Galaxies, a surprise

The galaxies are a very large disciplined system bounded by gravitational force, which is composed of stars, interstellar gas and dust, plasma and abundant invisible objects. In a typical galaxy, there are 10 million

on to one trillion people who are all rolling around a common gravitational center. In addition to the isolated stars, there are galactic systems in the galaxy, they are stellar and various types of nebula. Most galaxies range from hundreds of light years to thousands of light years and distance between galaxies at a distance of million light-years.

About 90 percent of the galaxy is responsible for the mass, but the invisible object is very uncertain about their existence and structure.  Evidence of the existence of the largest black hole inside the galaxy has been found. Interstitial space is full of light plasma. There are more than 100 billion galaxies in our current range.

 

This galaxy was about 13,60,000,000 years old. There is a black hole called Sagittarius A in its center. Earth's distance from this center is about 26,000 light years. The nearest galaxy is - The Mortal Dwarf Galaxy ( Canis Major Dwarf, discovered in 2003). The galaxy's distance from its center is about 42,000 light years. And its distance from our solar system is about 25,000 light years. However, scientists consider this galaxy as a distant part of the galaxy.

Galaxies near the galaxy's Andromeda ( of Andromeda Galaxy (M31 ). This gyalaksitio galactic gravity bound by. For this reason, both the Galaxy to a local group  ( Local Group is ) part. The local team has galaxies, andromeda and more than 30 chotobara Galaxy.   Andromeda's distance from Earth is about 250,000,000 light years.

Stories about its origin and structure are varied in various legends. Philosophers such as Aristotle, Anaxagoras, Democritus, considered the galaxy as a gathering of stars. According to Purshish astronomer Abu Raihan al-Biruni, this galaxy was thought to be the sum of the numerous nebula. Galileo was able to give a very close conclusion about its actual condition with the help of his telescope.  

* Lightyears 

Light years is the distance that light travels in a year, the distance It is worth noting that the speed of light in one second is 3 lakh km. .
