We are living on earth, the earth is our one and only one home for us.Now far from the earth we are going to finding deep in the cosmos. On our neighbourhood Moon, there is no any kind of sky, not any kind of sea over there and not a living things.There are only marks of cosmic stir.
Our star,Sun gives us light, air and all the things which we have. Our solar system revolving around the sun. And it is starting from planet Mercury. After that, planet Venus which is covered by clouds. It became a hell due to green gases. Mars, which is as bigger as the Earth .Between the orbit of Mars and Jupiter stone like asteroid are revolving around the sun. Jupiter having four big moons and dozens of small moons,which is solar system itself. If we gathering all the planets from the solar system and comparing with jupiter still it is bigger in mass.
There is very big red spot on the Jupiter which is nothing but the storm which are moving from lots of centry. And in size, it is bigger than 3 time of our earth.
In our solar system, Saturn is the very beutiful planet in out solar system. Around the saturn there are countless bolls which are made up of ice are revolving around saturn with shape of ring. Each of ice boll is like a small moon.
Uranus and Neptune are the outer planet of solar system. We didn't know this before,They were discovered only after the telescope was invented. Infront of this outer planet there are millions of icy bodies and the Pluto is one of them.
All the spacecraft till we send so far,from them Voyoger 1 is the one that travel farthest from home. In this we send some messages, this messages will be tell about us after millions of year. Like who were we, what did we do and what kind of music did you make.
This cosmos is like big ocean, and as we go further, such number of worlds will be found. We know that our sun is like other star, still it hold the icy bodies together with help of its gravity. About 5 billions ago, solar system was formed. This remaining pieces are present in the space it is called as Oort cloud. Nobody had seen them before and how to see them. These small pieces are as far away as the distance between earth and saturn. This cloud of comets surrounds the solar system. This is the second line of our address in cosmos.
There are planets for other stars too, we have come to know about these for a few decades.But now we have come to know that there are more planets than the stars. From this lots of planets are different from earth and there is no life. But what we know about life,till we know the life of only one planet that is earth.
Human eyes see very little part of universe, but science can aslo show what our eyes can't show.Infrared is light which is only seen by night goggles. If we see the space using that goggles then we see this Rogue planet, the world without sun. It is also called as Interstellar planet.
The middle of the rogue planet is molten and the surface is ice. May be there is a sea of water between these two, who knows what kind of parasite are swim in that water.
Now going to forward, In the below picture where are we exactly. Our earth is 30 thousand light year far from center of galaxy. This galaxy is called Milkywasy Galaxy. This is third line of our address in cosmos. Now you think that what is light year, which mean let there are 2 places which are from 1 light year distant each other, means light take 1 year to reach from that one place to another while the speed of light is higher than anything.The light-year is a unit of length used to express astronomical distances and measures about 9.46 trillion kilometres (9.46 x 1012 km) or 5.88 trillion miles (5.88 x 1012 mi).
Andromeda galaxy which is our neighborhood galaxy, this two galaxy and around all the small galaxies are called as Local Group. This is the fourth line of our address in cosmos.
And far from we can not see our galaxy too it is called as Virgo Supercluster. It is one of the thousands of cluster. As we see that each and every dot in Supercluster is Galaxy and in each galaxy how many suns and worlds are there that we don't know.
Despite this, this super cluster is a small part of the whole universe. Going to forward we will see that This is the universe whose strength is not known, in which numerous galaxies are included. This is the last line of our address in cosmos for the moment. This is Observable Universe.
Observable Universe means Universe which to visible,what is it exactly? We can not see beyond the limits set in the space.This is his own limit in the universe. The universe outside this,is far from our range. It is not possible to reach the light toward us.Those of us think that all these stars,galaxy and clusters that are part of our Observable Universe are actually drop of the ocean like other Universe.Which can be called SUPER UNIVERSE. Universe of Universe who has no limit.
