Glimmering with colour and light against a pitch-black sky, this ring was seen during the eclipse that took place on 21 August 2017 across the USA. This event was a total solar eclipse, meaning that the Moon slipped perfectly in front of the Sun and blocked the entirety of the star’s light – an occurrence known as totality – for a band of observers across the country.
