discovered by astronomers.<\/p>\n<p>The beam of radio waves is what scientists call a \u201cmegamaser\u201d and this one is the most distant yet, emerging 5 billion light-years from Earth.<\/p>\n<p>It was detected by an international team of scientists using South Africa\u2019s \u201cMeerKAT,\u201d a radio telescope consisting of 64 antennas.<\/p>\n<p>Megamasers are naturally occurring, radio-wavelength lasers that can help shed light on galaxy collisions.<\/p>\n<p>\u201cMegamasers act like bright lights that say: Here is a collision of galaxies that is making new stars and feeding massive black holes,\u201d said study co-author Jeremy Darling, of the University of Colorado.<\/p>\n<p>When galaxies merge, the gas they contain becomes extremely dense, producing a specific radio signal known as a maser.<\/p>\n<p>Megamasers are powerful masers produced in huge galaxy collisions, like beams from cosmic lighthouses.<\/p>\n<p>The unearthing of the most distant megamaser to date was described by Darling and colleagues in a research paper published last week.<\/p>\n<p>To reflect its status as a record-breaking, the team named the space laser Nkalakatha \u2013 an isiZulu word meaning \u201cbig boss\u201d.<\/p>\n<p>\u201cNkalakatha is one\u00a0of the most powerful OH megamasers known, and it\u2019s the most distant megamaser\u00a0of its kind ever discovered, so it is truly a \u2018big boss,\u2019\u201d said study coauthor and Rutgers University astronomer Professor Andrew Baker.<\/p>\n<p>\u201cWe expect it is\u00a0only the first of many OH [hydroxyl] megamasers that will be discovered as the project continues.\u201d<\/p>\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" loading=\"lazy\" width=\"1024\" height=\"682\"

Images<\/span><\/figcaption><\/figure>\n<p>Rather than emitting visible light, a maser emits microwave and radio wavelengths that are amplified by cosmic forces.<\/p>\n<p>Once the team established that they had a megamaser on their hands, they began the hunt for the galaxy it came from.<\/p>\n<p>They found that the Nkalakatha galaxy is about seven billion light-years away and has a long tail on one side, visible in radio waves.<\/p>\n<p>The light from the megamaser was emitted about five billion years ago when the universe was only two-thirds of its current age.<\/p>\n<p>The main goal of the MeerKAT project is to use make observations of gas in\u00a0distant galaxies to help understand how galaxies have evolved over the last nine billion years.<\/p>\n<p>Because these radio signals are faint, the researchers aim to obtain thousands of hours of observations with MeerKAT\u00a0to\u00a0detect them.<\/p>\n<p>The data are crunched by powerful computers to help unearth signs of distant and ancient objects of interest.<\/p>\n<p>\u201cMeerKAT will probably double the known number of these rare phenomena,\u201d Darling said.<\/p>\n<p>\u201cGalaxies were thought to merge more often in the past, and the newly discovered OH megamasers will allow us to test this hypothesis.\u201d<\/p>\n<p><em>This story originally <a
