What an amazing world – looks essentially like a different place from different angles … Will there be daily pictures also on Saturday and Sunday? You surely have deserved a rest after the great event Wednesday. But then again … 😉
Hey!
Did someone bite a bit?
There is a strange shadow cast.
Oh I got it. the Sun is on the low right
Nice picture !
Given that there’s just one source of light out there and essentially no scattering (the coma is very tenuous), areas in shadows are very very dark indeed, which can be a bit disorienting 🙂
¡Es Condorito!
Es increible que hayan logrado todo esto, sigo el proyecto desde hace unos 6 años y me parece extraordinario la cantidad de energia y exactitud que le dedican, de verdad los felicito en este logro que sera un hito en la historia humana.
It looks more and more as consumed by chipping rather than just vapor. Hope a flake doesn’t detach and hit Rosetta
è FANTASTICO!!
Beautyfull, dark and mysterious—in time past a bringer of bad tidings
and today wonderfull science and studies,
thank´s rosetta !
Many of the images contain what seems larger layered structures and surprisingly straight edges. As if this thing is composed of two or more pieces of crust of a larger body that broke up into bits. Some of the images also seem to suggest these structures have curvature. Most notably the 3rd of August image. The image from the 7th at 96km shows a lot of curved structures as well. With curvature much larger than this comet. There is also a large difference in the number of craters between various sides of the comet. What could be the inner surface of a piece of crust has fewer craters than the outer surface.
Excellent image, the detail certainly looks like a science image rather than a navigation one.
That crater on the end, like the way ice bounders are becoming apparent as the resolution has increased.
Also the crater is terraced, something I would not expect on such a small object.
On large bodies like the Moon, Callisto, Mercury, Titan, Ganymede, Mars, Venus, Earth etc, yes, as there is plenty of surface gravity to cause slumping.
On a tiny object like Comet 67P/Churyumov-Gerasimenko , a huge surprise.
Terracing is not a problem if you realize most craters are formed electrically. It is a common misconception that impacts and gravity are the ONLY way of making craters. Experiments with high voltage discharge are far more successful than balls shot at sand pans. With 10kV and a lump of moist clay a perfect circular shape is cut with terracing and centre peak if you’re lucky – watch the video here: https://www.wikihow.com/Etch-Your-Own-Crater. All you have to remember is that everything in space is electrically charged, differences in voltage are maintained by plasma double layers. Close proximity of bodies can cause breakdown, which is accompanied by arcs and sparks on a prodigious scale – especially of they are planet-sized! Comets are just bits of broken planet, roasted and scarred as they separated in space a few thousand years ago.

Maybe a stupid question ,are these pic’s only in black and white, or has the comet no color?
It would be great to have an overlay of something we can relate to to get the size in perspective. Like a house, a town from above. It’s hard for me to have an idea how big this is.
This keeps getting better and better. Amazing. Thanks ESA and all involved on the Rosetta team.
