 THE SATURN PLANET THE UNIVERSE THE SATURN PLANET In 1969 the first man landed on the moon to this day man space travel is it not ready yet to look Mars even another planet. With the passage of time, the science has been developed and made the impossible to possible. With the help of the science and modern instrument we can see outer space. Today our topic is Saturn, Lets quick view on Saturn and search for life another planet.                             SATURN PLANT AND ITS RINGS Saturn is not only sixth planet of the solar system but also the largest planet after Jupiter. With the approximate  distance 1.4 million kilometres to the sun the planet takes 29 years and 166 days to complete the one orbit. the minimum distance between the Earth and Saturn is 1.2 millions kilometre. The diameter of Saturn is 120500 kilometre. The weight of the Saturn is 95 of earth masses. Which means Saturn mass is 95 x bigger than Earth. Because of its size satin was covered thousands of years ago even b

THE SUN OUR SOLAR SYSTEM THE UNIVERSE    The sun is main source of energy, it is necessary for life on the Earth, without it, there is no life on the Earth. It is the main part of our solar system. With its great gravitational force, all eight plants, including Earth are orbiting the Sun. The sun is huge ball of hot, glowing gases. It is only star in our solar system. The hottest part of the sun is centre or core.                                             THE SUN While billion of stars are scattered true hot the universe the one of the centre of our solar system. Plays a special role for us here on earth. I was informed about 4.5 billion years ago in the milky way galaxy. It was born when a cloud of dust and gas known as solar nebula collapsed and it's the middle of these formation matter condensed into a burning ball of gas become our sun.  The sun's fiery nature along with great gravitational pull and an extensive magnetic field helped it to become the heart of our solar sy

 THE MERCURY PLANET THE UNIVERSE Now when you think about the physical characteristics of Mercury, I am sure you imagine it Being the closest planet to the sun but also that it is gate Rock floating in space.  THE MERCURY PLANET IMAGE You would not be to for wrong with that but it is much more interesting than what you may first think. The first thing that notice is that it actually does have a colour. It is not just different shade of grey colour.  Aur example, that Mercury consists of approximately 70% metallic and han 30% silicate material. So it's actually more metallic than Rocky.  MERCURY IS ORBITING THE SUN Because of this Mercury density is the second highest in the solar system at 5.4 2 7  grams per centimetre cube only slightly less than the planet with the greatest density that of earth at 5.5 15 grams per centimetre cube. If Mercury happened to be the same size as Earth, that would mean it would have pretty much the same gravitational pull as its surface.  but being the

 THE VENUS PLANET THE UNIVERSE  There is any place in the universe where the sun leaves the West every day. We have left our land behind and come forward. The sun is shining about 40 million km from the earth. But stay! A planet is orbiting between the Earth and the sun, which we called Venus.                                    Surface of the Venus Planet    Volcanoes keep bursting in the Earth of Venus as it is close to the sun. Water rains from heaven on our earth But the  acid rains on the Venus.    Venus, also known as the evening star and morning star, is actually the brightest star to see from earth. After all, why is Venus the brightest from earth?. The main reason for this is that this planet is much closer to Earth. And the other important reason is that there are clouds of gas around Venice for about 250 km when the sun light falls on Venice, it sends back 70% of the light, which is why it is the largest planet to shine in the sky.                           HERE IS SURFACE OF

 THE MOON PLANET THE UNIVERSE The land we live on actually smaller then you think. There are millions of human beings , states and countless religions on earth. But our Earth is a small particle against the whole universe. We take you on a journey to the universe and leave our earth and search for a new world where you will be amazed to see everything.                                           OUR EARTH  We start our journey with our nearest neighbour the moon. The moon which we actually see every night shining in the sky, is 384000 km far away from us. If we put all the planets in our solar system between the moon and earth, the distance between Earth and Moon may be covered. 30 Earth can be found in middle distance between the moon and the earth.  OUR MOON REALITY OF THE MOON PIC AND THE UNIVERSE  The main question is that which photo has found on the moon by science?  We were thought from childhood that there was a beautiful doll photo on the moon. But in 1969, when Neil Armstrong m
