Gigamaser: The Universe’s Brightest Microwave Laser Detected in Deep Space
TL;DR Summary
Astronomers using the MeerKAT radio telescope spotted an extremely bright hydroxyl maser in the distant galaxy merger H-ATLAS J142935.3–002836, whose signal was amplified by an unrelated foreground galaxy acting as a gravitational lens, yielding the first gigamaser—about 100,000 times the luminosity of a star—and enabling new ways to probe cosmic evolution from billions of light-years away.
