Astronomers Using MeerKAT Spot a Cosmic Laser Halfway Across the Universe​


The Universe is full of surprises, including a fascinating type of "space laser" known as Mega-Microwave Amplification by Stimulated Emission of Radiation (megamasers). More specifically, hydroxyl megamasers (OHMs) are extremely bright radio-wavelength emissions produced when gas-rich galaxies collide. This compresses the gas and stimulates large reservoirs of hydroxyl molecules (-OH) to amplify radio emissions. Using the MeerKAT radio telescope in South Africa, astronomers discovered a hydroxyl megamaser located in a violent galactic merger more than 8 billion light-years away.
