The sun is at the center of our solar system. It was formed 4.6 billion years ago, together with the other large bodies of the solar system from a rotating, slowly compressing gas and dust disk. The sun is an average star in terms of size and luminosity, and its lifespan is expected to be several billion years.
The enormous amounts of energy that are produced in the sun by nuclear fusion and constantly emitted form the basis for almost all earthly life forms. To date, many physical phenomena observed on the Sun are still not fully understood - no other celestial body influences our daily lives as much as the Sun does. Just the description of the religious aspects of solar observation handed down through the millennia of human historiography fills volumes.
Today, we probably observe the sun more intensively than our ancestors: Solar space probes like SOHO send data to Earth around the clock, and even in modern times they can still trigger hectic measures. For example, when there are serious disturbances of electronic equipment on earth satellites and on the ground as a result of strong explosions on the sun.
This poster, created in collaboration with Prof. Schwenn of the Max Planck Institute for Solar System Research, summarizes the most important facts about our star.
