Planet Earth sits in the middle of the vast emptiness of space, according to the human eye. 

But a new discovery by European astronomers has confirmed that it is not so empty after all.    

Scientists at the University of Geneva's observatory say they have been using a newly invented camera that can spot galaxies born up to 10 billion years ago.

They say that previous searches for galaxies had missed up to 90 per cent of them.  

Al Jazeera spoke to Dr Francisco Diego, an astronomer from the University of London's observatory, about the new discoveries and how they could possibly revolutionise our understanding of the universe.
