Distant Galaxy Collision Yields Brightest Gigamaser Yet

Astronomers using the MeerKAT radio telescope have detected the brightest and most distant hydroxyl gigamaser, produced when gas in colliding galaxies stimulates hydroxyl molecules to emit intense microwaves. The signal, traveling about 7.8–8 billion light-years, is magnified by a foreground galaxy acting as a gravitational lens, making it appear exceptionally bright. The discovery advances study of high-redshift OH megamasers and galaxy mergers and is published (preprint available) in Monthly Notices of the Royal Astronomical Society Letters.

Cosmic Space Laser: Gigamaser Detected in Distant Galaxy

Astronomers using the MeerKAT radio telescope detected a record-breaking microwave laser (a gigamaser) in a galaxy about 8 billion light-years away, magnified by gravitational lensing. The emission, arising from excited hydroxyl molecules during a galaxy merger, is roughly 100,000 times the luminosity of a star and is the most powerful maser yet observed. Upgrades to MeerKAT could uncover hundreds to thousands more such megamasers, offering insight into conditions in the distant universe.

Gigamaser: The Universe’s Brightest Microwave Laser Detected in Deep Space

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.

Masers Rise Again: From Microwave Marvel to Room-Temperature Quantum Possibility

Masers are the microwave cousins of lasers that power cryogenic amplifiers for deep-space signals, provide precise timekeeping with hydrogen and cesium clocks, and appear in natural astrophysical sources; advances in new materials could enable room-temperature masers and even chip-scale devices for quantum computing, signaling a potential revival beyond their historical role.
