1. An astronomical challenge
For Stargazing Live 2015, you helped us create one of the most detailed wide field space photos ever taken.
By combining your photos of Orion – taken using just standard digital cameras – we created a stunning composite image revealing the incredible details of stars and nebulae across the constellation.
This helped astronomers pioneer a new way of studying the night sky without the need for professional telescopes.
