Saturn's hexagon change in season. These changes were observed by the Cassini spacecraft. One hypothesis, developed at Oxford University, is that the hexagon forms where there is a steep latitudinal gradient in the speed of the atmospheric winds in Saturn's atmosphere. Similar regular shapes were created in the laboratory when a circular tank of liquid was rotated at different speeds at its centre and periphery. The most common shape was six sided, but shapes with three to eight sides were also produced. The shapes form in an area of turbulent flow between the two different rotating fluid bodies with dissimilar speeds. A
A Road at Saint-Remy with Female Figure A Road at Saint-Remy with Female Figure Vincent van Gogh painted A Road at Saint-Remy with Female Figure while staying in Saint-Remy in 1889. The distinctive painting style of Van Gogh's later works is very apparent in this painting as the road, vegetation and sky is all rendered with his thick characteristic brush strokes. The painting depicts a woman walking towards a house at the end of a small road at Saint-Remy in France. The sides of the road is covered in green and yellow vegetation as fall has set in, and the fall also seems to have brought its
