Milky Way Report
Home to Earth Our Earth is part of the galaxy known as the Milky Way. Astronomers for centuries have pointed their telescopes toward the Milky Way trying to discover the mysteries the galaxy holds.
The white light that one can see is known to be the origin of our solar system. Milky Way galaxy is a gravitational bound system consisting of stars, stellar remnants, an interstellar medium of gas and dust, and dark matter. It was named after the milk because of its appearance. It happen to look as a dim glowing arching across the night sky that can only be seen by the telescope. The Milky Way is a combination of different aspects that contributes to its incredibility. These include the age, surrounding galaxies, and clusters.

The Milky Way was first determined by Galileo Galilei with his telescope in 1610. Thanks to Galileo because before the use of his telescope, the formation of stars was a confusion to most astronomers. With the use of a telescope, Galileo studied the Milky Way and discovered that it was composed of a huge number of faint stars. There was a confusion on stars. Until 1920, astronomers thought that all stars were contained inside of the Milky Way. After Galileo’s telescope, other astronomers became more creative on understanding that the Milky Way is just one of many galaxies now known to be billions. The Milky Way contains more than one planet like the solar system which is located within the disk. The solar system is located on the constellation of “gas and dust called the Orion Arm” (Wikipedia contributors). We are located in the Orion arm of the Milky Way
Long before Life reached Earth, the Stars were discussing among themselves. They all wanted their own space, and to remain close to each other. Many wanted to watch Life grow in it's more primitive, small form. Many stars went far away to to other galaxies, both cold and lonely and soon-to-be full of life. But this story happens on our own galaxy, the Milky Way, were 6 stars were disputing between themselves who'd be the Pole stars. And so it went, that the stars fought and
This paper will introduce you to the incredible topic which is black holes. A black hole is a region of space time exhibiting such strong gravitational effects that nothing can escape from inside it. (NASA) No human has ever entered a black hole and there is still a large mystery about them; we have very little idea of where the matter that enters them goes. A black hole cannot be looked into either, as it sucks all the light into the middle of it. Space programs use special satellites with certain features that allow them to see these black holes. A black hole can be big or small, sometimes forming when a star is dying. Some scientists speculate that there can be black holes just 1 centimeter large. There are multiple types of
In our Milky Way galaxy, there are over a hundred billion stars, and within the universe there are billions of galaxies (Classifying Stars). Astronomers have always come up with different techniques to make their jobs easier. One important technique in, not only astronomy but science itself, is trying to classify something into groups to find a certain pattern. Since there are so many stars in a single galaxy, astronomers must find methods for organization. Stars are not all the same, they vary in size, temperature, and brightness. To keep track of all these different characteristics, astronomers had to come up with a diagram. The Hertzsprung-Russell diagram is one of the most useful plots for stellar astronomy (Classifying Stars). The diagram
Stars start off as clouds of gas that are usually in the spinning “arms” of a galaxy
a. The Milky Way galaxy is where our solar system is located in the universe.
2. The Milky Way galaxy is the constellation that earth belongs to, the sun is just another star within it.
There are billions upon billions of stars in our galaxy but only about 2000 of those are visible to us at night. Although there is one star that we are able to see during the day, but only because it is the closest one to earth, this star is the sun. Because the brightness of the sun is so vast we cannot see other stars, but when the sun sets we can see an abundance of celestial objects. The sun appears to be what some would call “the largest star” but it is only an average sized star, there are a countless more that are hundreds times the size of our sun. When we look up into the night sky and focus our eyes on what appears to be a star we often notice it twinkling, this is caused by turbulence in earth’s atmosphere. The atmosphere is like a lens and makes a boiling effect causing stars to look like they’re twinkling. Astronomers have discovered clusters of stars forming patterns, we call them constellations and there are roughly eighty-eight in our night sky. Stars can come in all kinds of different shapes sizes and distances, which causes some stars to appear closer than others. Bigger stars tend to shine more brightly than smaller stars. Even though a star seems bigger and brighter than the others doesn’t actually mean it is, it could just be a star closer to earth than most. The closest star to us is Alpha Centauri and is approximately four light years from earth meaning it takes four years for the light from Alpha Centauri to reach
The Earth is located in the Milky Way, which is a part of the Virgo Galaxy Cluster. The Virgo Galaxy Cluster is in turn apart of the Virgo Supercluster which is just a small amount of the visible universe. At the time of publication, Plait mentions that visible universe is “90 billion light years and expands every day…due to dark energy.” (Plait) He also mentions the idea that the universe could be part of a “larger multiverse that extends forever both in time and space.” (Plait) Even more incredibly is the thought that “we can only directly see 4% of the universe.” (Plait)
Many physical properties of stars can be found by using a little bit of light. One property of a star is luminosity. Luminosity is the quantity of energy created in a star and then released as electromagnetic radiation. The brightness of a star is a blend of luminosity and distance of a star and can also depend on the quantity of energy absorbed in the direction of a star. Another property of a star is distance. Astronomers use parallax to establish the distance to an object. As Earth travels around the Sun, they monitor neighboring stars from various positions. They are then able to measure how much the star seems to move to establish the distance to the star.
Tired of games always taking place on the same planet? Do you want to go out into space and unleash your inner space pirate? Or are you just looking for games where you can explore the galaxy? Then take a look at this list, you are sure to find something that you’ll love playing.
Milky way Midnight is a better candy bar than others, in taste and quality. Milky Way Midnight tastes very good and is rich and creamy.
Texture: It feels like a wash sponge,but a little more softer and kind of gooey.
It is considered a near-twin to the Milky Way galaxy.Since the gas in Andromeda's halo is dark, the team looked at bright background objects through the gas and observed how the light changed. This is a bit like looking at a glowing light at the bottom of a pool at night. The ideal background "lights" for such a study are quasars, which are very distant bright cores of active galaxies powered by black holes. The team used 18 quasars residing far behind Andromeda to probe how material is distributed well beyond the visible disk of the galaxy. Their findings were published in the May 10,

The Milky Way received its name from the milky, white band of stars that go across the celestial sphere visible from Earth. However, in Greek mythology, it is said that Zeus placed his mortal son, Heracles on Hera’s breast while she was asleep so the baby could breastfeed to become immortal. When she had awoken to a strange baby feeding off of her, she pushed Heracles away and a stream of milk sprayed through the night sky forming the Milky Way. It is estimated that about 200 to 400 billion stars are located within the galaxy. The Milky Way is also one of the larger galaxies that have a circumference of about 300 thousand light-years!
