In the first of those 2 images there seems to be a channel on the surface, running from about the 4 o'clock position of the 'lit' crater down to another less bright but still obvious feature at the bottom right of the image. Nice big well defined hex crater showing too.

I admit, these spots are weird. It is hard to get an idea truly how bright these spots are. Does the scattering suggest crystal formations? Artificial? Electrical or just a high albedo surface material.

It's a giant concretion.

Just like the geodesic dome crater on mars.

Since 1 % 1, 1 * 1 and 1 - 1 do not add up, we must conclude that 1 + 1 is 3.

I can't seem to find any info on why the NASA scientists can conclude that the bright spots are due to a reflection. I understand that they disappear when Ceres rotates out from the sun's light, but could it be rotating out of the sun's electrical influence? Also, the brightness doesn't seem to change, meaning the hypothetical reflective surface must be uniform. Why would there be a change in a tiny fraction of the surface in the center of a crater? It cannot be ice... perhaps a salt deposit?

An electrical interpretation would also explain the plumes of water/hydroxyl on Ceres... something a reflective surface does not do alone. I think we're observing the process which forms the bulls-eye pattern found everywhere on Ceres and other planetary bodies, proving that they are not caused by impacts as always assumed.

Yes, that is possible. An EDM crater would be caused by the interaction with the solar wind. This must be a slow process. When the discharge fades it is likely that a new spot on the surface will appear, this can be a new crater next to it, creating a crater chain, or maybe a smaller discharge on the rim.

Hi Eric,

Yes it would, simple reflection does not have such a high albedo. If it is EDM caused by the solar wind then where ions and electrons recombine light is produced.

Daniel


ps. Not EU links, but very high albedo is not really as simple as saying ''it is ice:http://milesmathis.com/encel.pdf and http://milesmathis.com/encel2.pdf /

Crater chains now observable.

So which process is responsible? For Mars we have:
Hypotheses regarding the formation of pit crater chains require development of a substantial subsurface void to accommodate collapse of the overlying material. Suggested mechanisms of formation include: collapsed lava tubes, dike swarms, collapsed magma chamber, substrate dissolution (analogous to terrestrial karst), fissuring beneath loose material, and dilational faulting.

LOL, This reminds of the scene in Monty Python the Quest for the Holy Grail where the village idiots identify a witch by balancing her on scales with a duck. Hilarious these scientists.

Published on 27 May 2015
In April of 2015, the NASA Dawn Spacecraft began transmitting new, close-up images of the mysterious dwarf planet Ceres. The images to date have only deepened the mystery surrounding the puzzling bright spots on the planet’s surface. However, in addition to this ongoing puzzle, questions remain about Ceres that planetary scientists seem unready to ask. The surface of Ceres is massively cratered, with a variety of types of craters, including so-called bulls-eye craters (craters with central craters), craters with central peaks, and weird hexagonal craters, such as those seen on Mars, Mercury, and the Saturnian moon Mimas. Dawn’s exploration of Ceres is a startling reminder of just how inadequately the modern theory of planetary cratering explains what we actually see on planets and moons

---

And of course crater chains, the new close up reveals small crater chains and in earlier pictures you could see large crater chains at the north pole (large/small refer to crater size)

Daniel

Meanwhile the hexagonal clouds of Saturn's poles fail to ring any bells. "Hmmm, I've seen that shape somewhere else nearby..."

No big deal I know, but these look like some nice crater chains on Ceres:

I'd say the close-ups should be pretty good!

Un-freaking-believable! The article still calls 67P an "icy body."

The dogma did not bark in the night, that is the curious thing.
Actually, the curious thing is what this is doing in the Ceres thread...
