The winners of the ZWO Astronomy Photographer of the Year 2025 will be revealed live online on Sept. 11 and you can follow along for free thanks to a livestream hosted by the Royal Observatory Greenwich starting at 2 p.m. ET (1800 GMT) on Sept. 11.
Each year, the Royal Observatory, supported by astronomy camera and accessory manufacturer ZWO, holds an open competition to celebrate the very best images of the night sky as captured by the global astrophotography community. Categories span everything from galaxies and nebulas to auroras, the sun and 'People & Space,' with winners and runners-up chosen by an international judging panel.
