Judging for this year's Insight Astronomy Photographer of the Year Awards 2015 will take place next week.
With more entries than ever, it will be far from an easy task.
This year's competition has seen over 2,700 entries from over 60 countries across the globe.
It is the awards seventh year, and it has been newly expanded to cover the full breadth of what astronomy photography can offer.
The task of picking a winner will fall to the competition's nine judges.
For impressionist Jon Culshaw and photographer Ed Robinson it will be their first time facing the challenge.
The competition winners will be announced at an awards ceremony on 17 September 2015, and will then be showcased at a free exhibition that will be on display at the Royal Observatory Greenwich.
