- The MeerKAT Radio Telescope detected a powerful cosmic “gigalaser” (hydroxyl megamaser) located about 8 billion light-years from Earth.
- A Megamaser is a natural cosmic source that amplifies microwave or radio waves through stimulated emission of radiation.
- The signal was produced by hydroxyl (OH) molecules in a distant galaxy during galaxy collisions and mergers.
- The radio signal was magnified by Gravitational Lensing, where a massive galaxy bends and amplifies light from a distant source.
- The MeerKAT Radio Telescope is located in South Africa and is part of the Square Kilometre Array (SKA) radio astronomy project.
