronomy from the University of Toronto [1] [2] [3] and his B.Sc. degree in physics from the University of British Columbia. [4]
John R. Gribbin (born 19 March 1946) [1] is a British science writer, an astrophysicist, and a visiting fellow in astronomy at the University of Sussex. [2] His writings include quantum physics, human evolution, climate change, global warming, the origins of the universe, and biographies of famous scientists. He also writes science fiction.
[2] [3] The discovery (by chance in 1965) of the cosmic background radiation suggests that the early universe was dominated by a radiation field, a field of extremely high temperature and pressure. [4] There is background radiation observed across all wavelength regimes, peaking in microwave, but also notable in infrared and X-ray regimes.
Astrophysics is a science that employs the methods and principles of physics and chemistry in the study of astronomical objects and phenomena. [1] [2] As one of the founders of the discipline, James Keeler, said, astrophysics "seeks to ascertain the nature of the heavenly bodies, rather than their positions or motions in space—what they are, rather than where they are", [3] which is studied ...
A Different Universe: Reinventing Physics from the Bottom Down [1] is a 2005 physics book by Robert B. Laughlin, a winner of the Nobel Prize in Physics for the fractional quantum Hall effect. Its title is a play on the P. W. Anderson manifesto More is Different [ citation needed ] (historically important in claiming that condensed-matter ...
As an offshoot of the disciplines of astronomy and chemistry, the history of astrochemistry is founded upon the shared history of the two fields. The development of advanced observational and experimental spectroscopy has allowed for the detection of an ever-increasing array of molecules within solar systems and the surrounding interstellar medium.
