The Sun

                        

We know that the sun sustains life on earth, we also know that we are here by chance and the Earths population hangs on the balance of extinction from its mighty force. Earth is just the right distance from the sun for inhabitants to sustain life, are we the only ones in the universe my guess is no. It would be ignorant to believe that Earth is the only planet in the entire expanding universe that could sustain life.

The Sun is a huge ball of burning gas that has a diameter of 870,000 miles and its core burns at an amazing 27 million degrees Fahrenheit. Its awesome power controls the gravity of Earth and all of the other planets that orbit it. If you think about it Mars is our neighbouring planet and it is only 56,000,000 km to Maximum 399,000,000 km away from earth depending on its orbit cycle.           

                  

Mars is too cold to sustain life or an atmosphere like Earth. Some think that Mars use to sustain life but that goes against the rule of the sun. As the sun gets older it will expand before it explodes, and as it expands it will burn up all of its neighbouring planets stripping the atmosphere off our planet and killing everything in its path. This wont happen in our life time or many generations to come so there is no need to panic unless you have plans to stay alive for the next 5 billion years.

There are other dangers from the sun like solar flares, these are storms that happen on the suns surface like an eruption from a volcano on Earth. On the Suns surface though these are much more powerful, a small storm could reach the Earths surface disrupting televisions, satellites and pretty much everything electrical on our planet. A single flare could travel billions of miles through our galaxy within a matter of hours.

                   

Up until recently we only ever could see one side of the sun that was the facing the Earths surface. The sun rotates one revolution every 27 days making it very difficult for scientists to study its surface from Earth which rotates once every day, satellites orbit the earth once a day also making it almost impossible to study any point of the sun at any given time.

These new images that we get in 2011 from two different satellites on two different angles of the Suns circumference lets scientists study the surface of the Sun with ease. Two satellites were launched in 2006 with the best of imaging technology and communications Earth had to offer, they reached their destination in 2010 and some tests were done to make sure that everything was up and running and working properly.       

                   

The two satellites are positioned exactly 180 degrees apart catching both sides of the Sun at the same time, so as the Earth turns away from the Sun scientists can be assured that they will catch live feed from the suns surface. The information is endless that these scientists are getting from these two satellites, they will be able to monitor the weather patterns on the surface and they could even determine the age of the sun.

Now instead of getting 2d images that are relatively useless to the new technology we can view the Sun in stunning HD3D live feed. This new technology is ice breaking and it opens a new window into a galaxy we really know very little about. With every star there must be orbiting planets, our second nearest star Proxima Centauri which is 4.37 light years from our sun and almost impossiabe to reach in our life time. Saying that we didn’t think for one second that we could even accomplish this much 10 years ago.
