This composite image made available by NASA shows the galaxy NGC 4258, also known as M106, about 23 million light-years away from Earth. Two extra spiral arms glow in X-ray, optical, and radio light. These anomalous arms are not aligned with the plane of the galaxy. The data was captured by the NASA's Chandra X-ray Observatory, the National Science Foundation's Karl Jansky Very Large Array, the Hubble Space Telescope and the Spitzer Space Telescope.
