Galaxy clusters

they can confirm that it is affecting the shape and structure of galaxies in the universe. Observations of luminous matter in the universe show that it clumps together to form galaxies. However, there isn’t enough luminous matter to gravitationally keep itself together. This is how scientists confirm dark matter exists, by seeing how it keeps regular matter together through gravity (Basulto). Currently, physicists know that galaxies form around dark matter halos. When dark matter was created at the

Life’s Meaning is What You Make It Friday, January 27, 2017. This was the night I formulated the answer to the great question that humans have been contemplating since our existence, “Are We Significant in the Universe?” After visiting the planetarium show at the University of Central Arkansas, I felt like I had it all figured out. Seeing the vast universe, or just the small amount that we have actually discovered, puts things into perspective about just how small the Earth is and how far away everything

the remains of a dwarf spheroidal galaxy that is in the process of merging with the Milky Way. It is the largest galaxy visible from the Earth, in terms of the area of the night sky covered. The stream covers over 100 square degrees, and possibly as much as 1,000 square degrees. Despite its proximity to the solar system and the solid angle that it consequently covers, the stream contains only a few hundred thousand stars. The low surface brightness of the galaxy may have militated against its detection

determine why it exists at all (Hawking). To accomplish this goal, he creates a theory that explains the origin of the universe and the steps leading to the formation of the elements. The universe is about 14 billion years old and consists of many clusters that has approximately 400 billion stars. In fact, the Earth and everything around us are made by stars (Hawking). The Big Bang Theory is used to tell how the universe and earth was created. The universe started with a small-hot ball of energy,

1. What prominent northern hemisphere star was the first to have its spectrum photographed? 2. An interstellar cloud of gas known as an H-II region is mainly composed of what? 3. What celestial object is known as the morning star or the evening star depending on when it is seen in the sky? 4. Which planet of the Solar System is accompanied by two moons named for the Greek gods of fear and terror? 5. On what kind of diagram are stars plotted according to their surface temperature

star makes can be used to find the distance of the star through the help of trigonometry. Main sequence fitting: Main sequence fitting method is used to find the distance of the clusters of the stars. Clusters is group of stars which are next to each other. This process works by finding the apparent magnitude of the cluster from the earth. Then, we find the distance of the exact distance through the help of parallax methods. This distance of the

For my observing project I chose to do Messier 98 (M98). I chose M98 because I am absolutely fascinated by galaxies, and I think spiral galaxies look the coolest. M98 is located in the constellation Coma Berenices and it is in the Virgo Cluster of galaxies. A French astronomer, named Pierre Mechain, on March 15th 1781, discovered M98 and then Charles Messier measured its position and catalogued it on April 13, 1781. M98, also known as NGC 4192, is located at a Right Ascension of 12h 13m 48s and at

a tiny planet located in a solar system of millions in a galaxy of many more in the universe. A galaxy, also called a nebula, consists of billions of stars, interstellar gas, dust, and dark matter which are all bound to form a massive cloud in which we live in. Although it cannot be very well explained, dark matter makes up at least 90% of a galaxy’s mass.

hath made the earth by his power, he hath established the world by his wisdom, and hath stretched out the heavens by his discretion”. Jeremiah 10:12. Most astronomers agree the universe is expanding because the clusters of galaxies are moving farther away from other clusters in the galaxy. Olbers’s Paradox is the idea that faraway stars appear fainter than those nearby:, and the entire sky should be as brilliant as the surface of the Sun. This means “either the universe is finite in extent, or

“Nebulae” inside the Milky Way Galaxy or separate, distant Galaxies? Discoveries of what were termed “nebulae” began in the early 17th century. The first of these discoveries was the Orion Nebula, which looked like a normal star to the naked eye. French scholar Peiresc discovered it in 1610 using one of the first telescopes to be made. Later, in 1656, Christiaan Huygens observed the interior of the Orion Nebula and determined that it consisted of a compact quadruple star system instead of a singular
