The Sun - challenge for scientists
Institut für Weltraumforschung, Österreichische Akademie der Wissenschaften
The Sun is our nearest star. It plays an important role in many processes widely ranging in space and time scales, from the global evolution of the whole solar planetary system and environments of particular planets, to the short-time elementary processes on the micro-level of separate particles and the electromagnetic fields. The Sun sustains the life on Earth and impacts our technological civilization. It may be considered also as a unique plasma physics laboratory of an astrophysical scale. High energy and large-scale processes realized there can not be easily reproduced in usual labs. Investigations of the Sun and solar heliosphere are of great importance for the study of behaviour of stars and space plasma in general. Unsolved problems of the solar physics stimulate progress in the fundamental science, as well as in the technological and engineering branches.
The main two aspects of the solar science which represent the focus area for the modern and future research effort are the following.
