Re-processed images of Venus

[ittiz]

Yes but the other image in this panorama only has 1/3rd color information.

Yikes!!! Sorry about the width folks!<br /><br />Ittiz. Even if the other half is only 1/3 colour more that 60% of the whole ponorama is still in colour. So my point stands.<br /><br />Jon <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em>  Arthur Clarke</p> </div>

The reason I'm saying this is because I have worked on colorizing those images. Although I have technically got them colorized to what it should look like lots of color detail is missing. Although this isn't noticable to the human eye.

 

[JonClarke]

The images were taken through filters so how is the data missing? Are you saying there were data dropouts?<br /><br />Jon <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em>  Arthur Clarke</p> </div>

Here is a link to the image of the actual data. You can see that it repeats about three times (the space craft sent it more than once incase there was a problem). But the color channel images are small for some reason. The data just doesn't seem to be there.

Here's the layering I found interesting. Refer back to Jon's image for the same photo without my scrawled lines. <div class="Discussion_UserSignature"> <div class="Discussion_UserSignature" align="center"><em><font color="#0000ff">- - - - - - - - - - - - - - - - - - - - - -</font></em> </div><div class="Discussion_UserSignature" align="center"><font color="#0000ff"><em>I really, really, really miss the "first unread post" function.</em></font> </div> </div>

Hi borman & Silylene,<br /><br />I see what you mean. The layering is very apparent. It is still layers of ash I'm afraid.<br /><br />Please borman & silylene, keep posting your observations on here, as it also helps me to 'see' more detail. <br /><br />Silylene, your illustration is not silly scribbles, it is a serious observation you made, you were good enough to have shared it & is most welcome. <br /><br />Thank you very much for posting it.<br /><br />Hi Jon, at the moment, I still think that Venus re-surfaces it self. Over the weekend, I literally poured over hundreds of Magellan images, to see, if there was just one, one piece of evidence to support subduction zones or linear volcanism. I could find none, so IMO, the volcanism on Venus, along with the Moon & Mars, was / is hotspot volcanism.<br /><br />I think the 'coronae' on Venus ,where were 'plates' tried to form over magmatic upwellings in the upper mantle doming the crust upwards (a few fissures had formed allowing for some smaller volcanoes to form, Boann Corona, worth checking out) & the strong surface gravity (89% of that of Earth).<br /><br />http://nssdc.gsfc.nasa.gov/imgcat/html/object_page/mgn_c130n135_1.html<br /><br />Small volcanoes on Boann Corona below, Magellan Orbiter Radar Image.

The colour images were collected at lower resolution, which is quite reasonable given the fairly monchrome nature of the surface.<br /><br />Jon <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em>  Arthur Clarke</p> </div>

Nice work! <img src="/images/icons/smile.gif" /><br /><br />Although I don't think the foliation is quite as well developed as you have interpreted, I think there is some there. I recall people claiming to have been layering in some other Venera images as well.<br /><br />Jon <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em>  Arthur Clarke</p> </div>

Hi there,<br /><br />I really do not see layering as being a surpise on Venus. Volcanic ash if blown & deposited in episodes will form layers, as does repeated volcanic eruptions of lava (provided the earlier flow solidifies first), it forms layers.<br /><br />Andrew Brown. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

Hi to you too <img src="/images/icons/smile.gif" /><br /><br />There are many ways of getting layering (sedimentary, pyroclastic, lava flow, tectonic foliation), we don't know which ones apply here. The high atmospheric pressure on Mars, equyiavlent to neary a km of ocean on earth, means that formation of volcanic ash is strongly inhibited.<br /><br />Jon <div class="Discussion_UserSignature"> <p><em>Whether we become a multi-planet species with unlimited horizons, or are forever confined to Earth will be decided in the twenty-first century amid the vast plains, rugged canyons and lofty mountains of Mars</em>  Arthur Clarke</p> </div>

JonClarke:<br />The high atmospheric pressure on Mars, equyiavlent to neary a km of ocean on earth,<br /><br />Me:<br />I suspect you meant Venus atmosphere.<br /><br />The most impressive of the images so far was one posted by 3488 of the near surface and distant horizon with plateu like hills. I don't even recall ever seeing that one in its original form. When I was in elementary school, it was hypothesized then that the atmospheric pressure was high enough to warp the view to the point the horizon would be bent kind of like looking from inside a fishbowl. Supposedly, you could also look straight ahead and see the back of your head ultimately. Do you or anyone else recall that bizarre theory? <div class="Discussion_UserSignature"> <p><strong>My borrowed quote for the time being:</strong></p><p><em>There are three kinds of people in life.

You right!

I'm on the old side of fifty and definetely senile, LOL. <div class="Discussion_UserSignature"> <p><strong>My borrowed quote for the time being:</strong></p><p><em>There are three kinds of people in life.
