Introduction

Take a look at the sky above. You see the Sun, the Moon, and the Stars. You see clouds, specks of dust, and water vapor. But you can't see x-rays, gamma rays, and infra-red rays. D' you?
What you're seeing is just a tiny part of the giant Milky Way Galaxy. It's common to see these moveable objects day or night. But out there in outer space beyond the naked eye are other celestial bodies. This is a result of the atmospheric scattering of bags of dust, molecules, light, gas, water vapor, and other unidentified materials.
These scatterings are probably due to various energy wave-lengths, specifically, Mie, Rayleigh, and non-selective scattering.
Nevertheless, at certain seasons on a very clear moonless night, "the broad-band of faint light", or the Milky Way Galaxy, or the Galaxy can be seen.
The Milky Way Galaxy contains the Sun, the Earth, the Moon, stars, clusters of stars, and all the planets in the solar system plus trillion of stars(about 200, 000, 000, 000,000) stars, huge clouds of dust, and gas.
The largeness of the system is so vast that "10 smaller galaxies orbit it as a satellite revolves around a planet."

The Milky Way Galaxy

In this article, I will be showing you how you will be using the Sun, Moon, and stars as a directional vehicle to find your way out of the woods, or on the sea, if ever you get astray or lost. In addition, I'll show you how complex and complicated the Milky Way is.
The galaxy is reported to be dated 25 billion years old and not beyond. But the pre-galactical age is 30 billion years. This means that the Universe had existed for over 5 billion years before the Big Bang took place.
These ages are only assumptions. For no one know when the galaxy was formed. Also what forms the Universe was before the Big Bang took place, that cosmologists, scientists, and all of us will never know. It even pre-dates the existence of the first primordial beings in the Universe.
The Galaxy rotates clock-wise at the North around an imaginary axis, called the Galactical Pole, or around a point further from the central line of the system.
All other spiral stars and clusters of stars, including the Sun, which some persons thought to be stationary at the center of the Solar System follow in the same clockwise direction. They revolved at the center of the galaxy. It'll take the Sun 200 million years to make a single revolution at an astonishing speed of 155 miles per second!

Watching the Night Sky

Seeing the Milky Way Galaxy

What we saw with the unaided eye during the day or night is just a tiny fraction of the huge and gigantic Milky Way. Astronomers are foremost in studying and understanding the Galaxy. Along with the scientists and astronauts, and using big powerful, reflective telescopes, have taken a good look at the galaxy for us.
Actually, most of the stars we see in the night, except the Sun, that we see in the daytime. But it's common to see the Sun 24/7 in certain parts of the globe at certain seasons of the year!
Rare are the times we saw Proxima Centura at the early hours of the day before the Sunrise on the horizon though the sky is visible by the rays of the Sun. If the Sun does not rise by 6.06 AM, Proxima will still be visible. Proxima is the star that is nearest to the earth.

Population One Stars and Others

In the day, clouds and dust, including the Sun's rays or sunlight hide most of the stars from our views. Stars are either young or old in their formative periods. Younger stars like the Sun are very luminous in their formative periods. But not all older stars can be seen in the nighttime. The point is that the younger the stars, the most luminous and brightest these are for the naked eye to see them at night.
The Sun which is a Population1 star seems to be the most youngest in the Milky Way Galaxy. So it's very luminous for us to see it in the day, then the Population 2 stars, which are 200 trillion miles away from the Sun!
Our vision of the stars in the daylight is obscured by the solar sun. So we cannot see them. The Sun is here taken to be 93, 000,000 miles from the earth. But the very massive Population 2 stars with a light-year of more than 100, 000 light-years are more than 200 trillion miles away from the earth!
A light-year is the distance light travel within a vacuum in one year. This is 5.88 trillion miles.
Young stars like the Sun are active, violent, blazing, and volcanic-like. Other young stars with this nature at night are blue and red.

Milky Way Galaxy View

The Sagittarius Galaxy

The Sagittarius view is the best way to observe the Milky Way. Here it appears broadest and brightest with vanishing luminosity at the stream called Scutum Scorpio.
The reason is that the constellation Saggiturius is near the central bulge of the galaxy. The great star clouds that can be seen with the naked eye are all in Sagittarius and are not hidden by bags of dust. These clouds and specks of dust even prevent astronomers from using visible lights to see the bulging center. So, Astronomers and other galaxy scientists use radio waves, infra-red lights, and x-rays to probe into the clouds.
The use of these radiation tools has detected very unique objects in the central region of the galaxy.

The Big Bang

The galaxy did not evolve on its own. It did not come into being by an evolutionary process. They're a cause. The science of physics was not there back then. We're indebted to the Jews for providing the answer in their Holy Books. The words "Let there be light, and God saw the light that it was good".
Before the light was made to appear, there was already light. But it was wrapped up in thick darkness, a corrupted state needing a re-creation or a type of purification process, Genesis 1:1-4.
All that we know of the pre-galaxy years was that it was good, pure, and blissful. The post-galactical system contains clouds of dust, haze, gas, and other cloudy items preventing the eyes, powerful telescopes, and even radio waves from detecting certain objects, stars, and clusters of stars in the sky.

The Milky Way is a Cluster of Stars.

Stars, clusters of stars, or associations are the major component of the galaxy. They exist as single stars like the Sun, or as double stars, plus groups of stars containing ten to thousand members.
They provide a certain direction to travelers or seafarers. Astronomers have advised sailors to always travel south when leaving port by sighting the North Star or Polaris.
Persons losing their way in the forest can utilize the direction of the stars to greater advantage, and maneuver their way out of the woods. Mariners likewise where they compass failed or develop a technical problem.

Persons falling out of air-wreck can likewise took advantage of the directional principle to find their way out logically.

Division

The Milky Way is a complicated system. The structures are divided into:

1. Globular clusters. These are the largest and the most massive clusters of stars because they have a rough spherical appearance or surfaces. More than 130 globular clusters are identified in the galaxy.
2. There are very luminous, and 25,000 sun's luminosity(like the solar sun) is the equivalent of one globular cluster!
3. The Sun's luminosity is 3.83 x 1026 watts. Now, if a star was four times the luminosity or radiation power of the Sun, it is 4 x 3.83 x1026.
4. Each cluster can be 50 times brighter than the Sun. The best known is the Omega Centaur. It's the most imposing Globular, containing the oldest stars, and has a maximum life-year of 16 billion years.
5. Open clusters. These are smaller and less massive. They are younger stars.
6. Stellar associations. They are much younger stars that are luminous as open clusters. They are very luminous and some are brighter than the brightest open clusters or globular stars. Their luminosity can be 1,000,000 times the luminosity of the Sun. You do the math and see.
7. Moving groups. These are remote stars or remote object organizations. These moving groups help Astronomers make correct galactical measurements. Hydes moving group is the best known.
These clusters of stars are still being studied for birthing new stars, objects, and satellites.

The Milky Way Galaxy Cluster

⦁ The Sun is not the center of the Milky Way Galaxy. But it's the core of the solar system. It is a "dwarf star" among the other stars in the Milky Way. Flames of 25,00 to 500,000 thousand miles shoot out from its surface.
⦁ The Galaxy as a star system may contain up to one-hundred billion or 100,000,000,000 stars plus intercellular dust, gas, cloud, other matters. They form a unity, different, formation and circular motion.

⦁ The Milky Way is one galaxy among others. The Andromeda galaxy or M 31, its companion group M 32 and NGC 205, and other so-called Magellan clouds are external galaxies.
⦁ The Galaxy can be seen from anywhere especially, the Andromeda and Magellan clouds at night with the naked eye from the Southern Hemisphere in the world.
⦁ "The Southern part is much richer in stars than the parts visible from the Northern Hemisphere"-Camille Flammarion.
⦁ Hence, it's much easier to view the Galaxy from the Southern Hemisphere starting from the Sagittarius stream upwards.
⦁ Galaxies are more numerous than stars. But any unit of a galaxy is a star system.

The Radiating Rising Sun

The Sun is central to the solar system. It's not the center of the  Galaxy.

Finding Way Out of the Woods by the Sun

I was able to take advantage of these as a boy when I nearly lost my way in a strange village that populate less than 20 people. It was noon-time and it happen I visit a technical school friend while I was a grammar school student.
In those days, tracking is the only mode of transporting humans and goods in the village. It was Sunday, and I took leave at 3.00 PM. I arrived safely to see my friend.

At 5.00 P.M. I think it's time for me to leave. Halfway, I lost my direction. Realizing that the Sun(a star) was ahead of me during the journey, it has begun to set.
I realized that if I began to follow the setting sun, I can make my way out of the village. That I did and it took me to the precinct of a public hospital, on a major road that accommodate my school and the surrounding community. Thank goodness, I got back to school. So, always observe the Pole Star or the Solar Sun when traveling, and when you get lost, use it for your good.
