    A double neutron star merger gave rise to the gravitational-wave event GW 180817, with counterpart electromagnetic radiation in the optical and gamma-ray spectra. Polarization measurements of the optical emission reveal a lanthanide-rich macronova.

    Mapping the optical emission of a galaxy cluster to its mass is challenging. Lensing of the cosmic microwave background by massive clusters is used to calibrate the optical richness of clusters to their total baryonic mass at the ten per cent level.

    The origin of the broad-line emission from type-1 active galactic nuclei is unclear. Calculations of emission lines from dusty clumps that are tidally disrupted by the central black hole suggest that these clumps give rise to the broad-line emission.

    The authors detect hard X-ray emission produced by plasma heated at ≥10 million kelvin from a quiescent active region of the Sun, providing clear observational evidence of plasma heating by nanoflares, and hinting at their important role in coronal heating.

    Experiments are presented that indicate that methane can be produced abiotically on Mars through the photocatalytic reaction of CO2, in a process called methanogenesis. Methane can then be shocked (through impacts) to form RNA nucleobases and glycine.

    The relatively unexplored southwestern region of the Large Magellanic Cloud is host to a massive, embedded star-forming complex that rivals the star-forming efficiency of 30 Doradus. Its most luminous object could be a super star cluster in formation.

    The first extraterrestrial detections of a member of the organohalogen family of molecules have been made towards comet Churyumov–Gerasimenko and low-mass protostar IRAS 16293-2422. Chloromethane, considered to be a biomarker, can form efficiently abiotically.

    Complex organics are now observed throughout the Universe, forming in the circumstellar environments over thousands of years and providing materials for star formation. Did the Earth inherit any of these organics at the time of its formation?
