Space physics is the study of the natural phenomenon that occur in our solar system. Specifically, the sun, the particles and radiation it creates and how these affect the planets. This includes the solar wind and its interaction with the Earth and near-Earth space; so-called space weather.
Coordinated observations between the Hubble Space Telescope and ground-based telescopes of a star that is an analogue of the young Sun have uncovered multi-temperature signatures of stellar coronal mass ejections. The detection of fast–warm and slow–cool plasma components suggests a solar-like but more complex picture of stellar eruptions, with impact on the planets around young stars.
Coordinated ground- and space-based observations of a solar flare reveal synchronized quasi-periodic pulsations in downflowing chromospheric plasma, resulting from electron acceleration modulated by repeated magnetic reconnection.
Jupiter’s magnetodisk mediates mass, momentum, and energy exchange between Jupiter’s atmosphere, ionosphere, magnetosphere, and moon tori. Here, the authors show that pressure anisotropy-driven instabilities regulate its nonequilibrium dynamics.
Earlier this month we celebrated the 30th anniversary of the detection of the first planet outside our Solar System orbiting a Sun-like star. This discovery triggered the birth of a field in astronomy that hasn’t stopped growing or producing surprises.

The importance of small bodies in Solar System studies is not proportional to their size. Due to their variety of types, scope, and link to Solar System formation, they are one of the most active fields in planetary science.
