Our Universe

What is Space? Space is space, empty space. It is full of energy and matter. You can’t even think what kind of stuff is in space. It’s an ocean of darkness and vacuum. It is not what you see in Star wars or Star trek, It is kind of different.

A WALK THROUGH THE UNIVERSE Space is big. You just won’t believe how vastly, hugely, big it is. I mean, you may think it’s a long way down the road to the chemist’s, but that's just peanuts to space. The observable Universe is 27 Billion light-years in diameter. 3

What is Universe? • Universe is everything that exists in the world. • It is something that made us. • Universe is the limit.

WHERE IT ALL STARTED It all stared with a explosion of a small bubble which was smaller than a pinhead known as the Big Bang. The explosion was so powerful that the stuff that came out of it is still moving forward making new galaxies and stars. Many people think that the Big Bang happened about 13 billions years ago but that’s not true, Big Bang happened more than 8 o Billion years ago and our solar System is pretty young. The picture in the bottom right is pretty Fascinating. Here you can see the early stages of the forming of the very first stars of our universe. The space telescope, Planck, has been observing the oldest light in the world, from just after the beginning of the Universe! These observations have now been collected into this map, showing the shape of the Universe when it was very young. The blue and red splotches you can see are the ancient ‘seeds’ of today’s stars and galaxies. !

How are we connected to universe Every one in this world came from universe. If we put it in more sciencetefic way it means that the stardust from space which consisted of carbon made us and everything in this world is about of carbon but that’s not it. But if you think it in a common way then there is a big reason that the universe is a sea of energy, deep energy and a tiny bit of that energy is given to us too, to our earth and its all cause that energy, we survive.

Universe and Time is pretty interesting, cool and sad. In order to explore space you need time. Let me explain it to you - When you see stars at night you think that is the most recent picture of that star but that’s not true, the stars we look at today looked like that about 3 to 10 billion years a ago, so this star looked like this when our solar system was being made with explosions and reaction and when think about it is pretty cool and seems astonishing. Scientist used this information to know what is the current size of the universe but they are never right, no one can because universe is full of mysteries and we don’t know of. What is sad about time is that it never stops (what we know of) and that’s why things change, people get old and die and the universe continues to grow and this is called the arrow of time.

WHAT IS A QUASARS? Quasars is a very energetic and distant active galactic nucleus. Quasars is the brightest light in the Universe.

HUMANS IN SPACE Yuri Gagarin, Neil Armstrong, John Glenn, Buzz Aldrin, Michael Collins, Alan P. Shepard and many more. All these great guys changed the way people thought about space and created a ignition in everyone’s heart to disclose the outer space, to know what the reality is just cause of one habit of humans-Curiosity.

HUMAN CURIOSITY Every human is the same in one thing for sure, “CURIOSIY” Our nature of finding the answer to anything, to ask the solution of the word “why” got us where we are now. Isaac Newton asked why does the apple falls from a tree, Albert Einstein asked why light travels in a straight path, Werner von Braun asked why can’t we go in space is what made the difference and the mysterious universe was introduced to us.

FOR THE FIRST TIME April 12 1961, Yuri Gagarin became the first person to go to space. May 5 1961, Alan Shepard became the first American to got to space. February 20 1962, John Glenn became the first American to orbit space. June 20 1069, Neil Armstrong became the first person to walk on moon. All these great men were the first ones and the best ones.

The Solar System • 8. 5 planets, thousands and thousands of planetoids and asteroids, billions of comets and meteoroids • Mostly distributed in a disk about the Sun • Sun blows a constant wind of charged gas into interplanetary space, called the Solar Wind

The Milky Way Galaxy is a giant disk of stars 160, 000 light-years across and 1, 000 light-years thick. The Sun is located at the edge of a spiral arm, 30, 000 light-years from the center It takes 250 Million years for the Sun to complete one orbit You Are Here There are over 100 Billion stars in the Milky Way The Spiral arms are only 5% more dense than average, and are the locations of new star formation

Time line of Space Exploration 1957 October 4 - The Soviet Union launched the first satellite, Sputnik, into space. November 3 - The Soviet spacecraft Sputnik 2 was launched with a dog named Laika on board. Laika did not survive the voyage. 1961 April 12 - Russian cosmonaut Yuri Gagarin became the first human in space. May 5 - Astronaut Alan Shepard became the first American in space. 1962 February 20 - Astronaut John Glenn became the first American in orbit. June 16 - Valentina Nikolayeva Tereshkova became the first woman in space. 1965 March 18 - While attatched to his spacecraft, cosmonaut Alexi Leonov became the first man to walk in space. June 3 - Astronaut Ed White became the first American to walk in space. 1966 February 3 - The Russian spacecraft Luna 9 became the first spacecraft to land on the moon. June 2 - Surveyor 1 became the first American spacecraft to land on the moon. 1968 September 15 - The Soviet spacecraft Zond 5 was launched and later became the first spacecraft to orbit the moon and return to Earth. December 21 - Apollo 8 was launched, and later her crewmembers became the first men to orbit the moon. 1969 July 20 - Neil Armstrong and Buzz Aldrin became the first men on the moon. 1971 July 30 - The moon rover was driven on the moon for the first time. 1975 July 17 - The American Apollo 18 and Soviet Soyuz 19 dock in the Apollo-Soyuz Test Project. 1990 August 24 - The Space Shuttle Discovery deployed the Hubble Space Telescope. 2001 April 28 - American Dennis Tito became the first tourist in space after paying the Russian space program $20, 000. 2006 January 15 - NASA spacecraft Stardust returned safely to Earth in a desert near Salt Lake City with the first dust ever collected from a comet. 2009 March 6 - The NASA spacecraft Kepler was launched. Its mission is to search for planets outside our solar system, in a distant area of the Milky Way.

Current Space Missions Currently Expedition 34 and 35 onboard the ISS. Their commander is Chris Hadfield who is an Canadian astronaut. Nasa has recently founded the first dark matter ever found with the help of AMS a 3. 7 billion dollars arm recently attached to the ISS.
