WebThe answer is that because light travels at a finite speed, the light from some things that we see now left them millions of years ago. And because the Universe is expanding, light such as this is redshifted; the more redshift, the longer the light has traveled to reach us. By observing very high redshift objects, we can look back in time. http://www.astronomy.com/magazine/greatest-mysteries/2024/07/38-how-did-the-milky-way-galaxy-form WebTopics include the gravitational growth of perturbations in an expanding universe, the abundance and properties of dark matter halos and galaxies, reionization, the observational methods used to detect the earliest galaxies and probe the diffuse gas between them--and much more.

WebStars are fueled by the nuclear fusion of hydrogen to form helium deep in their interiors. The outflow of energy from the central regions of the star provides the pressure necessary to keep the star from collapsing under its own weight, and the energy by which it shines. WebWhen galaxies grew in the first billion years, light from their hot stars spread into the surrounding intergalactic gas, producing bubbles of ionized gas around them. As galaxies continued to grow, so did the ionized bubbles – reionizing all hydrogen.

The earliest stage in the evolution of galaxies is their formation. When a galaxy forms, it has a disk shape and is called a spiral galaxy due to spiral-like "arm" structures located on the disk. There are different theories on how these disk-like distributions of stars develop from a cloud of matter: however, at present, none of them exactly predicts the results of observation.
