This artist’s impression shows two neutron stars at the point at which they merge and explode as a kilonova. Such a very rare event is expected to produce both gravitational waves and a short gamma-ray burst, both of which were observed on August 17, 2017, by LIGO and Virgo collaborations.

False-color near-infrared image of the core of the young massive cluster RCW 38 taken with the adaptive-optics camera NACO on ESO’s Very Large Telescope. RCW 38 lies at a distance of about 5,500 light years from the Sun. The field of view of the central image is approximately 1 arc minute, or 1.5 light-years across. The insets, each spanning about 0.07 light-years on a side, show a subset of the faintest and least massive cluster candidate brown dwarfs (indicated by arrows) of RCW 38 discovered in this new image.

Schematic representation of rotating disc galaxies in the early Universe (right) and the present day (left). New VLT observations suggest that such massive star-forming disc galaxies in the early Universe were less influenced by dark matter (shown in red), as it was less concentrated. As a result the outer parts of distant galaxies rotate more slowly than comparable regions of galaxies in the local Universe. Image credit: ESO / L. Calçada.
