Abstract: In 2021, we found in the LADUMA (looking at the distant Universe with the MeerKAT Array) survey the telltale signature of Hydroxyl (Oxygen-Hydrogen atom) emitting coherent radio light. The process is known as "masing", similar to how a laser works but occurring naturally and in the radio. Based on suggestions from the public, we nicknamed "Nkalakata" (Big Boss in Zulu). We are now pointing more telescopes at this most distant galaxy to understand how masers could happen naturally and what they tell us about the galaxies they occur in.
