A comet's journey through the solar system is dangerous and violent. From the solar cell material, you can tear a huge jet of its tail. After it reached Mars - at about 2.3 million miles away from the sun - solar radiation began to boil water, in addition to the first step in breaking the comet. And if it survives all this, strong radiation and pressure, because it flies near the surface of the sun can completely destroy it. The cartoonist created this short film in the green space of NASA's Goddard Space Flight Center, Maryland, to show how the sun can cook comets. Comet ISON is such a journey. It began its journey from the Oort cloud region of our solar system and is now heading for the sun. The comet will reach the closest sun on Thanksgiving Day - November 28, 2013 - The sun surface skimming is just over 730,000 miles. If it is observed around the sun in the northern hemisphere with the naked eye, from what we now know Ison predicts is a particularly bright and beautiful comet, the comet will be visible. Even if the comet does not go down, tracking its journey will help scientists understand what the comet is made of, how it reacts in different environments, which will explain the origin of the solar system. Seeing how the comet and its tail interact with the vast solar atmosphere in the sun can teach scientists about the sun itself.
