M106: New GALEX image

July 24, 2008

[M106 in UV, GALEX]

The conspicuous spiral galaxy M106 was imaged with an UV telescope on Nasa’s GALEX satellite. This image is a two-color composite, where far-ultraviolet light is blue, and near-ultraviolet light is red.

M106: Anomalous Arms

April 11, 2007


Anomalous Arms show up in this multi-wavelength false-color composite image of M106 (NGC 4258).
In addition to the two well-known arms visible in visible and UV light, radio and x-ray images show two more, invisible (or visually very faint) spiral arms. Investigation with XMM-Newton, Chandra X-ray Observatory, and Spitzer Space Telescope have confirmed now that these arms are composed of gas heated by shock waves.
