Research
MPS is organised in three departments: Sun and Heliosphere, Planets and Comets, and Solar and Stellar Interiors. In addition, since 2002 there is also an
International Max Planck Research School.
Subjects of research at the institute are the various objects within the Solar System. A major area of study concerns the Sun, its atmosphere, the interplanetary medium as influenced by the solar wind, as well as the impact of solar particles and radiation on the planets. The second area of research involves the interiors, surfaces, atmospheres, ionospheres, and magnetospheres of the planets and their moons, as well as of comets and asteroids.
A further essential part of the activities at the institute is the development and construction of instruments for space missions.
The analysis and interpretation of the acquired datasets are accompanied by intensive theoretical work. Physical models are proposed and then tested and further developed with the aid of computer simulations.
The Sun and heliosphere
The researchers at the MPS are studying the complete range of dynamic and often spectacular processes occurring on the Sun – from the interior to the outer heliosphere. At the heart of this research is the
magnetic field
A magnetic field (sometimes called B-field) is a physical field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials. A moving charge in a magnetic field experiences a force perpendicular ...

and causes, among other things, dark spots on the surface. Answers to the following questions are being sought: Why does the magnetic field change with an eleven-year cycle? How does the magnetic field produce the various structures on the Sun? How is the corona heated to many millions of degrees?

Ulysses have provided fundamentally new insights: Measurements of the ultraviolet spectrometer SUMER on board SOHO played a decisive role in recognizing the significance of the magnetic field for dynamic processes and Ulysses measured the three-dimensional structure of the solar wind for the first time.

Future projects will stress research into the physical causes of the Sun's variations. The ambitious
Solar Orbiter Mission, based on a suggestion from the institute, will see a probe approach our star to within a fifth of the Earth-Sun distance in order to investigate the magnetic field and its effects in the various layers of the solar atmosphere.
Planets and comets

The full transfer from Fraunhofer to Max Planck Society and the appointment of W. Dieminger as director followed by the transfer of the Max Planck Institute of Stratosphere Research from Weisenau near Ravensburg to Lindau and another renaming to "Max Planck Institute for Aeronomy" completed the built up.

Erhard Keppler became the science lead in the first German satellite
Azur (in cooperation with NASA) and with him a small group of scientists dedicated to work with satellites was established in Lindau. The institute was selected to build part of the instrumentation of the satellite which was launched in November 1969. The institute also built instruments for the
Helios probes as part of another Germany/NASA cooperation.
