In September 1984 a Summer School on Solar System Plasmas was held at Imperial College with the support of the Science and Engineering Research Council. An excellent group of lecturers was assembled to give a series of basic talks on the various aspects of the subject, aimed at Ph. D. students or researchers from related areas wanting to learn about the plasma physics of the solar system. The students were so appreciative of the lectures that it was decided to write them up as the present book. Traditionally, different areas of solar system science, such as solar and magnetospheric physics, have been studied by separate communities with little contact. However, it has become clear that many common themes cut right across these distinct topics, such as magnetohydrodynamic instabilities and waves, magnetic reconnect ion , convection, dynamo activity and particle acceleration. The plasma parameters may well be quite different in the Sun's atmosphere, a cometary tailor Jupiter's magnetosphere, but many of the basic processes are similar and it is by studying them in different environments that we come to understand them more deeply. Furthermore, direct in situ measurements of plasma properties at one point in the solar wind or the magnetosphere complement the more global view by remote sensing of a similar phenomenon at the Sun.

This book addresses and reviews many of the still little understood questions related to the processes underlying planetary magnetic fields and their interaction with the solar wind. With focus on research carried out within the German Priority Program ”PlanetMag”, it also provides an overview of the most recent research in the field. Magnetic fields play an important role in making a planet habitable by protecting the environment from the solar wind. Without the geomagnetic field, for example, life on Earth as we know it would not be possible. And results from recent space missions to Mars and Venus strongly indicate that planetary magnetic fields play a vital role in preventing atmospheric erosion by the solar wind. However, very little is known about the underlying interaction between the solar wind and a planet’s magnetic field. The book takes a synergistic interdisciplinary approach that combines newly developed tools for data acquisition and analysis, computer simulations of planetary interiors and dynamos, models of solar wind interaction, measurement of ancient terrestrial rocks and meteorites, and laboratory investigations.

Magnetism is one of the basic properties of matter. Mankind has trav elled a long road in discovering and utilizing magnetism, and in this respect the ancient Chinese people have made outstanding contribu tions. In the book 'Lu's Spring and Autumn', written near the end of the Warring States Period, i. e. in the third century B. C. , there is a statement on the "attraction of iron by lodestones". So at that time it was known that magnets can attract ferromagnetic material. At the be ginning ofthe first century A. D. , viz. in the early years ofthe East Hang Dynasty, the famous scholar Wang Chong wrote in his masterpiece 'Len Hen' that the handle of a magnetic dipper pointed to the south. It was thus discovered at the time that magnets can point to the poles of the geomagnetic field. At the beginning of the twelfth century, during the reign of Emperor Hui of the Sung Dynasty, in the two books written by Zhu Yo and Xu Jin, respectively, there are descriptions of the com pass used in navigation. This tells us that the application of compasses was rather widespread at that time. The distinguished scientist Sen Go (1031-1085) discovered the declination of the terrestrial magnetic field. This is four hundred and more years earlier than its discovery by Christopher Columbus in 1492 during his voyage across the Atlantic Ocean. Such facts as these manifest the important contributions of ancient China to global civilization.

When we look at a starry night sky, we are looking out through vast invisible expanses of our own Solar System. The planets, appearing as bright specks, have been revealed as worlds by space missions. However, the invisible spaces between them are equally interesting. Unseen forces, such as the effect of gravity, spiraling magnetic fields, and subatomic particles, originate from the Sun. Celestial bodies too small to see form unexpected patterns, while atoms and nuclei are hidden even if in our own bodies. Weaving the history of discovery with clear explanations, Invisible Solar System pulls back the cloak of invisibility under which myriad aspects of the local region of space are connected. Features: • Gravity, originally seen as an invisible force, is now revealed as a curvature of spacetime, and, even in its simple form, enables amazing patterns to form • The smallest particles have other structures that enable them to interact, powering the present Solar System while also giving clues to nuclear events past and present • Long-range forces of electricity and magnetism connect the Sun and planets, dominating the hot plasma gas of space while protecting us from cosmic rays via multiple layers of magnetic shields Martin Connors is a Professor of Astronomy, Mathematics, and Physics at Canada’s dominant distance education institution, Athabasca University. He is also affiliated with the planetary science group at Western University in London, Canada. He has authored numerous courses and scientific articles. His wide-ranging research has extended from the history of astronomy, through asteroids and their impact craters, to auroras and their magnetic effects. He has been a visiting professor at UCLA and at Nagoya University in Japan. When not doing scientific work, he reads about history, practices foreign languages, and blends photography with travel when possible.

The latest observation of hundreds of exoplanets and the discovery of supermassive black hole at the center of many galaxies set the foundation for the theory presented in this book. The theory suggest that the sun and stars energy source is not from fusion, but instead from magnetic fields spreads in the galaxy by the supermassive black hole at the center of every galaxy. This idea changes every aspect of astronomy and cosmology. The big bang is no longer necessary to explain the source of the mass in the universe and the expansion of the universe. According to this theory the matter in the universe is created in the cores of stars by conversion of energy to mass. The expansion of the universe is induced by the rapid formation of new galaxies. Stars grow slowly and gradually over tens of billion of years by conversion of energy to mass. The gradual growth of stars and the planet search programs that found hundreds of nearby planets indicate that stars are born from planets. This invalidates the solar nebula hypothesis as the source of the stars and the solar system. Stars fluctuate from a main sequence state to a red giant state. They stay in the main sequence when they receive strong magnetic fields and they turn into a red giant when the magnetic fields are weakened. The sun also fluctuated from a main sequence to a red giant. When the sun was a red giant it had strong solar wind that supplied the material to created the planets. The solar system contains hard evidence that the sun was a red giant, those are short lived isotopes and chondrules. The fact that there is hard evidenced to a red giant sun confirm this theory. Highlights of this theory include the following: 1. The sun energy source is from magnetic fields from the galactic center. 2. The heat induced by the magnetic fields leads to high energy collision between particle in the sun core that creates new particle and increase the sun mass. 3. All the stars in the galaxy create new mass so the total mass and the size of the galaxy is increasing. 4. The stars in the galaxy eject dust that freefall to the galactic center supermassive black hole. Thorough the dynamo effect the gravitational potential energy of the debris and dust is converted to magnetic fields. 5. As the galaxy mass and size increase, globular clusters are detached form the main galaxy to create new galaxies. 6. Galaxies spawn new galaxies and the total number of galaxies in the universe increase. 7. The universe expands and accelerates from the increase in the number of the galaxies. 8. The Big Bang cosmological model is replaced by a new cosmological model that resembles the steady state theory. 9. Stars grow gradually from conversion of energy to mass. 10.Stars are born from planets, they first grow by accretion and then by conversion of energy to mass. 11.Stars fluctuate from main sequence to a red giant. When the magnetic fields are strong the star is in the main sequence, when the magnetic fields are weakened the star turn to a red giant. 12.The sun was a red giant 4.6 billions years ago. 13.The planets were created from the strong solar wind of the red giant sun.

This volume extends the ISSI series on magnetic fields in the Universe into the domain of what are by far the strongest fields in the Universe, and stronger than any field that could be produced on Earth. The chapters describe the magnetic fields in non-degenerate strongly magnetized stars, in degenerate stars (such as white dwarfs and neutron stars), exotic members called magnetars, and in their environments, as well as magnetic fields in the environments of black holes. These strong fields have a profound effect on the behavior of matter, visible in particular in highly variable processes like radiation in all known wavelengths, including Gamma-Ray bursts. The generation and structure of such strong magnetic fields and effects on the environment are also described.
