The first stars to form in the universe were nothing like our sun. They were gigantic, massive blue stars that emitted high amounts of energy. All the matter in the early universe was primarily in the form of hydrogen and helium. It is unlikely that the first stars had any planets, as heavier elements are needed to form … Ver mais Even small galaxies have a strong gravitational pull, especially when compared to just stars or star clusters.

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. 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. Olin Eggen, Donald Lynden-Bell, and Allan Sandage in 1962, proposed a theory that disk galaxie…
