Beautiful pictures ... of what?
By Ransom Riggs
Thanks to Irene Müller for the kind use of her incredible photos!
Two substances meet and react; a laboratory-grade camera captures the results. Was the camera attached to the Hubble Space Telescope, trained on some distant nebula? Deep within CERN, perhaps, recording sub-atomic impacts at high-speed? Or on a simple tabletop? We'll give you a hint: the substances reacting are essential to mammalian life on Earth. Check out the photos and see if you can tell us -- what are they?
Answer after the jump!
