 The Sun sits at the center of our solar system it is the single most important provider of life of on Earth. Without the Suns warmth and energy there would have never been life on Earth. Imagine if the Sun went away, all trees and plants would quickly die off and the more resilient life would only linger for a short time. It would take some time for the volcanic lava in the center of the Earth to cool off  and for the oceans to freeze but over time Earth would become a giant ice ball.

Although nearly all life we can see would simply cease to exist without the Sun, there are some forms of life that could survive. Microorganisms like chemoautotrophs that exist at the bottoms of our seas, and spores which have the ability to survive space travel could exist under the most extreme conditions. However it is unlikely that anything could thrive on a dry and barren planet without heat and water.

The Sun is about 4.5 billion years old which is roughly half of its lifespan and as time goes on the Sun will increase in temperature and brightness. The elements that the Sun is composed of are about 70% hydrogen 28% helium and a small 2% metals. 99.8% of the mass in our solar system is contained by the Sun and the rest by Jupiter.

Life on Earth as we know it is completely dependent upon the sun. Trees and plants rely on the Suns energy to give them nutrients. Humans need the organic life on Earth to provide oxygen and an atmosphere. Earth is in a delicate balance with the Sun and has been for a long time. Who knows if humanity will hang around long enough to see what the sun will become.

John Lennon was a member of a band called the Beatles which was one of the most popular musical groups ever. In my opinion John was the most talented of the four Beatles. He was responsible for writing most of the songs played by the Beatles.

Although the wave of the Beatles came and went before i was even born, their work will always be a huge part of our culture. While growing up I have listened to many of the Beatles songs and i have come to greatly appreciate them. Every now and again when i hear a Beatles song it will take me back to an earlier time in my life.

 When the Beatles were becoming famous they began to influence the world with their music. Some of the songs John Lennon wrote include "Imagine" and "In my life" which i feel show just how amazing of a mind John had. Although John was very much a peace activist, he could easily let his temper get the best of him. This could be seen in the song "How do you sleep" where John is tearing into Paul McCartney.

After the Beatles broke up John continued to create songs on his own such as "Jealous guy", "Mind games" and many others which i have also come to like very much. When i look at what John has created I think that he was of a higher caliber than most other people. It is so sad that someone of such influence and talent had to die by gunfire and yet this does not surprise me.

The person i will be writing about is Isaac Newton. Newton was a mathematician and physicist who lived in England from January 4, 1643 to March 31 1727. From what i know about Newton he was a very talented person who's accomplishments have been influencing scientists to this day. Some of Newtons most revered works focused on the laws of gravity, optics, and calculus. Newton put forth ideas that although were controversial served a huge role in the scientific revolution of the 1700's. Newton is well known for his law of gravitation

which is clearly complex and fascinating. Another thing Newton is know for is discovering that white light is composed of the colors red, orange, yellow, green, blue and violet. Newton also served in the development of calculus which people today are still trying to learn.

Newton had a very philosophical outlook on the universe which could be seen in his works. He was a big part of shaping the foundation of physics and arguably one of the greatest physicists to have ever lived, along with Albert Einstein.

After researching some of Newtons works i am motivated to know more about him and to understand more of what his works were saying. Newton's insights clearly have helped our understanding of the laws of the universe.

Recently NASA has announced evidence of water has been discovered on Mars. This discovery has made a great impact on the scientific community. If water were to be obtained from Mars it would revolutionize the way scientists view the possibility of life once existing on Mars and just maybe existing once again. However if water was found, the 1967 Outer Space Treaty would prohibit any attempt at getting close to the water due to the possibility of contamination.

A discovery that suggests life favorable water once existed on Mars is an outcrop of Iron-magnesium carbonates which are made when water comes into contact with magma. Another suggestive discovery are the many patterns on Mars's surface that are strongly believed to have been created by the flow of water. Finding water in liquid formation could be very difficult because of the temperature (average of -63°C) and pressure (0.6% that of Earths) on Mars. However there are still circumstances that could grant the possibility of liquid water existing under those conditions.



The possibility of Mars one day harboring life is very fascinating and it seems where there is water there is life. I am inclined to believe nothing is impossible and i will look forward to future discoveries with great excitement.
