    “…This book serves as a wonderful primer for anybody interested in our planet’s geological past and that of other planets in our Solar System and beyond. It illustrates not only how our planet’s surface evolved, but also how granite played a pivotal role in the creation of complex, intelligent life on Earth. …”

    “…This is precisely the dynamics that allows such theories to pass existing observational tests at scales where general relativity has been tested with exquisite precision (e.g. solar system scales). We consider here the mildly-non-linear scales of a dark matter component coupled to a galileon-type field and focus in particular on the case of a $k_{\rm V}$ < $k_{\rm NL}$ hierarchy. …”

    “…A series of non-proteinogenic amino acids, most of them found quite commonly in the meteorites known as carbonaceous chondrites, were subjected to solid state radiolysis in vacuum to a total radiation dose of 3.2 MGy corresponding to 23% of the total dose expected to be taken by organic molecules buried in asteroids and meteorites since the beginning of the solar system 4.6 × 10(9) years ago. The radiolyzed amino acids were studied by FT-IR spectroscopy, Differential Scanning Calorimetry (DSC) and by polarimety and Optical Rotatory Dispersion (ORD). …”

    “…The presence of seifertite, one of the high-pressure polymorphs of silica, in achondritic shocked meteorites has been problematic because this phase is thermodynamically stable at more than ~100 GPa, unrealistically high-pressure conditions for the shock events in the early solar system. We conducted in situ x-ray diffraction measurements at high pressure and temperatures, and found that it metastably appears down to ~11 GPa owing to the clear difference in kinetics between the metastable seifertite and stable stishovite formations. …”

    “…Earth-based radar astronomical observations provide information on surface characteristics, orbits, and rotations for a wide variety of solar system objects. Based on compound radio telescopes, both the Chinese VLBI (Very Long Baseline Interferometry) network (CVN) and the Russian VLBI network (Quasar), in cooperation with the Chinese radar transmitters, we present the current ground radar astronomical observations of the moon. …”

    “…Strong flares and coronal mass ejections (CMEs), launched from [Formula: see text]-sunspots, are the most catastrophic energy-releasing events in the solar system. The formations of [Formula: see text]-sunspots and relevant polarity inversion lines (PILs) are crucial for the understanding of flare eruptions and CMEs. …”
