Galaxies formed from dust, matter, and energy that formed from the explosion of the universe.
Big Bang, formation of galaxies, formation of sun, formation of earth.
Starburst Galaxies
Gravity is the primary force involved in the formation of galaxies after the big bang. Over time, the gravitational attraction between matter caused it to clump together, forming structures like galaxies and clusters of galaxies.
Spiral Galaxies
Collisions or interactions between galaxies are believed to be the cosmic accidents that can lead to the formation of many irregularly shaped galaxies. These interactions can trigger bursts of star formation and distort the shape of galaxies, resulting in the formation of irregular shapes.
Particles in the universe, such as hydrogen and helium, play a crucial role in the formation and evolution of galaxies. These particles come together through gravity to form stars, which then group together to create galaxies. The interactions and movements of these particles shape the structure and behavior of galaxies over time.
About the only thing that can surround galaxies is other galaxies. Since many galaxies appear to lie in approximate lines, one thing that influences galaxy formation may be "superstrings," but these have yet to be directly detected.
Elliptical galaxies are massive blobs of stars characterized by their round or ellipsoidal shapes. These galaxies are composed mainly of older stars and have little to no ongoing star formation activity.
While spiral galaxies are bright, elliptical galaxies are dim. Spiral galaxies are hotbeds of star formation, but elliptical galaxies aren't nearly as prolific because they contain less gas and dust, which means fewer new (and brighter) stars are born
Dwarf galaxies are smaller and fainter than other types of galaxies. They typically contain fewer stars and have lower luminosity compared to larger galaxies like spiral or elliptical galaxies. Despite their size, dwarf galaxies can be important for understanding galaxy formation and evolution, often serving as satellites to larger galaxies.
Scientists believe that galaxies formed earlier in the universe's history, with the most distant galaxies being some of the first to have formed after the Big Bang. Studying these distant galaxies can provide insights into the early stages of galaxy formation and evolution.
Scientists study distant galaxies to understand the formation, evolution, and properties of galaxies over time. By observing galaxies that are far away, they can explore the universe at different epochs and gain insights into how galaxies have changed and evolved since the early universe. Studying distant galaxies also helps scientists refine theories about the laws of physics and the nature of the universe as a whole.
