Cosmos

September 25, 2025 - The cosmos (/ˈkɒzmɒs/, US also /-moʊs, -məs/; Ancient Greek: κόσμος, romanized: kósmos) is an alternative name for the universe or its nature or order. Usage of the word cosmos implies viewing the universe as a complex and orderly system or entity.

2 weeks ago - Cosmology (from Ancient Greek κόσμος (cosmos) 'the universe, the world' and λογία (logia) 'study of') is a branch of physics and metaphysics dealing with the nature of the universe, the cosmos. The term cosmology was first used in English in 1656 in Thomas Blount's Glossographia, ...

January 12, 2000 - Cosmos, in astronomy, the entire physical universe considered as a unified whole (from the Greek kosmos, meaning “order,” “harmony,” and “the world”). Humanity’s growing understanding of all the objects and phenomena within the ...

November 4, 2025 - Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos. It uses mathematics, physics, and chemistry to explain their origin and their overall evolution.

"Cosmos" in astronomy is the harmonious and orderly whole, a system that is governed not by human or supernatural laws but by natural law. In astronomy, cosmos refers to objects that exist naturally, especially those visible in the sky.

Cosmos is a unique astronomy reference written by research astronomers. Our encyclopedia entries are for a general audience who wish to know detailed information on a wide range of astronomical topics. Cosmos is an evolving resource, with new entries being added all the time.

May 11, 2025 - At the moment, more than 150 astronomers around the world actively contribute to the project. The project's primary goal is to study the relationship between large scale structure (LSS) in the universe and dark matter, the formation of galaxies, and nuclear activity in galaxies. This includes careful analysis of the dependence of galaxy evolution on environment. The survey covers a field, often known as the COSMOS ...

September 25, 2024 - The Cosmic Evolution Survey (COSMOS) was a wide field observational astronomy project. It was aimed at observing the correlation between galaxies, star formations, active galactic nuclei and dark matter and how they evolve, with large-scale ...

September 21, 2025 - This timeline of cosmological theories ... of the cosmos over the last two-plus millennia. Modern cosmological ideas follow the development of the scientific discipline of physical cosmology. For millennia, what today is known to be the Solar System was regarded as the contents of the "whole universe", so advances in the knowledge of both mostly paralleled. Clear distinction was not made until circa mid-17th century. See Timeline of Solar System astronomy for further ...

October 29, 2024 - Cosmos refers to all the universes or multiverse and to a world order perceived as harmonious. Cosmology is a science that has its object of inquiry the origins, development, and structure of all the universes as an integrated entity, also known ...

May 24, 2025 - This was precipitated by observations that established the size and the dynamics of the cosmos that could be explained by Albert Einstein's General Theory of Relativity. In its infancy, cosmology was a speculative science based on a very limited number of observations and characterized by a dispute between steady state theorists and promoters of Big Bang cosmology. It was not until the 1990s and beyond that the astronomical observations would be able to eliminate competing theories and drive the science to the "Golden Age of Cosmology" which was heralded by David Schramm at a National Academy of Sciences colloquium in 1992.

The Cosmological Evolution Survey (COSMOS) is an astronomical survey designed to probe the formation and evolution of galaxies as a function of both cosmic time (redshift) and the local galaxy environment.

August 19, 2025 - Just a few of the ideas explored in Cosmos include the history and mutual development of science and civilization, the nature of the Universe, human and robotic space exploration, the inner workings of the cell and the DNA that controls it, and the dangers and future implications of nuclear war.

Astronomical observatories are located worldwide and at various size scales, and the Astrophysics Data System is digitizing many of their historical publications. Observatories may also have publications online that can highlight what they work on. Historical observatory circulars are in the Yale Library catalog, too. Wikipedia has a non-sortable table of astronomy observatories.

October 2, 2025 - In the 1910s, Vesto Slipher (and later Carl Wilhelm Wirtz) interpreted the red shift of spiral nebulae as a Doppler shift that indicated they were receding from Earth. However, it is difficult to determine the distance to astronomical objects. One way is to compare the physical size of an object to its angular size, but a physical size must be assumed in order to do this.

February 28, 2008 - What are the hidden ingredients — dark matter and dark energy — that make up most of the universe but remain invisible to us? PhysCOS seeks to uncover these mysteries, helping us better understand the cosmos and our place within it. ... PhysCOS brings together physics and astronomy to explore some of the biggest mysteries of the universe.

March 20, 2025 - Following Sagan's death in 1996, his widow Ann Druyan, the co-creator of the original Cosmos series along with Steven Soter, and astrophysicist Neil deGrasse Tyson sought to create a new version of the series, aimed to appeal to as wide an audience as possible and not just to those interested in the sciences.
