 The appearance of a galaxy can depend strongly on the color of the light with which it is viewed. This galaxy, when seen in visible light, exhibits tightly wound spiral arms that give it a pinwheel shape similar to that of many other spirals. However, when the galaxy is viewed in ultraviolet light, its shape is startlingly different. Ultraviolet light has a shorter wavelength than ordinary visible light and is emitted from stars that are much hotter than the sun. At ultraviolet wavelengths, which are rendered as blue in his Hubble image, we see a spectacular, nearly circular, bright ring surrounding its nucleus. The ring marks the presence of many recently formed, hot stars.
