SOLAR SYSTEM

Solar system is a place where the Earth, our living place is located. Solar System consisted of a lot of space things that round over the Sun as the center of Solar System. These space things are variates. For example planets, asteroids, comets even meteors. These space things Have their own orbit. orbit is a kind of path that passed by the space things.



Planets are space thing that orbited around the sun that have almost circular orbit. Things that make the other space thing and planet differ are the shape of their orbit. Beside that unlike stars like sun, the planets don't have it's own light (can't produce light). The planets only able to reflect the light from the star that come toward them. There're more than 9 planets that orbit the sun, and will be more as the development of research.


Planets are divided into two. Inner planets and outer planets. These two kind of planets are separated by the Earth as their separator. That's also means the inner planets consist of Mercury and Venus. And the outer planet automatically consist of Mars until the outer planets.


The different of these kind of planets are based on the matters that consist the planet, and the planet's size. The inner planets mostly consist of metal and have small radius. That's why these kind of planets are dense. Whereas, the outer planet are mostly consisted of gas and less dense than the inner planets. but, their radius are large.


Between Earth and Mars, there're a lot of asteroids that orbit the sun. These orbited asteroids form an asteroid belt that orbit around the Sun. Sometimes, some asteroids are out of it's orbit and being pulled by planets gravitation. This asteroids then called meteor now (actually not all meteors are come from asteroids).


the most well known space thing is comets. Comets are also space things that orbit the sun. They have very elliptical orbit. The most well known comet is Halley Comet. This comet can be seen every 76 years. this is because this comet has an elliptical orbit.

People has study the solar system and the universe since centuries ago. The studies have bring out two theories about the solar system. The first theory is Geocentric theory. This theory is the oldest theory of Solar System. This theory said that Earth is the center of Solar System. The sun and the others planets are
orbit around the Earth. This theory was based on that time observation that show the moves of the sun which known as the apparent motion of the sun and the others planet revolution.

The second theory is Heliocentric Theory. This theory said that the sun is the center of solar system. Earth and the others planets are orbit around the sun. This theory are recognized by a lot of people now due to the research that showed the facts that Sun is the center of Solar System.


There're still a lot of things that unknown by us. For example the increase of the planets due to the development at research and technologies. So, we must grow our curiosity for knowing more about this universe.

NASREDDIN'S COAT

One day Nasreddin had been invited to the dinner party. He went to the party by wearing old clothes.

When he arrived in the party, nobody looked at him and nobody gave him a seat. He got no food in the party so he went home and change his clothes

Next he put on his best clothes. He wore his newest coat and went to the party again. The host at once got up and came to meet him. The host offered him the best table and gave him a good seat and served him the best food

Nasreddin sat and put off his coat. He put his coat and said; “Eat the food, Coat!” the hosts and guests were very surprised and asked Nareddin; “What are doing?” Nasreddin replied calmly; “When I came here with my old clothes, nobody looked at me. Then I went home and put on my best clothes. I came back in my newest coat and you all give me this best food and drink. So, you give food to my coat instead of me”. Getting Nasreddin's answer, they just shook the head.

EARTH PROTECTORS AND THE MIRACLE OF QUR'AN

Earth protectors are a kind of protector above the Earth's surface. These protectors protect Earth from many dangerous things that come from outer space such as radiance, etc. These protectors prevent those dangerous things reach Earth's surface. So, they won't danger lives on Earth. Without these protector, Earth will be a dead planet like the others planet.

One of these protectors is Earth's Atmosphere. This Atmosphere are divided into seven layers that have it's own functions. Atmosphere layers main function is an ability to "return" almost all particles and radiance that come from the outer space or from Earth back. This ability can be analyzed in the water cycle.

Atmosphere layers are divided into seven layers. These layers are Troposphere, Stratosphere, Ozonosphere, Mesosphere, Thermosphere, Ionosphere, and Exosphere. These layers have different "Returning" ability in every layers. (www.harunyahya.com)

Troposphere is the nearest atmosphere layers to Earth's surface. Part of the water cycle is happens here. In this layer, water that come from evaporation from Earth Surface are accumulated and form cloud. Then, this cloud is condentsationed by the cold temperature in this layer and fall back to Earth as rain.

The second layers is Stratosphere. This layer has an ability to return ultraviolet radiance from our sun and the others star back to the outer space. This ability is almost same with Ozonosphere's ability. This is because there's a gas named ozone in these layers that can return the radiance back. This gas is formed by three oxygen atom that was "tied" each other. Uniquely, this layer not return all the radiance back to the outer space, but absorb a little of them. A little of this radiance are needed by plants on Earth to produce energy.

The fourth layers is Mesosphere. This layer's function aren't known well. But, this layer function is mainly to return the radio waves that come from earth surface. This ability has allow humans to broadcast radio and television channels worldwidely without any cable.

The fifth layers is Thermosphere. This atmosphere layer are located above mesosphere. higher than Thermosphere, there's Ionosphere, the sixth layers. Ionosphere is the atmosphere's layer that was formed by many ionizationed gases that was accumulated above Thermosphere. The last atmosphere layers is Exosphere. This atmosphere layer is the highest atmosphere layers among the others atmosphere layers. These layers main function is to return the radiance that come from outer space.

Beside Earth's atmosphere, there's another earth protector. This another protector is "Van Allen Belt". Van Allen Belt are formed by the Earth magnet. Together with Earth Atmosphere, Van Allen Belt protect Earth and Lives on it from the dangerous radiance that come from outer space.

These facts are newly invented in the 20th century. But, did you know? these facts are already told in Al-Qur'an 14 century ago. Allah had told us about it in Al-Qur'an.The Qur'an says, "[He] revealed, in every heaven, its own mandate," in Surah Fussilat 12. In other words, Allah is stating that He assigned each heaven its own duty. It is a great miracle that these facts, which may not be found without the advanced technology of 20th century, clearly stated by the Qur'an 1,400 years ago.
