The largest fully steerable radio telescope in the world is the Robert C. Byrd Green Bank Telescope (GBT) in West Virginia, USA. This massive telescope has a diameter dish of 100 metres (328 feet). It is so sensitive that it can detect signals as faint as a billionth of a billionth of a watt, allowing astronomers to observe incredibly distant and faint objects in the universe. Additionally, the entire structure can be rotated and tilted to point at any part of the sky, making it incredibly versatile for various astronomical studies.
Radio telescopes can be used to be linked together to form a single, massive virtual telescope through a technique called Very Long Baseline Interferometry (VLBI). This technique allows radio telescopes located thousands of kilometres apart to work in unison, effectively creating a telescope the size of the distance between them. One of the most remarkable achievements using VLBI was the Event Horizon Telescope (EHT) project, which linked radio telescopes around the world to capture the first-ever image of a black hole in 2019. This groundbreaking image of the supermassive black hole at the centre of the galaxy M87 provided direct visual evidence of a black hole’s existence.
