Galaxy clusters

Extreme Learning Machine (ELM) Extreme Learning Machine is a feedforward neural network for the regression, sparse approximation, feature learning, compression, clustering and for classification with a single or multi layers of hidden nodes in which the parameters are randomly generated and they are need not be changed. The hidden nodes are assigned randomly and are never updated. But they can be inherited from their ancestors. In many cases the output weights of hidden nodes are generally learned

Stars are phenomenal glowing spheres that everyone has noticed in the night sky. Long ago they were poorly understood. Today, with the help from astronomers, physicists, and other space scientists, we have discovered a large amount of information about stars. These huge balls of flaming gas have many different ranges of characteristics. We can observe the many fascinating colors that may be displayed from stars. Some of them are not stars themselves, but the trillions of fragments left behind

The Milky Way is flat and disk shaped collection of gas dust and stars. It is 100,000 light years across and 7,000 light years thick. The Milky Way’s dish has two major spiral arms and two minor ones that comes together in of the galaxy. In the center of the disk is a cylinder bar that has a collection of old red stars. The Milky Way is visible on a moonless night only if you are in very dark spot where you would see a faint fuzzy glow in the sky. If Sagittarius and Scorpius are visible you notice

help in a better understanding of this component which forms 26:8% of the entire universe. This report delves into the problems that led to the introduction of the concept of Dark Matter. The at Rotation Curve Problem of velocity distribution of galaxies and the Virial Problem have been discussed. The contribution of Dark Matter in the formation of Large Scale Structures have also been looked into. We have also attempted to give an idea about the probable number densities of three Dark Matter candidates

Hubble Space Telescope The Hubble Space Telescope is the first major telescope that was placed in space. It has been in operation for over twenty-five years, and has greatly changed our knowledge of the universe. It can observe galaxies and stars that are very far away since it is not blocked at all by light pollution and smog that obstructs the views of the telescopes on Earth. Hubble is fascinating because it was and still is the most revolutionary telescope since Galileo first looked through

unless more matter is present than can be seen. Most astrologists believe dark matter to be all over the universe and to have had a strong influence on its structure and evolution. The primary evidence for dark matter is that studies show that many galaxies such as our own would spread instead of rotating, or would not have formed or move as they do, if they did not contain

how galaxies within the vast expanse of the Universe have undergone dramatic trasnforsatioms over the last eight billion years ro so.

believe that it exist. Experiments and observations have been conducted to build evidence that dark matter exists. The information and explanations gathered present convincing evidence for dark matter. This evidence is found within the speed of galaxy

neighbors puts me in complete awe. It’s just exciting to me and its impressive how vast and unexplored the universe is. Astrophysics Is a branch of astronomy that is about the physics of everything of the universe, and heavenly bodies like galaxies, star clusters, etc. The job of the Astrophysics is to understand the universe. This occupation is constantly developing because every day we learn more and more about how the universe functions. Another objective of this job or occupation is to discover

This is because of the fact that it is very hard to detect and almost impossible to see. Although it is impossible to see, we can see the effects of them both in our galaxy. One way that we can “see” the dark matter is the movement of the Milky Way Galaxy. While studying the Milky Way, scientists noticed that the outer rings of the galaxy were moving at the same speed as the inner rings (“Dark Energy, Dark Matter”, n.d.) . This may seem normal, but, due to the law of gravity, the outer
