The solar system is about the system of the sun and the eight largest planetsare rotating around the sun. The solar system is formed by the billion years ago.The Four outer planetcan be rotate around the sun. The four inner planets are the smaller that is the mercury, Venus, earth, and mars and the largest planet is the Jupiter or Saturn.
Theseplanets can rotate around the earth. These are the planet that can revolve around the sun. The only on planet is available where we can live and it is called the earth. The atmosphere of the earth is best and can suit our nature. We can survive only in the earth in other planet we cannotsurvive because the atmosphere of the other planet is not the perfect for the living. Some planet is the hot planet and some planet is the cold that where we cannot survive. The atmosphere of the earth is normal. In the solar system the sun and star is present. The eight planets can be rotate around the sun and the earth is the 3th planet from the sun

A look up at the sky at night uncovers an expansive broad strip of light. This captivating line of light is the focal point of our universe, as observed from one of its external arms. Understanding the structure of the Milky Way has always been a difficult challenge as the Universe is huge enough to study. The close planetary system sits on the external edges of one arm in a circle of material. Cosmic systems are rambling frameworks of residue, gas, dim issue, and anyplace from a million to a trillion stars that are held together by gravity. Almost all enormous systems are thought to likewise contain dark gaps of huge masses at their focuses. In our system, that is the Milky Way, the sun is only one of around a hundred to four hundred billion stars.
Many observations and debates had been done on the Milky Way. Everybody was eager to know the reality behind this mystery. The band of light was first resolved into separate stars by a renowned space scientist “Galileo”, with his telescope. Galileo's discoveries are very famous.Cosmologists imagined that every one of the stars, known to mankind, is contained in the Milky Way. This assumption was done at the start of the 1920s. There was a big debate between Harlow Shapley and Heber Curtis about the topic. Later on, observations were made by Edwin Hubble and he brought up a conclusion that the Milky Way is actually one of the galaxies.
Milky Way Galaxy
Galaxy contains a star and many planets revolving around it. This galaxy is known as Milky Way Galaxy. The more profound we investigate the universe, the more cosmic systems we see. One examination was done in 2016 that evaluated that the perceptible universe contains two trillion or 2,000,000 million galaxies. A portion of those far off frameworks resembles our own Milky Way world, while others are very distinct. Milky Way is probably the only galaxy where life exists. What bounds the gas, dust and the big group of stars in the galaxy, is the gravity. The Milky way system is an enormous banned winding spiral galaxy. There are stars of various shapes and sizes. We see stars at night and wonder they are near but in reality, they are very far and appear in our Milky Way. The name Milky Way was given to our galaxy since it shows up as a smooth band of light in the sky when you see it in an extremely dark area. Since there are many stars in the galaxy, so it is difficult to count their number from the position where we are. An estimate says that there are around a hundred billion stars.
A light-year is mostly used to express astronomical distances. Since our solar system is much far away from the galaxy, so we can somehow say that solar system lies about twenty-five thousand light-years away from our galaxy.Our world likely contains hundred to four hundred billion stars and is around one hundred thousand light-years over. That sounds enormous, and yet it is. The Andromeda galaxy, known to be our neighboring galaxy, is around two hundred and twenty thousand light-years wide. We live in the outskirts of the galaxy.Just like the Sun circumvents the focal point of the Milky Way, the Earth circumvents the Sun. So, it takes almost two hundred and fifty million years for our sun and the planetary group to go right around the focal point of the Milky Way.
What NASA says about Milky Way
The National Aeronautics and Space Administration (NASA) is the US government agency that is in charge of aviation research, air transportation, and the ordinary citizen space program. Where explorers chart the continents of the globe, out astronomers have engaged themselves in making up the map of the spiral structure of the Milky Way. Utilizing infrared pictures from NASA's Spitzer Space Telescope, researchers have found that the Milky Way's exquisite winding structure is overwhelmed by only two arms. Beforehand, our cosmic system was thought to have four noteworthy arms.
NASA’s James Webb Space Telescope is the most dominant as well as complex space telescope. It will investigate the universe utilizing infrared light, from planets and moons inside our close planetary system to the most antiquated and far off galaxies.When we talk about the tremendousness of the universe, it's easy to hurl out enormous numbers, however progressively hard to fold our brains over exactly how huge and far various divine bodies truly are.
At the focal point of the spiral, a great deal of vitality is generated along with clear flares, once in a while. In light of the massive gravity that would be required to clarify the development of stars and the energy discharged, the space experts infer that the focal point of the Milky Way is a dark hole having a mass of millions or billions of times than that of the sun.Different galaxies have different shapes. Some galaxies have circular shapes, and a couple of others have strange shapes just like toothpicks or rings.
Introduction to galaxies along with certain facts and information about them
A large area in which there are trillions of planets and stars, surrounded by and carrying different types of gases along with dust particles is mostly known to be a galaxy. We can only see a handful of stars in the sky but in reality they are in trillions within one galaxy and you cannot even imagine how big that is. Still you would find a numberof realities to be yet discovered within the galaxies on which NASA and other space people are doing their researches and travels.
Galaxies are not in the same shape but each and every one is different from another. According to the astronomers, the number of galaxies which are present in the space in about hundreds and so far, from earth, we have only found, reached and conquered even less than 20% of that area. A whole huge world within the world exists in this area of the mighty universe and it is possibly said that chances are that there can be found life. Many astronomers, student researchers and professors from the California University are trying their best so they are discover more about life from there galaxies.
It is expected as per the research that life may be found on a galaxy names as ‘Andromeda’. It is a risky project which requires heavy budgeting and funding too. However, the astronomers highly believe that they will find life there and it will be the greatest discovery of all the times since earth has formed.There, in space, the galaxies are huge and unexpectedly huge that life seems to be a very small thing in it.
Considering their movement and sizes, we do not know about their orbits but they are also found colliding with each other a lot.The universe can also said to be a threatening space as per the nature that the galaxies collide too. Another fun fact as per the latest discovery says that the galaxies collide with each other and they shapes change from how they were before. The most common shapes of transformed galaxies are these:
- Elliptical galaxy
- Spiral galaxy
Astronomers, best from the world, have classified the galaxies into three sub categories:
- Spiral Galaxy:
As the shape says, the galaxy must have collided before and now it is names as this spiral galaxy. The best kind of galaxy which has a great example is the milky way. The whole galaxy is full on twisted and turned stars along with the gases surrounding them. Our earth is also a part of this galaxy which is named as the milky way. Every kind of life explored till now is human, animal and plants life which is found at earth along with a variety of microbes too. The galaxy has its own solar system which comprises of 8 or 9 planets and stars collectively which roam around themselves and the sun to cover their orbits, some of them make a duration of the day, while some other orbit way shows the completion of a year too. There are also a number of different satellites which are man made and sent to the space to gather information for the humans on earth. A lot has been explored and yet still to be discovered in space.
- Elliptical Galaxy:
They, the stars, theyoccur in a large amount in the whole universe. Such galaxies have dim light so that they can not be seen, found and discovered so easily as others. As the names shows the concept of eclipse, that is why these galaxies with dark themes are called as the elliptical galaxy. The scientists have thus given them a strange name. they are mostly red in color, and a range of dust also surrounds it. Cygnus A, is one the most famous elliptical galaxies and research of the astronomers is going on.
- Irregular Galaxy:
These galaxies are present in a very small amount and can say that the total area covered by irregular galaxies is about 20% of the total universe galaxy area. These galaxies do not have any certain shape or size and that why they are named by the astronomers are the irregular galaxy. Their shape has constantly become irregular due to the constant collisioins with other stars and planets in the space. Because the more small they are, chances are more that they will collide a lot. With the best example named as ‘metallic clouds’, such galaxies are the most bright one ever.
- Milky Way Galaxy:
The most important galaxy which has us and the earth and the solar system in it is called the milky way. This is a galaxy with a smooth range of rotating stars and planets with fog type space dust all within it. There was this teacher, Mr. Mathew Stanley who started research with a bunch of his colleagues and students and started researching about the earth and its location. This whole study was being done in the University of the New York. The milky way has been totally discovered till now that you can study the most of it with a telescope. The planets and the stars in this galaxy are quite old, even more than 4 to 5 billion years old.
Andromeda Galaxy is the spiral galaxy that is the approximately 780 kilo parsecs from the earth. Thefirst person that can describe about the Andromeda galaxy is Abs al-rahman al-Sufi.

The universe is described as a collection of objects in the space. There are billions of different galaxies in the universe. Other than our Milky Way, only three such cosmic systems exist that can be seen without a telescope and show up as a fluffy fix in the sky.
Magellanic Clouds, Large and Small, are the nearest cosmic systems that we can see without a telescope. These satellite systems of the Milky Way can be seen from the southern side of the equator. Indeed, they are around one hundred and sixty thousand light-years from us. The Andromeda Galaxy is a bigger cosmic system that can be seen from the northern half of the globe with great visual perception and a dim sky. Though it is 2.5 million light-years from us, yet it is drawing nearer, and analysts foresee that in around four billion years, it will slam into the Milky Way. Different cosmic systems are significantly further from us and must be seen through telescopes only.
Most important galaxy, Milky Way
Cosmologists match those we find in other common winding systems to the measure of residue in the Milky Way and the overwhelming shades of the light we see.The majority of this signifies give us an image of the Milky Way, even though we can't get outside to see the entire thing.
Why do we think that the Milky Way is a spiral galaxy? There are a few hints which prove this assumption. The first hint originates from the brilliant band of stars that stretches over the sky. That band originates from seeing the circle of stars that structures the Milky Way from inside the circle and reveals to us that our cosmic system is essentially flat.A few unique telescopes have taken pictures of the circle of the Milky Way by taking a progression of pictures in various ways.
The convergence of stars in a band adds to the proof that the Milky Way is a winding galaxy and not an elliptical one. On the off chance that we lived in a curved universe, we would see the stars of our world spread out all around the sky, not in a solitary band.
Main Types of Galaxies
The littlest cosmic systems may contain just a couple of hundred thousand stars and be a few thousand light-years over, while the biggest universes have trillions of stars and perhaps, countless light-years over.Cosmic systems can be found without anyone else's input, in little gatherings, and enormous groups. It is extremely uncommon to discover stars in the space in the middle of cosmic systems.Galaxies, some of the time slam into one another, with intriguing outcomes. These crashes can trigger blasts of star-arrangement notwithstanding changing the states of the galaxies that impact. Be that as it may, when galaxy impacts happen, singular stars don't crash, because of the huge separations between them.
Elliptical, Spiral and Irregular galaxies have been the three main types of Galaxies. More than 66% of all noticed galaxies are spiral galaxies. Spiral Galaxies have three noticeable parts: a flimsy circle made out of stars, residue, and gas; a focal lump of more established stars and a round corona of the most seasoned stars and gigantic star bunches.
Elliptical galaxies are elliptical, as their name suggests. They are commonly round, however, can extend longer along one axis, to such an extent that some take up a stogie like appearance. The Elliptical galaxies can contain up to a trillion stars and length 2,000,000 light-years over. Elliptical systems may likewise be little, in which case they are called predominate elliptical galaxies.They contain tiny gas and residue. Hardly any new stars are known to shape in elliptical galaxies.
Galaxies that are not winding, lenticular or circular are called Irregular cosmic systems. Irregular galaxies often lack a definite shape because they are inside the gravitational impact of different galaxies close by. They are loaded with residue and gas. They are isolated into two groups, Irr I and IrrII. Irr II cosmic systems just appear to have a lot of residue that squares the vast majority of the light from the stars. This residue makes it practically difficult to see particular stars in the system.
Prior to the twentieth century, we didn't realize that cosmic systems, other than the Milky Way, existed. Earlier cosmologists had characterized them as "nebulae," since they looked like fluffy mists. However, during the 1920s, space expert, Edwin Hubble demonstrated that the Andromeda "cloud" was a system in its own right.
Lenticular cosmic systems, for example, the famous Sombrero Galaxy, sit among elliptical and spiral galaxies. They're designated "lenticular" because they look like lenses. Like winding galaxies, they have a dainty, pivoting plate of stars and a focal lump, yet they don't have winding arms. Like curved galaxies, they have little residue and appear to frame in thickly populated areas of space.
There are several galaxies that exist. Tadpole Galaxy, Black Eye Galaxy, Sombrero Galaxy, Whirlpool Galaxy, Cigar Galaxy, Cartwheel Galaxy, Sunflower Galaxy, Bode's Galaxy, Comet Galaxy, Cosmos Redshift 7 and Mayall's Object are some of the galaxies that have been discovered.
