"We've often seen the 'baby pictures' of planets forming, but until now, the 'teenage years' have been a missing link."
Dark matter doesn't emit light, it doesn't absorb light and it doesn't even block it, passing through ordinary matter like a ghost through walls (I’m very proud of that sentence.) Yet this invisible substance makes up roughly 85% of all matter in the universe, and its gravitational influence has shaped everything from galaxy clusters millions of light years across down to the rocky planet beneath our feet.
