A new radio telescope operating at just a quarter of its full power is revealing the universe\u2019s secrets one image at a time.<\/p>\n<p>MeerKAT will ultimately become part of the Square Kilometre Array (SKA) telescope.<\/p>\n<p>Once it\u2019s completed some time in the decade following 2020, the SKA will be the <strong><a href=\"http:\/\/www.space.com\/15883-worlds-largest-radio-telescope-ska-array.html\" target=\"_blank\">world\u2019s largest radio telescope<\/a><\/strong>.<\/p>\n<p>The project is shared between South Africa and Australia. It\u2019s not just its size that sets it apart from other radio telescopes but also sensitivity and speed.<\/p>\n<p>At full power, the SKA <strong><a href=\"http:\/\/www.space.com\/15883-worlds-largest-radio-telescope-ska-array.html\" target=\"_blank\">will have<\/a><\/strong> 50 times the sensitivity and 10,000 times the survey speed of the best existing telescopes.<\/p>\n<p>It will see more, and see it faster. It can explore the universe and answer some of humanity\u2019s biggest scientific questions \u2013 like, \u201cIs there life out there?\u201d and \u201cHow are galaxies formed?\u201d<\/p>\n<p>All of this lies some time in the future. But already, MeerKAT is yielding remarkable results.<\/p>\n<p><a href=\"http:\/\/mygaming.co.za\/news\/wp-content\/uploads\/2016\/09\/Merkat-01.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-106075\" src=\"http:\/\/mygaming.co.za\/news\/wp-content\/uploads\/2016\/09\/Merkat-01.png\" alt=\"merkat-01\" width=\"754\" height=\"754\" srcset=\"https:\/\/mygaming.co.za\/news\/wp-content\/uploads\/2016\/09\/Merkat-01.png 754w, https:\/\/mygaming.co.za\/news\/wp-content\/uploads\/2016\/09\/Merkat-01-110x110.png 110w, https:\/\/mygaming.co.za\/news\/wp-content\/uploads\/2016\/09\/Merkat-01-100x100.png 100w\" sizes=\"auto, (max-width: 754px) 100vw, 754px\" \/><\/a><\/p>\n<p>MeerKAT currently comprises 16 dishes (of an eventual 64) functioning as a telescope array \u2013 a radio telescope works by effectively linking smaller dishes together and operating as one.<\/p>\n<p>These 16 dishes, known collectively as Array Release 1, recently embarked on their first assignment.<\/p>\n<p>It was an amazing start: Array Release 1 found 1300 galaxies in a patch of sky that was previously thought to contain only 70.<\/p>\n<p>That\u2019s hundreds of new galaxies to be studied and understood, and greatly adds to our knowledge of the universe.<\/p>\n<figure class=\"align-center \"><figcaption><\/figcaption><\/figure>\n<p>Because MeerKAT specialises in radio galaxies, it can peer through the thick layers of dust that surround such galaxies.

It takes remarkable engineering to bring any radio telescope to life, let alone what will become the world\u2019s largest.<\/p>\n<p>Each of MeerKAT\u2019s completed 64 dishes will be 13.5 metres, or about 40 feet, in diameter. The dishes are accompanied by a plethora of cryogenic coolers, receivers, digitisers and other electronic systems.<\/p>\n<p>t\u2019s a challenge to get all of this equipment to work together in a fully integrated array. That\u2019s why the telescope is being commissioned in phases: it allows any technical problems to be identified and resolved as early as possible.<\/p>\n<p>As the \u201cfirst light\u201d images reveal, everything is functioning smoothly as the MeerKAT begins its sky-searching work.<\/p>\n<h2 class=\"my-4\">Space for science in action<\/h2>\n<p>One of the important features of the SKA and MeerKAT is that it\u2019s a massive, multinational endeavour. There are around 200 technicians, scientists and engineers working on the project. They come from all over the world and are collaborating with industry to build the technologies, hardware and software systems for MeerKAT telescope.<\/p>\n<p>It\u2019s not just about the construction, though. Scientists are also getting the chance to test their theories using MeerKAT\u2019s infrastructure.<\/p>\n<p>I am part of a team led by <a href=\"https:\/\/www.uwc.ac.za\/Biography\/Pages\/Mario-Santos.aspx\">Professor Mario Santos<\/a> of the University of the Western Cape involved in a large survey that will be conducted with MeerKAT. The team consists of scientists from South African and international institutions. Our goal is to do breakthrough cosmology and study the many new galaxies that will be detected.<\/p>\n<p>Recently a new scientific technique called <a href=\"http:\/\/www.caastro.org\/research\/evolving\/intensitymapping\">HI Intensity Mapping<\/a> has emerged as a powerful and promising probe for cosmology with radio telescopes. It involves trying to map the universe\u2019s neutral hydrogen content.<\/p>\n<p>MeerKAT provides an exciting opportunity to put this science to the test. We\u2019re seeking an extremely weak signal, much weaker than the galaxy and the contributions that the instrument adds to the data. My recent work has involved demonstrating that you can \u201cclean\u201d out all these other contributions to access the very weak hydrogen signal. Once we\u2019re able to locate this crucial signal, we\u2019ll be able to understand much more about the universe.<\/p>\n<h2 class=\"my-4\">Staring at the sky<\/h2>\n<p>It\u2019s not just those who are directly involved in the project who are excited about what MeerKAT has to offer. Just after Array Release 1, about 150 astronomers \u2013 two thirds of them from South Africa \u2013 <a href=\"http:\/\/meerkat2016.ska.ac.za\/programme\">met<\/a> to discuss and update the MeerKAT science programme in Stellenbosch.<\/p>\n<p>Broadly, this programme will consist of two major elements. The first involves approved large surveys of the sky. These will peer into deep space; they\u2019ll range from shallow and wide to deep and small, covering large volumes of space containing many, many galaxies. The images they\u2019ll capture will deepen our understanding of what the universe contains, how it\u2019s structured and how it works.<\/p>\n<p>The second element is open time: time reserved for astronomers to propose new and interesting observations that can then be conducted using the MeerKAT. This encourages more research and could lead to even more of the universe\u2019s secrets being revealed.<\/p>\n<h2 class=\"my-4\">Much more to come<\/h2>\n<p>The \u201cfirst light\u201d images are just the beginning.
