Space is big. Really big. It would take a gargantuan trek of 21.24 billion kilometres for you to reach the outer edges of our solar system, and a further 435 sextillion (that’s 10 to the power of 21!) kilometres to reach the furthest region of the observable universe. There is so much to explore but what we’ve seen so far has been incredibly beautiful.
NASA’s Jet Propulsion Laboratory keeps an extensive catalogue of cosmic images taken by the various spacecraft up in the heavens. Here’s a small selection of our favourites space images taken in 2013.
