Hello! And welcome to Astronomy Photographer of the Year online.

Before you go off exploring, we’d love it if you joined our Astronomy Photographer of the Year group on photo-sharing website Flickr. It’s a great place to see tons of amazing space pictures, pick up photography tips, and tell us your favourite image from this year’s competition.

And if you’d like to keep up to date with everything that’s going on at the Royal Observatory, Greenwich, including when entries to next year’s Astronomy Photographer of the Year open, then you can sign up to our newsletter too.
