The Astronomy Photographer of the Year Awards features thousands of entries from countries all across the world. Space correspondent Dr Alfredo Carpineti takes us to The Royal Observatory, Greenwich, and speaks to Dr Ed Bloomer, one of the judges, to get some top tips and give you the edge in this incredible international competition.
Entries to both the Astronomy Photographer of the Year 15 competition and the Astronomy Photographer of the Year 15 Young close at midday (GMT) on Friday 3 March 2023.
