Left: the William Herschel telescope with the WEAVE instrument. The WEAVE fibre positioner is located in the 1.8-metre black box on the upper ring. Optical fibres run through the telescope structure to the platform on the left, which houses the spectrograph. Credit: Sebastian Kramer. Right: image of the James Webb Space Telescope (JWST) from Stephan’s quintet, with the outline of the WEAVE LIFU pointing for the first-light observation. Each circle indicates an optical fibre 2.6 arcseconds in diameter. The observation provides physical information on the different regions of each of the galaxies, as well as their immediate surroundings, spanning 120 000 light-years from one end to the other.
