Most astronomers believe that all galaxies formed during the origin of the universe, the big bang. Helium and hydrogen atoms were created along with other element particles. The atoms were magnetically attracted or collided with others, cre...

I am sixth grader and I am doing a science project on galaxies. I wanted to know how galaxies are formed. As you may know, galaxies are mainly of two kinds: spiral galaxies and elliptical galaxies (there are also irregular galaxies). Spiral...

Computer simulations show us that the big elliptical galaxies can form from the collisions of galaxies, including spiral galaxies. Elliptical galaxies formed in this way have faint shells of stars or dense clumps of stars that are probably debris left from the merging process.

For a long time, two different types of models of galaxy formation were common: First, "top-down" theories according to which galaxies have formed during a comparatively short period, at about the same time, within the first billion years after the universe started to expand, from an initial hot state, such as the...

Astronomers push the limits of techonolgy to peer back in time and pinpoint how quickly large galaxies formed. ... The first bright galaxies in the universe apparently formed very rapidly, jumping from just one or so in number to hundreds in the span of little over 1 percent of the universe's age, astronomers find.

The first cluster, a massive collection of possibly thousands of faint galaxies, formed when the universe was only five billion years old, about a third its current age, researchers said. Current estimates place the age of the universe at about 13.7 billion years old.

Surrey, UK (SPX) Feb 20, 2006 - British researchers said Sunday they have found the first observational evidence of how massive galaxies formed in the universe. ... The results: Massive galaxies neither formed rapidly, within a few million years after the Big Bang, nor gradually, over an extended period of time.

An important fact that should be mentioned before the question is answered is that all galaxies formed at approximately the same time i.e 13 Billion years ago. The classical model of galactic formation states that galaxies formed from the c...
