(CNN) Three bouncing oil droplets showing quantum physics in action. A clown fish peering out from the tentacles of a sea anemone affected by climate change. A cone-shaped cloud looming above a hill in the Yukon, Canada. Fish skirmishing in the wetlands of Hong Kong. A rare lunar phenomenon in Belarus.

These are some of the winning entries in the fifth Royal Society Publishing Photography Competition, which celebrates achievements in science photography

Dr. Aleks Labuda's "Quantum Droplets" was crowned the winner of the Royal Society Publishing Photography Competition.

In its fifth year, the competition "celebrates the power of photography in capturing scientific phenomena" and recognizes the role images can play in making science more accessible.

This year's first place image -- showing silicone oil droplets bouncing continuously above a petri dish of vibrating oil-- was taken by the physicist Dr. Aleks Labuda and demonstrates a theory called pilot wave theory.

Morgan Bennett-Smith's "Fade to White" shows a clown fish among the tentacles of a bleaching sea anemone in Thuwal, Saudia Arabia.

The French physicist Louis de Broglie first came up with this theory in 1927, suggesting that quantum particles are simultaneously particles and waves.
