Space physics

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.

    Using large-aperture Cherenkov telescopes, Benbow et al. have measured the angular sizes of two stars through timely occultations by asteroids, achieving an order of magnitude improvement in resolution over the lunar occultation method.

    An intensification of the 7.8-µm methane emission at Jupiter’s poles is observed in coincidence with the arrival of a solar-wind compression in January 2017, highlighting the strong coupling between Jupiter’s magnetosphere and its neutral stratosphere.

    High-precision polarization observations of the binary star system Spica reveal that the amount of light from the primary component that is reflected off the secondary component (and vice versa) is a few per cent of the incident light. Such observations will be useful in identifying close binary systems.

    Farside solar magnetograms are generated from STEREO images using deep learning, with Hale-patterned active regions being well reproduced. These images can be used to monitor the temporal evolution of magnetic fields from the farside to the frontside.

    Magnetic cavities are universal phenomena existing in cosmic plasma environments. Here Liu et al. show electron scale magnetic cavities in proton scale magnetic cavities observed by Magnetospheric Multiscale (MMS) spacecraft in the Earth’s magnetosheath, and depict the boundary of the electron scale magnetic cavity using particle sounding technique.
