china has completed commissioning of the world’s largest and most sensitive radio telescope following a productive three-year trial. the spherical telescope, or FAST for short, will help to uncover the mysteries of space surrounding the genesis and evolutions of the universe, in other words: it will look for aliens (among other things).

it will be used to look for pulsars, highly magnetized rotating neutron stars that emit beams of electromagnetic radiation. since 2017, it has already discovered two and has since discovered a total of 102 in just over two years. according to a press release, fast’s development involved relocating 7,000 residents in the vicinity. it notes that ‘an astronomy-themed park has been built around the site of fast, drawing a large number of visitors and tourists.’
