The Curious Glowing Rocks of Comet Chury

The ESA released a new image of the comet 67P/Churyumov-Gerasimenko (Chury for short) today, and this one seems to have another curious oddity.

In the original image, we can see faint “jets” seeming to erupt from the middle of the comet:


When the image is contrast enhanced, the source of the jets seems to be coming from the rocky surface itself, rather than from a well defined “vent” source.


The contrast enhanced image seems to show a curious phenomena… the rocks are glowing.

Taking a zoomed in portion of the image and setting it to an animation of contrast, we can see a glowing halo emerge from the boulder in the center of frame.

This is not an artifact.  The boulder in the image is surrounded by a faint glow.  As you can see from the above image, this glow does not appear on other rocks that are contrast enhanced.  It only appears on the rocks that seem to be the source of the “jets.”  Of course, these aren’t really “jets” at all, they are an electrified plasma discharge into silicate rocks.

Here’s an animation taken only from NavCam image C that was used to make the large full sized image of the comet.  The glow is still there, because the area surrounding the boulder is the source of the jet.  The jet is not coming from a distinct crack in the rock, which is something I also predicted:

7. No “water” jets or vents will be pinpointed, but OH blooms will be identified to be coming from the ridges of craters and from areas of whiteout on the image sensors.

We can look at the surrounding rocks and see they are not glowing. They have sharply defined edges no matter what the contrast and brightness settings are adjusted to. This is not true for the area around the boulder that fuzzes up because of the discharge that’s surrounding it.

Just to be clear, it is impossible for a neutral gas to behave this way.  The only way to explain “jets” in the standard model of comets is to assume the “jet” is expelled sublimating water vapor from a crack in the rock under pressure.  That is not what we observe here.

In a previous article, I commented on the presence of an anomalous glowing disk that appeared in a recent image of Chury that some people had claimed was a UFO.  In that article I demonstrated the glowing disk was most likely a plasma discharge.  As the comet gets ever closer to the Sun, we will begin to see brighter and more numerous discharges blasting away the comet’s surface.

The red dot is the location of the “UFO” in relation to the contrast enhanced “jets”:


There is no ice on comet Chury.  There are no jets of sublimating water on comet Chury.  There is no ice hidden beneath the surface of comet Chury.  The processes taking place on the comet are entirely electrically driven.
