MUSE and X-shooter instruments on the Very Large Telescope (VLT) at ESO’s Paranal Observatory in Chile have been used to study an ongoing collision between two galaxies, known collectively as IRAS F23128-5919, 600 million light-years from Earth. The group observed the outflows – that originate near the supermassive black hole at the heart of the pair’s southern galaxy, and have found the first clear evidence that stars are being born within them. The discovery has many consequences for understanding galaxy properties and evolution.

Such galactic outflows are driven by the huge energy output from the active and turbulent centres of galaxies...
