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 cosmic system is explained in the article universe.
The origin, evolution, and nature of the universe have fascinated and confounded humankind for centuries. New ideas and major discoveries made during the 20th century transformed cosmology – the term for the way we conceptualize and study the universe – although much remains unknown.

Jun 28, 2024 · Cosmology, the field of study that brings together the natural sciences, particularly astronomy and physics, in a joint effort to understand the physical universe as a unified whole. When the universe is viewed in the large, a dramatic new feature, not present on small scales, emerges—the cosmological expansion.
Hosted by renowned astrophysicist Neil deGrasse Tyson, COSMOS will explore how we discovered the laws of nature and found our coordinates in space and time. ...
How does the universe work? There are many mysteries of the universe we have yet to understand. Since the early 20 th century, scientists have known that the universe is expanding. In the 1990s, researchers discovered that, surprisingly, the expansion is accelerating.
6 days ago · Cosmology is the scientific study of the universe as a unified whole, from its earliest moments through its evolution to its ultimate fate. The currently accepted cosmological model is the big bang. In this picture, the expansion of the universe started in an intense explosion 13.8 billion years ago.
Cosmology. What is the universe made of? How did it begin? How has it evolved over the 13.8 billion years since its origin? And how will it end? These are the questions addressed by cosmology, the study of the universe as a whole.
Sep 1, 2020 · Now we can confidently trace cosmic history back 13.8 billion years to a moment only a billionth of a second after the big bang. Astronomers have pinned down our universe's expansion rate, the...
