William Herschel Telescope Enhanced Area Velocity Explorer (WEAVE) wide-field spectrograph captured an amazing collision of galaxies in its first observation. NGC 7318b was traveling at 2 million mph (3.2 million km/h) this all happened in Stephan's Quintet, a galaxy group made up of 5 galaxies

WEAVE data overlaid on a James Webb Space Telescope image of Stephan's Quintet, with green contours showing radio data from the Low Frequency Array (LOFAR) radio telescope. The orange and blue colours follow the brightness of Hydrogen-alpha obtained with the WEAVE LIFU, which trace where the intergalactic gas is ionised. The hexagon denotes the approximate coverage of the new WEAVE observations of the system, which is 36 kpc wide (similar in size to our own galaxy, the Milky Way).
