The Hubble telescope has been showing us breathtaking images of space since its launch in 1990. So far it has made 1.4 million observations. Physicist Dr Casey Handmer took 936,000 of these observations and created an insanely detailed composite image of all of them.
After piecing the composite together (using calculations and coding rather than Photoshop!) Dr Handmer realised that around 0.8 per cent of the sky was on show.
