Galaxy

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.

In galaxy J0230 the disk of debris around the black hole in the center spins very, very fast. The black hole has as much mass as 2.2 billion suns The disk debris is mostly made of gas from surrounding nebulae. The gas orbits the supermassive black hole at around a fifth of light speed. That is around 125 million miles per hour or 200kph. The disk of gas around the black hole is propelled by the radiation emitted by the disk itself. The disk emits radiation because of the friction and gravity

What are Galaxies? You have probably heard about galaxies, whether it was in school, a book, a television show, or movie, you've most likely heard about them. If you're wondering, "what exactly are galaxies?" fret not, friend, for I will help you figure out this question. Let's start with some history. In 5th century, BC, someone named Democritus had the idea that the bright band in the sky(known as the Milky Way) may be composed of stars. In 4th century BC, Aristotle had the similar idea: "the

"starburst galaxies." Galaxies in general are basically billions of large independent groups of stars that exist in the universe. What sets a starburst galaxy apart from a regular galaxy is the fact that starburst galaxies have an exceptionally high rate of star formation inside of it. Some of these galaxies are so active that they are forming thousands of new stars every year, compared to the Milky Way producing about one star per year. This furious formation of stars typically happens when galaxies are

mergers, however, are not the only “flavor” of galaxy collisions. Nowadays, ma- jor mergers are considered to be mergers of galaxies with mass ratios of ∼ (1 − 4.5) : 1. Galaxy mergers with mass ratios of ∼ (1 − 2) : 1 can directly produce slowly rotating el- liptical galaxies, i.e. systems which are mostly random motion pressure supported, while mergers with mass ratios of ∼ (3 − 4.5) : 1 will, likely, result in disky, rapidly rotating ellipti- cal galaxies (e.g. Naab and Burkert, 2003; Bournaud et al

The next variable fp can be specified through the documentation and discovery of planets in our galaxy. We have been able to determine through both observational techniques that nearly all planets in our galaxy are 1, 2, or 3 times the mass of earth also known as super earths, and occur at an incredibly frequent rate. In fact, these super-earths are so frequent that each size has a third of a chance to be orbiting a star. With all three sizes considered there must be at least one earth or super-earth

including an immense amount of jargon, models, evidence, and observations. An inspection of an article entitled “The Current Status of Galaxy Formation,” written by Joseph Silk and Gary Mamon and published in Research in Astronomy and Astrophysics (RAA), demonstrates these qualities in abundance and goes beyond them into the realm of how the research involving galaxy formation will change in the future. The exigence or urgency of this article is never explicitly stated, but it can be garnered from

#38 The Milky Way Galaxy is made up of stars, nebulae, stellar stars and supernovas. In The early 20th Century, astronomers were trying to figure out what the faint fizzy objects in the sky they had a variety of different shapes. Some were elongated, round and some has spiral arms. Looking at the sky with a telescope the objects looks smokey and got their name “?Nebulae”. Astronomers couldn't quite understand how they formed and began doing research, later discovering what the objects are. In

What: How do galaxies affect us? Answer: We live in our galaxy called the Milky Way. It is called this because early human civilizations thought it looked like a giant milky swirl in the night sky. The closest galaxy to the Milky Way, the Andromeda galaxy, is said to have a strong gravitational pull with the Milky Way, and will eventually collide, which may or may not destroy everything in both galaxies. (Most likely will.) The collision could create a black hole, destroying everything once the
