Astronomers have linked up data from the 64 antennae of the MeerKAT telescope to map the cosmos on a large scale.
It used to be the case that if you wanted a powerful telescope, you had to build it big — really big. But now, it’s possible to create a very powerful telescope by using multiple smaller antennae spread over a large area, which is how projects like the Event Horizon Telescope that took the famous first image of a black hole work.
SKA is currently under construction, but before it can be used for science, the design principles need to be worked out. That’s the job of MeerKAT, an array of 64 antennae in South Africa that will eventually become part of the SKAO system. Typically, the telescopes would all work together as part of an array. But recently, astronomers at the headquarters of the SKAO at Jodrell Bank in the U.K.
