    The long and the short of turbulence

    The formation of stars through the collapse of molecular clouds is strongly influenced by turbulence. New high-resolution hydrodynamic simulations reveal the turbulent properties of the interstellar medium from subsonic to supersonic scales, in the process providing quantitative constraints for models of turbulent star formation.

    Subsurface ice on Mars

    The SWIM project maps the likelihood of finding water ice in the shallow subsurface of Mars, which could be used for future resource utilization. By putting together information from five different detection techniques, they identify the Arcadia Planitia and Deuteronilus Mensae regions as the most promising at mid-latitudes.

    Quantum sensor networks for exotic astrophysics

    Cataclysmic astrophysical events, such as black hole mergers, could release energy in unexpected forms. Emitted exotic low-mass fields would lag behind gravitational waves and cause feeble signals in quantum sensor networks, such as the atomic clocks comprising the GPS constellation.

    Bright intruders

    The Hayabusa2 spacecraft has observed bright boulders on the surface of carbonaceous asteroid Ryugu. These boulders belong to a different body than Ryugu’s parent body and shed light on Ryugu’s collisional history. Similar bright boulders have been observed on asteroid Bennu by OSIRIS-REx.
