Cosmology - Page 4

Cosmology is the scientific study of the origin, evolution, structure, and eventual fate of the universe. It encompasses the examination of celestial bodies, cosmological phenomena, and the laws of physics that govern the cosmos. Cosmology seeks to understand the large-scale properties of the universe as a whole, including the dynamics of galaxies, the nature of dark matter and dark energy, and the concepts of time and space. It combines elements of astronomy, physics, and mathematics to address fundamental questions about the universe's beginnings, such as the Big Bang theory, and its ultimate future. Cosmologists analyze observational data from telescopes, satellites, and other instruments to develop theoretical models and simulations that explain the universe's behavior and characteristics.

Cosmic Fireworks: James Webb Telescope Captures the Explosive Heart of Our Galaxy

The James Webb Space Telescope (JWST) observed the area around Sagittarius A, our galaxy’s central black hole, 26,000 light-years away. JWST’s near-infrared camera revealed two types of flares from the black hole’s accretion disk: faint bursts and powerful, dramatic flares. These observations
