I have a problem with the images returned by the EPOXI mission fly-by of Hartley 2.
In the images, it appears to me that the so-called "dust jets" emanating from comet Hartley 2 are luminous.
As the comet rotates, the jets exhibit clear luminosity in the dark side of the comet. They are far far too bright to be simple dust jets.
Does anyone else find the apparent luminosity of the jets in the dark side of the comet odd?
There are several pictures where the jet is clearly in the shadows yet it glows like a plasma discharge.
In the close ups you can see fine collimated jets emanating from bright point sources in the dark side of the comet.
