Re: Comet Halleys Nucleus: An Orbiting Iceberg (2010 Jan 04)
In the photo there appears to be a spiral in the plume (easily visible if you tilt a laptop away from you). I understand the comet can spin but this looks more like it is rotating around some center of gravity. Is this just a camera effect or is something actually spiraling around in there?
