Galaxies in Our Universe

Introduction The universe is a gathering of millions of galaxies that transcend human imagination. After the Big Bang, the universe was found to be composed of radiation and elementary particles. The information after the Big Bang shows how the galaxies are formed, whether small particles fuse together to eventually form galaxies, or the universe is systematically converted to gigantic galaxies (Nasa World book, 2013). The Milky Way is attracted by charm in the empty space filled with dust, gas (mainly 75% hydrogen and 25% helium), atoms, about 100 - 20 billion stars, interstellar clouds and planets I will.

Well, remember that there are (at least) 2 trillion galaxies in the universe. Our universe is very big, but our experience is all limited to this small planet. For us, space exploration is always remembrance, eternal determination We always have more questions than answers, but if good people work together for a common goal, we think You can achieve more than you can. When I saw the night sky more, I saw the reasons to focus on jobs that cultivate curiosity, seeking knowledge, and positive effects that will not disappear in the future.

Explanation: How is a galaxy formed in the early universe? To help find the answer, the astronomer Chile 's super - telescope array explored the dark night sky to find and calculate the galaxies formed when the universe was very young. Analysis of the distribution of several distant galaxies (near the red shift of 2.5) reveals huge clusters of galaxies over 300 million light-years, including 5000 times the mass of our Milky Way . Known as Hyperion, it is the largest and largest original supercluster currently found in the early universe. The original super cluster is a group of young galaxies collapsing under gravity to form a super clustered group and itself is a group of several galaxies and is itself a collection of numbers . 1 billion stars. In feature visualization, large numbers of galaxies are drawn in white and areas with many small galaxies are shown with blue shadows.

The billions of galaxies filled with the universe can be broadly divided into medium disk like our Milky Way and huge elliptical galaxies, usually with a mass of more than 10 times the star mass. By comparing distant galaxies, these galaxies appear long in the past, and as nearby galaxies get closer, they are observed to look like they are close to the present, and astronomers can observe these types of galaxies over time How can we investigate Evolution To compare these observations we have developed a theoretical model to predict the formation of a hierarchical galaxy - gravity collects substances to form stars and the solar system I will. However, part of the universe is not suitable for existing models. The largest galaxy was once the most active galaxy in star formation, but dormant, old older stars not replaced are died. In 2004, Professor Scannapieco and his team began to judge why it did.
