Definition: Newton's laws of motion (Sir I. Newton):
* Newton's first law of motion: A body continues in its state of constant velocity (which may be zero) unless it is acted upon by an external force.
* Newton's second law of motion: For an unbalanced force acting on a body, the acceleration produced is proportional to the force impressed; the constant of proportionality is the inertial mass of the body.
* Newton's third law of motion: In a system where no external forces are present, every action force is always opposed by an equal and opposite reaction
As far as I'm aware, NASA state that it's down to the movement of the camera. But I guess it's not, as they're all going in different directions at different times. (also at points when the camera is not moving)

what reasons does nasa give for these ice crystals moving like they do?
