The signal, deemed the most distant hydroxyl megamaser ever detected, was intercepted by the MeerKAT radio telescope in South Africa, which features 64 antennas. A hydroxyl megamaser is a giant natural laser in space. When galaxies full of gas collide, molecules called hydroxyl smash together and release very strong radio waves.
