The Square Kilometre Array will be the largest radio telescope in the world, consisting of thousands of detectors working together, stretched across South Africa and Australia. This is a truly global endeavour, with ten countries around the world involved in its construction. The Square Kilometre Array is an incredible feat of engineering, comparable in scale to the Large Hadron Collider or the International Space Station. At the SKA engineering stand at bluedot in conjunction with the Royal Academy of Engineering, you can talk to SKA engineers to find out about some of the immense challenges they face, and the world-changing technology being created to overcome them. Have a go at our SKA-themed activities including: find out how the telescope signals are recorded, transported and synchronised, see the invisible with our infrared camera, and explore why telescope shapes are important using our parabolic microphones.
