FEATURE - Clouds of Hydrogen Gas ? Simon Tang Clouds of hydrogen gas give way as the magnetic field lines of the sun snap and clash together. This display of nature creates astonishing features, known as prominences, on the limb of the Sun. Taken with QHYCCD QHY5III-174M camera, 5040mm f/33.6, 1000 x 12-millisecond frame exposures Location: Los Angeles, California, United States

Image of the broken fragments surrounding Fragment B of Comet 73P/Schwassmann-Wachmann 3 observed with FORS1 on ESO's VLT in four filters (B, V, R, and I). As the telescope was tracking the comet, the stars appear as coloured trails, indicating the order in which the comet was observed in the different filters. North is up and East is to the left.

This image shows the Atacama Large Millimeter/submillimeter Array (ALMA) looking up at the Milky Way as well as the location of Sagittarius A*, the supermassive black hole at our galactic centre. Highlighted in the box is the image of Sagittarius A* taken by the Event Horizon Telescope (EHT) Collaboration. Located in the Atacama Desert in Chile, ALMA is the most sensitive of all the observatories in the EHT array, and ESO is a co-owner of ALMA on behalf of its European Member States.

This artist???s impression shows a two-star system where micronovae may occur. The blue disc swirling around the bright white dwarf in the centre of the image is made up of material, mostly hydrogen, stolen from its companion star. Towards the centre of the disc, the white dwarf uses its strong magnetic fields to funnel the hydrogen towards its poles. As the material falls on the hot surface of the star, it triggers a micronova explosion, contained by the magnetic fields at one of the white dwarf???s poles.
