Eventually Population II and then Population I stars also begin to form from the material from previous rounds of star-making. Larger stars burn out quickly and explode in massive supernova events. Supernova is the explosion of a star and is the largest explosion that takes place in space. Billions of stars groups to form galaxies and gravitational attraction pulls galaxies towards each other to form groups, clusters and super clusters. After 8.5 - 9 billion years, our solar system is formed.
We know this is going to happen because they are both moving into each other at about 100-150 kilometers per second. We are about 2.54 million years away and it is known to collide in four billion years. Our galaxy will not survive, but gravity will push the sun towards a new orbit which will drag earth and the other planets with it. (ADD ON) 3. The Milky Way has a ton of stars The Milky Way has about at least 100 billion stars.
A subject of debate for years, centuries even, has been that of Creation versus Evolution. Which one outweighs the other? Which is most heavily supported by scientific evidence? Many have mulled over the idea of One omnipotent God miraculously creating the world we live in today, modeling it according to His perfect plan. Others stand firm in the belief of a phenomena of space and matter where earth was brought into existence by a spectacular “big bang,” causing entire planets, ecosystems, and life forms to materialize from nothing.
On July 20th, 1969, the Apollo 11 with astronaut Neil Armstrong and his crew, guided by thousands of NASA technicians, supposedly landed on the surface of the moon. It was certainly one of the most extraordinary events accomplished by mankind up to that date. Neil Armstrong’s first words upon stepping on the moon surface will always be remembered “ A small step for mankind, a giant leap for humanity”. Ever since then, this achievement has been a matter of discussion by several groups that either believed or disbelieved this. There are people who believe that the entire moon landing was “ The greatest government conspiracy of all time”.
Besides the reason behind why the Congress puts tremendous funding in NASA each year than other departments and services is because the significance of human space exploration as it is guaranteed turning into one of the major global discussions within the next few decades. In fact, the period of waiting the people to decide when to start saving our Earth has ended long
Why did Columbus travel west? Why did Alexander the Great head east? Because it is that charm, that sense of unknown, that outlook for adventure and expedition which compels humans to explore new frontiers. The ultimate identification of adventure is in living on another planet, millions of light years away from Earth; where one would look up in the night sky with the knowledge that one of those brightly shining stars is in reality the planet that you were born on. However, it is a sobering fact to realize that the unfortunate reason for the human race to abandon the mother Earth and move to another planet is due to the risks caused by our own mutilation of nature whether it is by global warming or famine or nuclear threats.
Although, now one reason Mars is uninhabitable by humans is because of its non existent source of water. Jupiter, the fifth planet from the Sun, is surrounded by more than 50 moons. Jupiter is also the largest planet in the entire Solar System. The iconic ‘Big Red Spot’ on Jupiter is actually a storm that has raged for hundreds of years. This spot, itself, is bigger than Earth.
When we think of the moon, we usually think of a white glowing circle that is visible at night, and when we walk at night, we’ve probably asked the question, “Why is the moon following me?” However, there is more to that than the assumptions we made as kids. The moon’s relationship with the earth and people who studied the moon is categorized under the moon’s history; in ancient times. Also, the ancient people made up myths about the moon to entertain and fascinate people. There are many theories behind the formation of the moon. One of the most popular theories is the Giant Impact theory.
(Main Idea): In the words of Stephen Hawking “Sooner or later disasters such as an asteroid collision or a nuclear war could wipe us all out. But once we spread out into space and establish independent colonies, our future should be safe.” We like it our not, the humans of the future will live in the space, and life outside earth might influence dramatically the way we look. (picture colony in mars) • Moving away from the sun, our eyes will need to adapt to ambient with less amount of light. They will considerably increase, giving us a quite exotic appearance (show picture). • The extended exposure to cosmic rays and space radiation might induce mutations never seen before.
Did you know that only happy people are allowed in space? It is because you cannot cry on space as your tears will never fall… Wait, there is more… Did you know that there is a huge reservoir of water that is floating and orbiting in space, and which is the equivalent to about 140 trillion times all the water in the earth’s oceans and seas? Did you know that in 1962, the United States blew up a Hydrogen Bomb in space that was close to hundred times stronger than the Atom Bomb they dropped in Hiroshima? Wonder what difference it made up there? If you did not know the above realities, then read on for more such amazing facts on space that will interest kids, as well as adults.
