A searing solar prominence extends outwards from the surface of the Sun. The ‘wall of plasma’ is the height of three times the Earth’s diameter. This image, by Eric Toops of the United States, is one of those shortlisted in this year’s Insight Astronomy Photographer of the Year competition.
The winners of the competition’s nine categories and two special prizes will be announced on Thursday 15th September at a special award ceremony at the Royal Observatory Greenwich. A free exhibition featuring the winning images will open at the Observatory’s Astronomy Centre on Saturday 17 September.
A record number of more than 4500 entries were received from astrophotographers in over 80 countries.
