Astronomers Detect 8 Billion-Light-Year Gigamaser, Setting Distance and Power Records
1 articles · Updated · Boy Genius Report · May 11
A microwave maser 8 billion light-years away has been identified as the farthest and most powerful of its kind, bright enough for researchers to classify it as a new category: a gigamaser.
A near-perfect alignment with an intervening galaxy gravitationally magnified the signal from HATLAS J142935.3–002836, turning what would normally be too faint to see into a detectable beam.
MeerKAT in South Africa captured the signal from the merging galaxy, with astronomers processing roughly 2.5 terabytes of radio data per hour to isolate the 7-inch-wavelength emission.
Hydroxyl masers arise in violent galaxy mergers that compress gas, trigger starbursts and feed supermassive black holes, making them a tool for tracing how galaxies formed and evolved.
The newly found source is about 100,000 times as luminous as a star, and the team says similar searches could uncover hundreds to thousands more such objects.
This 'cosmic laser' was found by chance. What other secrets of the universe are waiting for a lucky alignment to be revealed?
A galactic crash 8 billion years ago created this signal. What can this ancient, violent event teach us about our own galaxy's birth?
Record-Breaking 8-Billion-Light-Year Gigamaser Reveals Secrets of the Early Universe
Overview
In March 2026, scientists used the MeerKAT radio telescope in South Africa to discover HATLAS J142935.3–002836, the most distant and powerful gigamaser ever found, located 8 billion light-years away. This cosmic microwave laser shines a billion times brighter than typical masers in our galaxy, revealing that extremely luminous systems already existed in the early universe. The discovery was made possible by gravitational lensing, where a foreground galaxy magnified the gigamaser's signal. This breakthrough offers a unique glimpse into the universe’s past and highlights MeerKAT’s ability to explore distant, energetic cosmic phenomena.
