Think back to when you were very young and someone first explained blindness to you.

“To me, science is beautiful and full of wonders. However, the beauty of science is often hidden inside research laboratories and buried in scientific literature. By creating engaging visuals and make them available to the general public, I believe more people would appreciate the beauty and wonder of science, and hopefully get interested in science.”

We think that Liang’s video – which features a handful of mesmerizing chemical reactions – does just that. Enjoy.

Until now, our perception of the dwarf planet has been shrouded mostly in mystery.

Yet there is one man aboard New Horizons without whom we wouldn’t be here at all.
