Galaxies came to fruition as meager as one billion years after the Big Bang, which most likely occurred around 13 billion to 14 billion years prior. There are two driving hypotheses to clarify how the primary galaxies shaped. Reality may include a touch of both thoughts.
One says that galaxies were born when huge billows of gas and dust fell under their own particular gravitational force, enabling stars to shape.
The other, which has picked up quality lately, says the youthful universe contained some little "clumps" of matter, which bunched together to frame systems. The vast majority of the early substantial cosmic systems were spirals. Be that as it may, after some time, many spirals converged to shape ellipticals.
The galaxy formation process has not halted. Our universe keeps on developing. Little systems are every now and again eaten up by bigger ones. The Milky Way may contain the remaining parts of a few littler systems that it has gulped amid its long lifetime. The Milky Way is processing no less than two little systems even now and may pull in others throughout the following couple of billion years.

Observations by Hubble Space Telescope and ground-based instruments show that the first galaxies took shape as little as one billion years after the Big Bang, which took place about 13 billion to 14 billion years ago. There are two leading theories to explain how the first galaxies were formed. The truth may involve a bit in both the theories.
The first theory says that galaxies were formed when vast amount of clouds of gases and dust collapsed under their own gravitational pull, allowing stars to form.
The other theory, which has gained strength in recent years, says that the young universe contains many small lumps of matter, which clumped together to form galaxies. Hubble Space Telescope has photographed many such lumps, which may be the precursors to modern galaxies. According to this theories, most of the early large galaxies were spiral. But over time, many spiral galaxies merged to form elliptical galaxies.
The galaxy-formation has not stopped yet. Our universe continues to evolve. Small galaxies are frequently gobbled up by large ones. The Milky Way may contain the remains of several small galaxies that it has swallowed during its long lifetime.
