made laws of planetary motion and if he didn’t make those discoveries we wouldn’t be where we are today with our space explorations. His first law was the law of ellipses; the main law is that all planets revolve around the sun in an ellipse with the sun at one of the two foci points. Explains that planets are orbiting the sun in a path described as an ellipse. An ellipse can easily be constructed using a pencil‚ two tacks‚ a string‚ a sheet of paper and a piece of cardboard.

Precambrian Period – The beginning of life Our planet formed from a cloud of dust and gas some 4.56 billion years ago. The Earth’s vast history is divided in four major eras: the Precambrian‚ the Paleozoic‚ the Mesozoic and the Cenozoic. The Precambrian era covers most of our planet’s history and lasted from Earth’s inception until 542 million years ago. It was during this era that the Earth became solid‚ the atmosphere became breathable and life emerged. There is little evidence about the events

a crystal sphere that spun around the Earth. He thought that the planets traveled on spheres of their own. To account for the more subtle motions‚ Ptolemy believed that each planet also moved on a smaller sphere - an epicycle. ------------------------------------------------- Two commonly made observations supported the idea that Earth was the center of the Universe. The first observation was that the stars‚ the sun‚ and planets appear to revolve around Earth each day‚ making Earth the center

my body was there. I loved the way they represented what happened to Arthur on planet earth in a gross way where the house to be demolished for a pathway was the earth in the galactic space. I loved the idea of having a fancy galaxy with a president who has two heads and three arms. I can’t imagine what it will be to have an alien friend who reveals his identity only a couple hours before the destruction of the planet earth. The book sounded so absurd that it just made it funny‚ but I felt like

“Great‚ Mercury is about to retrograde again.”? Me either. But it is a subject that has gained my full attention recently. I am by no means an astrology buff‚ but I know that Mercury is one of the planets that receive the most attention‚ at least from the little that I have read. While the different planets‚ stars‚ and space in general has never been one of my top priorities‚ I do love research and decided to look into exactly what Mercury retrograde is and if it plays any significant role in life

As this shows a progression in their thoughts from the earth to the solar system and then end up talking about the universe; as they start to get more vivid and imaginative about how they life on other planets are and their this shows how their imagination is getting more bigger and more vivid.

Mars Rover Curiosity Mars is a planet that has made individuals question the possibility of many aspects‚ whether that would be extraterrestrial or questioning if life is habitable outside Earth-like conditions. John Grotzinger mentions in his academic journal‚ “all science begins in Star Trek Mode: go where no one has gone before and discover new things without knowing in advanced what they may be.” Something that sparked the beginning stages of study about the planet how similar Earth and Mars is

Even some fiction movies make us think that one day we can go to live on another planet. However‚ for the following reasons I do not support the idea that government should spend as much money as possible on developing space technology for the exploration of the moon and others planets. Space technology is very expensive and needs a colossal investment. Meanwhile we need much
