Van Gogh's brushstrokes in 'The Starry Night' create an illusion of sky movement so convincing it led researchers to wonder how closely it aligns with the physics of real skies. Marine sciences and fluid dynamics specialists analyzed the painting to uncover what they call the hidden turbulence in the artwork. They used brushstrokes to examine the shape, energy, and scaling of atmospheric characteristics of the otherwise invisible atmosphere and used the relative brightness of the varying paint colors as a stand-in for the kinetic energy of physical movement.
