This artist’s concept visualizes a kilonova – an explosion that happens when two neutron stars or a neutron star and a black hole collide and merge. When these collisions happen, a fraction of the resulting debris is ejected as jets, which move near the speed of light. The remaining debris produces hot, glowing, neutron-rich clouds that forge heavy elements, like gold and platinum. Researchers will mine data from NASA’s Nancy Grace Roman Space Telescope, which will survey the same areas of the sky every few days, to identify kilonovae. Roman’s extensive data will help astronomers better identify how often these events occur, how much energy they give off, and how near or far they are.

This image shows a detailed, thousand-colour image of the Sculptor Galaxy captured with the MUSE instrument at ESO’s Very Large Telescope (VLT). Regions of pink light are spread throughout this whole galactic snapshot, which come from ionised hydrogen in star-forming regions. These areas have been overlaid on a map of already formed stars in Sculptor to create the mix of pinks and blues seen here.

Nut’s cosmological vignette on the outer coffin of Nesitaudjatakhet in the collection of Odessa Archaeological Museum OAM 52976 (C107). Nut’s body is covered in stars as well as a thick, undulating black curve that runs from the soles of her feet to the tips of her fingers. This curve, surrounded by stars on both sides, is reminiscent of the Milky Way’s Great Rift. Credit: Mykola Tarasenko; Odessa Archaeological Museum, NASU

The Giant Metrewave Radio Telescope imaged these giant radio jets stretching 6 million light-years across with an enormous supermassive black hole at the heart of spiral galaxy J23453268-0449256. Could this cosmic anomaly hint at the future of our own Milky Way galaxy? Image via Bagchi and Ray et al/ Giant Metrewave Radio Telescope/ Royal Astronomical Society/

This collage highlights a small selection of regions of the Milky Way imaged as part of the most detailed infrared map ever of our galaxy. Here we see, from left to right and top to bottom: NGC 3576, NGC 6357, Messier 17, NGC 6188, Messier 22 and NGC 3603. All of them are clouds of gas and dust where stars are forming, except Messier 22, which is a very dense group of old stars.

The central region of a spiral galaxy. Its core is a small bright point radiating bright, bluish-white light over the scene. The white light is diffuse and many point-like stars in the galaxy (and even background galaxies) can be seen through it. The galaxy’s arms can be seen as broad, swirling streaks of glowing gas and dust, coloured red and orange. Two additional arms are revealed in green

An artist’s concept of the Milky Way, which is a spiral galaxy that has a defined center. The spiral arms are made up of stars that can be wound tightly or loosely.
