Hi all,
An image of the unusual spiral galaxy Messier 94 has been uploaded. M94 has three distinct rings, the very bright inner one, the central one (with fine structure given by the dust lanes) and the outer one that looks like not having any structure, but this is only in the optical region. In images taken with UV filters of in the mid-IR region, this outer ring shows a complex structure with spiral arms. You can see the image as well as some more info at
Enjoy,
Josep
