I recommend take a look both winning videos and honorable mentions.
Of course the winner is awesome too:
Zebrafish embryo growing its elaborate sensory nervous system (visualized over 16 hours of development). Technique: Selective Plane Illumination Microscopy (SPIM). Dr. Elizabeth Haynes – Jiaye “Henry” He. University of Wisconsin – Madison
A multitude of discoveries are on the horizon after this much awaited release, which is based on 22 months of charting the sky. The new data includes positions, distance indicators and motions of more than one billion stars, along with high-precision measurements of asteroids within our Solar System and stars beyond our own Milky Way Galaxy.
See what happens at CERN during the Year-End Technical Stop (YETS – PDF), from 4 December 2017 until today when accelerator hibernation ends. Tomorrow hardware commissioning begins which will culminate in the restart of the LHC in early April (PDF).
String Theory Explained – What is The True Nature of Reality?
