This image of the ‘jellyfish’ galaxy JO204 shows clearly how material is streaming out of the galaxy in long tendrils to the lower-left; red shows the glow from ionized hydrogen gas and the whiter regions are where most of the stars in the galaxy are located; some more distant galaxies are also visible.

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.

This VLT image shows the spiral galaxy NGC 1055. This large galaxy appears to lack the whirling arms characteristic of a spiral, as it is seen edge-on; however, it displays odd twists in its structure that were probably caused by an interaction with a large neighboring galaxy, Messier 77. The VLT observed NGC 1055 with the FOcal Reducer and low dispersion Spectrograph 2 (FORS2) instrument using visible-light filters. Image credit: ESO.

This artist’s view shows how the light coming from the surface of a strongly magnetic neutron star (left) becomes linearly polarized as it travels through the vacuum of space close to the star on its way to the observer on Earth (right). The polarization of the observed light in the extremely strong magnetic field suggests that the empty space around the neutron star is subject to a quantum effect known as vacuum birefringence. The magnetic and electric field directions of the light rays are shown by the red and blue lines. Image credit: L. Calçada / ESO.

This image shows the Lyman-alpha blob LAB-1. This picture is a composite of two different images taken with the FORS instrument on ESO’s Very Large Telescope - a wider image showing the surrounding galaxies and a much deeper observation of the blob itself at the center made to detect its polarization. The intense Lyman-alpha ultraviolet radiation from LAB-1 appears green after it has been stretched by the expansion of the Universe during its long journey to Earth. These new observations show for the first time that the light from this object is polarized. This means that the giant ‘blob’ must be powered by galaxies embedded within the cloud. Image credit: M. Hayes / ESO.
