Our Favourite Space Images From 2013

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.

And projects like THINGS (The HI Nearby Galaxy Survey) have gone to great ends to catalogue the galaxies that have been observed thus far.

The Scale of the Universe is an informative Flash that shows the universe from the tiniest particles at fractions of a yoctometre (10-24 of a metre) to humans to giant nebulas that look like testicles to the very edge of what we can observe, many many gigaparsecs away.

The animation was created by a 14-year-old Cary Huang, with help from his twin brother Michael.
