HOW DOES THE EVENT HORIZON TELESCOPE WORK?
The Event Horizon Telescope (EHT) is often referred to as an ‘Earthsized telescope’ and as a ‘virtual telescope’. In astronomy, the bigger the telescope, the better. An amateur’s telescope with a 60mm lens will show you a decent view of the Moon’s surface or even Jupiter and Saturn, whereas the Hubble Space Telescope’s 2.4m mirror produces stunning images of nebulae and galaxies. Meanwhile, the primary mirror of the upcoming Earth-based Extremely Large Telescope is 39m across, allowing scientists to study the planets around distant stars.
