South Africa's MeerKAT telescope will help uncover next space frontier

MeerKAT, a 64-dish telescope, was inaugurated into the larger Square Kilometre Array instrument on Friday. When finished in the late 2020s, the network of telescopes will be able to scan the sky 10,000 times faster with 50 times the sensitivity of any other telescope.

Dawn breaks over a radio telescope dish of the KAT-7 Array pointing skyward at the South African site for the Square Kilometre Array (SKA) telescope near Carnavon in the country's remote Northern Cape province, South Africa, on May 18, 2012. MeerKAT, a radio telescope with 64 dishes, was inaugurated into the SKA project on Friday.

A scientific mega-project to unlock cosmic conundrums from dark energy to detecting extraterrestrial life was given a boost on Friday, when the 64-dish MeerKAT radio telescope was inaugurated in the remote South African town of Carnarvon.

Built at a cost of 4.4 billion rand, MeerKAT will be incorporated into the complex Square Kilometre Array (SKA) instrument, which when fully operational in the late 2020s would be the world’s biggest and most powerful radio telescope.

Up to 3,000 dishes co-hosted in Africa and Australia will then be able to scan the sky 10,000 times faster with 50 times the sensitivity of any other telescope and produce images that exceed the resolution quality of the Hubble Space telescope, scientists said of SKA.

"MeerKAT will address some of the key science questions in modern astrophysics – how did galaxies form, how are they evolving, how did we come to be here ... and for those purposes MeerKAT is the best in the world," said Fernando Camilo, chief scientist at the South African Radio Astronomy Observatory which built and operates the telescope.

At an inauguration attended by government officials and foreign dignitaries, Mr. Camilo released new images taken by MeerKAT of the region surrounding the supermassive black hole at the center of the Milky Way galaxy, some 25,000 light years away.

"We didn’t expect to use our telescope so early in the game, it’s not even optimized, but to turn it to the center of the galaxy and obtain these stunning images, the best in the world, tells you you’ve done something right, better than right,” he told Reuters.

MeerKAT is a followup to the KAT 7 (Karoo Array Telescope), built in the vast semi-desert Karoo region north of Cape Town to demonstrate South Africa's ability to host the SKA. Its name is a play on words: in Afrikaans "meer" means "more," as in "more KAT," but it also refers to the small mammal native to the Karoo and famed for standing on its hind legs to view the world.

Besides groundbreaking astronomy research, MeerKAT is also pushing boundaries in big data and high-performance computing with the likes of IBM helping develop systems able to handle the dizzying amount of data fed from each individual antenna to supercomputers buried deep underground to limit radio interference.

The biggest radio telescope of its kind in the southern hemisphere, MeerKAT looks like a cluster of eggs when you first see it about an hour’s drive outside Carnarvon.

But up close, each sensitive dish is almost as high as a three story building, rotating on a fixed pedestal as it scans the sky. Chosen because of its remoteness, with hills providing an extra shield against radio interference, the project site is the main African base for hundreds of antennae that will eventually be placed as far as Kenya and Ghana.

"The first phase of SKA 1 in South Africa is to add 133 antennas to that [of MeerKAT]," said Rob Adam, an SKA international board member.

The expansion is expected to start next year, said Mr. Adam, with the first prototype dish built in China already on site about 280 miles north of Cape Town in the Northern Cape province. MeerKAT will operate independently before being incorporated into SKA 1 sometime around 2023, Adam said.

What is the Monitor difference? Tackling the tough headlines – with humanity. Listening to sources – with respect. Seeing the story that others are missing by reporting what so often gets overlooked: the values that connect us. That’s Monitor reporting – news that changes how you see the world.

Dear Reader,

About a year ago, I happened upon this statement about the Monitor in the Harvard Business Review – under the charming heading of “do things that don’t interest you”:

“Many things that end up” being meaningful, writes social scientist Joseph Grenny, “have come from conference workshops, articles, or online videos that began as a chore and ended with an insight. My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier. Sometimes, we call things ‘boring’ simply because they lie outside the box we are currently in.”

If you were to come up with a punchline to a joke about the Monitor, that would probably be it. We’re seen as being global, fair, insightful, and perhaps a bit too earnest. We’re the bran muffin of journalism.

But you know what? We change lives. And I’m going to argue that we change lives precisely because we force open that too-small box that most human beings think they live in.

The Monitor is a peculiar little publication that’s hard for the world to figure out. We’re run by a church, but we’re not only for church members and we’re not about converting people. We’re known as being fair even as the world becomes as polarized as at any time since the newspaper’s founding in 1908.

We have a mission beyond circulation, we want to bridge divides. We’re about kicking down the door of thought everywhere and saying, “You are bigger and more capable than you realize. And we can prove it.”
