Milky Way: Galaxies Organized And Distributed Within The Universe

410 Words2 Pages

1. Describe the Milky Way. What does it contain? The Milky Way Galaxy is a gigantic and it is where Earth is located. It has a halo, however that you can’t really see it. It has over 200 billion stars it’s quite dusty and gassy. It is spiral galaxy.
2. How are galaxies organized and distributed within the universe?
Galaxies are distributed randomly within the universe, however are grouped together with the help of gravity.
3. How is gravity important to the galaxies within our universe?
Gravity holds galaxies together. The motion of all the material in the Universe is affected by gravity. Gravity helps the galaxies rotate and the planets in the solar systems orbit.
4. How do galaxies vary? Galaxies vary based on size, composition, and structure, however most all of them are arranged in clusters. The majority of galaxies are one of three major classes: spirals, …show more content…

How are galaxies created?
Some people believe that shortly after the big bang collapsing gas and dust clouds might have lead to the formation of galaxies. Galaxies form only a few hundred million years after the Universe was created.
3. How was Hubble important to our understanding of galaxies?
He was first to prove the expansion of universe and he classified galaxies. He is also known for providing evidence there were actually galaxies beyond the Milky Way.

4. How does the Milky Way compare with other galaxies within the universe?
It’s a spiral galaxy of the larger sort and middle aged compared to other galaxies. There are many galaxies in the Universe that are much bigger and older than the Milky Way.

5. How do gravity and dark matter shape the galaxies and affect their environment?
Many people think that dark matter may make galaxies rotate faster. Gravity pulls gas and dark matter together. No one knows what the dark matter really is though. People can see the effect gravity by watching the movement on stars and light that move through space, but no one has been able to actually see

Intro Galaxies have a variety of shapes that ranges from ellipsoids to spiral galaxies. Spiral galaxies are made up of many individual stars. Moreover, the components of the spiral galaxies move relative to each other. For instance, a rotation curve of a rigid body measures the speed and the radius.

This goes hand in hand with Newton's Laws of motion and universal gravitation. Newton's law of universal gravitation states that a particle attracts every other particle in the universe using a gravitational force and Newton's law of motion states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. Newton's Laws back up Kepler's laws by explaining how the planets orbit is an ellipse with the Sun at one of the two foci or center. The force that allows this to happen to the planets are explained by Newton's law and that the gravitational force is moving the planets into rotation, as by the law of motion. These forces assisting each other can make phenomenon's occur such as tides.

Argumentative essay Jaden Rodriguez Skyview Academy Abstract Today I am going to be talking about how important it is to have the necessary resources to understand astronomy, also why in my opinion, why Orion is the best star to observe for the first time and how cultural significance is so important in today. This essay argues that Orion should be observed with the necessary equipment like telescopes. I will also dwell into why Orion can just be beneficial beyond astronomy and also why telescopes are such a commodity in today's age. Cultural significance in ancient Egyptian mythology Orion was associated with Osiris the god of the afterlife, To add to all that the three stars forming Orion's belt were likely to be the three pyramids of Gyzia

International Dark-Sky Association reports, “The sky glow of Los Angeles is visible from an airplane 200 miles away. Residents of L.A. haven’t been able to see the stars for a while. In fact some city dwellers don’t even know what a natural night sky looks like. When a 1994 earthquake knocked out the city’s power, many anxious residents called local emergency centers to report a strange “giant, silvery cloud” in the dark sky. What they were seeing – for the first time – was the Milky Way, long obscured by light pollution.”

Kimmerer points out that “Like Creation stories everywhere, cosmologies are a source of identity and orientation to the world. They tell us who we are. We are inevitably shaped by them no matter how distant they may be from our consciousness” (Skywoman Falling). This led me to conclude that creation stories are a crucial part of our life. They give us purpose, meaning, and a knowledge of why we've been placed here on earth.

But when the twentieth century was at the gates of new and historical events, that began to change. New discoveries shook the old certainties and paved away for questions about "where the universe came from?". One observation transformed our ideas about the true scale of the universe. It began with a mystery in the sky. By the early part of the twentieth century, it was well known that our solar system lay within a galaxy, the milky way.

Dark matter is just what it’s name suggests; a complete mystery. More is unknown than is known about dark matter, though it is said to make up more than 27% of the universe. The existence of dark matter has only been inferred from the gravitational effect it appears to have on normal matter. Scientists are led to believe that dark matter does not interact with the electromagnetic force since zero light can be reflected, emitted or absorbed, which in turn makes it nearly impossible to detect.

According to modern considerations, neutron star, it is star in the final stage of its evolution, which has no internal energy sources and consist mainly of neutrons in a state of Fermi gas with a small admixture of other particles. So, neutron stars - one of the most interesting stars in the Universe. First of all, they are the most compact stars whose masses range from 1,44 (Chandrasekhar limit) to 2 solar masses, despite the fact that they are extremely small radii, from 6 to 18 km. This value corresponds to the mass and radius of the enormous gravitational energy and gravitational acceleration on the surface.

The stars shine bright on the vast stage of the galaxy. The awe-inspiring constellations have shifted and torn, casting stars light-years from their position, giving each a dancing partner. Each star compliments their companion and each shine brighter than they could have alone. The stars twinkle softly and watch me watching them. I wish to teach them, for I have lived a long, prosperous life and I know I can teach them so much.

If you use something in the universe, such as a star, you can attempt to follow the causes of each effect. The star is an effect of a high concentration of interstellar gas and dust in an extremely cold region of space. The next question is, where does interstellar gas and dust come from? Interstellar gas is formed from molecular gas, which was formed by a theorized concept, called the ‘big bang theory’. The big bang was an enormous blast of energy throughout the universe, which formed all things instead the universe.

Gravity has impacted our solar systems in many ways from shaping it’s formation, the motion of each planet, asteroid, and other celestial object’s orbits, and is in fact the glue that holds it together all of this together -- Knowing this has helped many scientists in the past and it will in future discoveries and observations. As said before gravity has impacted the formation of our solar system and with the given evidence I will say how. Gravity in many ways has shaped and formed our solar system. An example would be the shape of the solar system’s celestial bodies’ orbit. They are in a circular orbit (though the sun is not in the center making it look a bit elliptical) and this is because of the sun’s gravitational force pulling on each

All these elements were combined together to create an impressive teaching tool allowing people to acquire the skills they needed to survive. COSMIC DANCES The movement of the celestial bodies themselves, such as the stars and the moon, and the way they interact with each other, in an observable way; have long been referred to as a cosmic dance. It is documented that, in classical antiquity, the vault of the sky was even called “the dance floor of the stars”.
