![]() Rather than emitting visible light, a maser emits microwave and radio wavelengths that are amplified by cosmic forces. “We expect it is only the first of many OH megamasers that will be discovered as the project continues.” A general view of one of a 64-dish radio telescope system is seen during an official unveiling ceremony on July 13, 2018, in Carnarvon. “Nkalakatha is one of the most powerful OH megamasers known, and it’s the most distant megamaser of its kind ever discovered, so it is truly a ‘big boss,’” said study co-author and Rutgers University astronomer Professor Andrew Baker. To reflect its status as a record-breaker, the team named the space laser Nkalakatha - an isiZulu word meaning “big boss.” Galaxy Arp 220 as imaged by the Wide Field Planetary Camera on the Hubble Space Telescope. The unearthing of the most distant megamaser to date was described by Darling and colleagues in a research paper published last week. Megamasers are powerful masers produced in huge galaxy collisions, like beams from cosmic lighthouses. When galaxies merge, the gas they contain becomes extremely dense, producing a specific radio signal known as a maser. “Megamasers act like bright lights that say: Here is a collision of galaxies that is making new stars and feeding massive black holes,” said study co-author Jeremy Darling, of the University of Colorado. Megamasers are naturally occurring, radio-wavelength lasers that can help shed light on galaxy collisions. It was detected by an international team of scientists using South Africa’s “MeerKAT,” a radio telescope consisting of 64 antennas. The beam of radio waves is what scientists call a “megamaser” and this one is the most distant yet, emerging 5 billion light-years from Earth.
