Cosmology is a subfield of astrophysics that deals with the universe on very large scales.
There is also some crossover with particle physics for those who work on the very early universe..
The information, or data, about our universe measured by the instruments aboard satellites are transferred to the ground and analyzed by scientists.
The data can arrive in many forms and much processing is usually required before it can be used to "do science"..
Astrophysics and Cosmology involve the study of the physical processes that govern the behavior of astronomical objects, and the study of the origin, evolution, composition, and fate of the Universe as a whole..
Oct. 19, 2023 — Researchers have shown it's theoretically possible for black holes to exist in perfectly balanced pairs -- held in equilibrium by a cosmological force -- mimicking a single black Oct. 19, 2023 — An international team has spotted a remote blast of cosmic radio waves lasting less than a millisecond..
Astrophysics creates physical theories of small to medium-size objects and structures in the universe.
Astronomy measures the positions, luminosities, motions and other characteristics of celestial objects.
Cosmology covers the cosmos' largest structures and the universe as a whole..
The easiest to decode is that Cosmology studies universe as a whole and its phenomena at largest scales unlike Astronomy/Astrophysics, which study individual objects.
And then, Astronomy is primarily concerned with observing and measuring the relative positions and paths than giving explanations..
This dilemma exists largely because current cosmological observations simply disagree on how matter is distributed in the present-day universe
Of some help could be a new computer simulation that traces how all elements of the universe — ordinary matter, dark matter and dark energy — evolve according to the laws of physics
The development of cosmic structure – the huge strands of galaxies and caverns of emptiness that make up our universe – seems to be slowing down more than expected
That could mean there is something wrong with our understanding of the universe
The breathtaking visuals virtually show galaxies, and clusters of galaxies, manifesting in the universe, fed by the so-called cosmic web
This web is the largest structure in the universe, built with filaments made up of both normal matter, or baryonic matter, and dark matter
