Chandra X-ray Image of NGC 4258
NGC 4258 is a spiral galaxy about 25 million light years from Earth, also known as M106. The Chandra image of NGC 4258 reveals the so-called anomalous arms. These mysterious structures are due to shock waves generated by the supermassive black hole in the nucleus of the galaxy.

Spitzer Infrared Image of NGC 4258
The Spitzer Space Telescope infrared image of NGC 4258 traces the warm dust in the spiral arms, which follow the same structures that are seen in the optical data.

DSS Optical Image of NGC 4258
NGC 4258 (M106) is approximately 30 thousand light years across located about 25 million light years away. This image taken with the Digitized Sky Survey shows the "traditional" spiral arm structure in NGC 4258. These arms are offset by about 30 degrees from those seen in X-rays by Chandra.
