A new, bright green comet, officially designated Comet C/2025 F2 (SWAN), has been discovered by an amateur astronomer. It was spotted by Michael Mattiazo using imagery from SWAN, an instrument on the European Space Agency’s SOHO spacecraft, in late March. It is now visible from the UK and elsewhere and will remain so until around 14 April.
