Dawn Beams Back New Images of Ceres’ Mysterious ‘Pyramid-Shaped’ Mountain-
“No one expected a mountain on Ceres, especially one like Ahuna Mons. We still do not have a satisfactory model to explain how it formed,” said Dawn science team member Dr. Chris Russell, from the University of California, Los Angeles.

Re: Ceres!
I see two possibilities, based on the Mons being connected in some way to the crater.
The pair are very obviously parts of the same formation, to me.
A loop arc between two points of opposite polarity, excavates the material from the crater and deposits it to form the Mons.
We see these on the Sun. (The loops, not the craters and mountains they form - these are under the photosphere.)
Or (more likely), a positive and negative pair of currents touching down side by side. One evacuating material and one depositing material.

Re: Ceres!
Lack of a B field doesn't mean much.Ahhh didn't see the comment about Ceres lacking a mag field.
It still has an E field, with connected currents.
I'd define it as,How do you define "not that diffuse"?
not as diffuse as the inter stellar medium,
and way more more dense than the inter galactic medium.
But I bear in mind,
even more important than the density of the particles being pushed along, is the density of charge which is pushing them.

Electrically extruded mesa? And the crater next to it is not mentioned, but for EU it must be part of the formation process...Astronomers say they are still baffled by how the giant mountain formed on the surface
Some material or charge exchange?Pyramid' is in fact a dome with smooth, steep walls - one of which appears to glow

Re: Ceres!
On the side facing the crater.
Notice also, the Milky Way and stars are visible in the sky.
Can see the stars in many of these images. You don't get that with lunar shots.
What is the straight white line along near the top of the crater wall?
There is also another crater with bright areas, but on the walls in this one.
Kapalo Crater.
Did you see how bright the bright spots are in the first NASA animation?
Here, I captured it.
Seems exaggerated.
I let it auto play a couple more videos, and it came to a narrated animation. When it came to Ahuna Mons the NASA narrator says, "It isn't a crater, or even obviously associated with one".
I disagree.
It appears very obviously associated with the crater it meets exactly edge on,
and which at a glance, looks very near proportional in size to the Mons.

It's a shot from an animation. And the Milky Way is only visible because of Earths atmosphere, even from space.Notice also, the Milky Way and stars are visible in the sky.

Extremely.Seems exaggerated.

Re: Ceres!
Thank you for that link, GaryN.
Such an intriguing image, that I opened a new topic for it.
Is there really atmosphere at the altitude of the ISS?

Re: Ceres!
Thank you, Daniel.
I tried it (outlining it), but only two sides of the hexagon are accurate. The left and top left sides. Other sides are wrong angle and length.

There is experimental evidence to support your suggestions
On your third point, consider a facilitator, triggering interaction between two areas.
I'd go into more detail but the experiment which replicated the same results and my
suggest dynamics have been dismissed or shelved without explanation from t-bolts group.
To not add uncertainty to the discussion i cannot explain further
since clarity has not been provided in reciprocation to experiments.

Latest news about Ceres.
Organic material on Ceres
Ice on Ceres (including the discovery of hopping water molecules.) (??)

Organic material on Ceres
Ice on Ceres (including the discovery of hopping water molecules.) (??)
Ahuna Mons is an ice volcano (a cryovolcano)Regardless of its origin, water molecules on Ceres have the ability to hop around from warmer regions to the poles. A tenuous water atmosphere has been suggested by previous research, including the Herschel Space Observatory's observations of water vapor at Ceres in 2012-13. Water molecules that leave the surface would fall back onto Ceres, and could land in cold traps. With every hop there is a chance the molecule is lost to space, but a fraction of them ends up in the cold traps, where they accumulate.
Water molecule "hops" on Ceres.

Re: Ceres!
In short, Ceres is the only asteroid with an atmosphere, even if it's very very tenuous.

Ceres' Temporary Atmosphere Linked to Solar Activity
Studies suggest that the formation of a temporary Cerean Exosphere is dependent upon solar activity and not Ceres' distance from the Sun.
http://dawn.jpl.nasa.gov/news/news-detail.html?id=6802
Sublimation has been suggested but researchers conceded it was not able 'to produce the amount of exosphere that we're seeing'. Given that the study suggested that, during a six-day period in 2015, Ceres had accelerated electrons from the solar wind to very high energies, is this not yet further evidence of the electrical nature of all bodies in the solar system?
