surface image of Venus[edit]

I know the current image shows Venus as it actually looks like, but it is blurry and is low quality. The previous one, although possibly misleading, was much better looking. I would change it back Tetra quark (talk) 14:31, 25 January 2015 (UTC)

I wondered why these images weren't included: surface of venus (taken by the Russian Venera-13 probe in 1982). I also couldn't find those on wikimedia commons. Why is that? If they really aren't up there I guess someone should contact the copyright-holder or something. --Fixuture (talk) 15:39, 29 March 2015 (UTC)
It could have something to do with the copyright status of those images. I hope not, the article is not complete without an image like that. --JorisvS (talk) 17:18, 29 March 2015 (UTC)
If that's the case I guess we / someone should contact the copyright holder... --Fixuture (talk) 18:29, 29 March 2015 (UTC)
It does have to do with the copyright status. Essentially, all Venus surface images are owned by Roscosmos and can only be used under a fair use rationale (which is why they can't be hosted on Commons). Following deletion of the best image (which was the same one suggested here) from Commons ([1]), I added the current image as non-free content ([2]), choosing it specifically to be entirely uncontroversial with regard to fair use.
If you want to try to substitute a better image under fair use, I would recommend first talking to someone knowledgable on the subject like User:Huntster. A2soup (talk) 19:55, 30 March 2015 (UTC)
Alright, thanks. But do you know if someone already contacted Roscosmos about whether or not they'd be willing to "open source" / change the copyright-status of these images? --Fixuture (talk) 20:08, 30 March 2015 (UTC)
I'm not knowledgeable or bold enough to enter negotiations with the Russian government on the issue, but feel free to try yourself. I (and another user) recently tried something similar with ESA about a Mars image and got an apologetic negative response (see discussion here).
I may come through later, though, and change the current image to a reduced-resolution version of the image you proposed. It would be a bit more controversial, but still allowable (I think). The whole fair use thing is very fuzzy. A2soup (talk) 21:15, 30 March 2015 (UTC)
I doubt anyone has contacted Roscosmos about this specific issue, but they do not release images under a free license as a policy. I've never known of an exemption to that. Also, if folks don't like the current infobox image, why not move File:Venuspioneeruv.jpg into its place? It looks significantly better to me. Huntster (t @ c) 00:40, 31 March 2015 (UTC)
It's not the infobox image, but an image by a lander. The only currently included image [3] is just ridiculous, it does not tell the reader half of what is possible. Can't we use one decent image under fair use? --JorisvS (talk) 08:03, 31 March 2015 (UTC)
Yes, I was primarily replying about the surface image, but I thought someone had asked about the global image as well, which is why I mentioned it. I must have misread something. Regarding the surface image, it doesn't matter which image is used or from what mission. If you have a preference, lay it out. Huntster (t @ c) 15:07, 31 March 2015 (UTC)
True, this thread seems to have originally started about the infobox image, but then quickly went on about an image from the surface. No one seeks to change the current infobox picture, AFAIK. I probably like almost any image from the surface better than the current one, including the one linked above (in the first response). --JorisvS (talk) 20:40, 31 March 2015 (UTC)

Formation of Venus[edit]

There is a lot of information on Venus but no subtitle which outlines how this object formed. As well, how exactly would an object, so called Earth's twin, have such different features such as no strong global magnetic field, active plate tectonics, water oceans or life? Seems to me we are studying an object which is NOT Earth's twin.Wavyinfinity (talk) 18:14, 19 March 2015 (UTC)

In culture - Change this title to - In culture and religious thought[edit]

Add the following second paragraph to this section (paragraph will sit right above the Etymology section).

A book published by Christian thinkers in 2014 titled Venus: Don't Go There - What Science and Religion Reveal about Life after Death presents the planet Venus as an appropriate biblical model for where condemned souls go after the Day of Judgment. The text argues that heaven, hell, and the lake of fire exist in material form within space and time and are not just abstract ideas. </ref> BlueInk Book Review Services </ref> — Preceding unsigned comment added by Michaeltsantini (talkcontribs) 21:10, 23 March 2015 (UTC)

Doesn't seem very notable, and anyway, the Bible depicts Hell as a lake of burning sulphur, and as everyone knows, suphur boils at 445 C, meaning that Venus is actually hotter than Hell. Serendipodous 08:46, 31 March 2015 (UTC)

Retrograde rotation versus animation[edit]

The animation in the article shows Venus rotating counter-clockwise together with other planets but the text speaks about retrograde rotation. Pavlix (talk) 12:55, 20 April 2015 (UTC)

It doesn't show Venus rotating counter-clockwise: it shows Venus revolving counter-clockwise. The terms are confusing, but unfortunately pretty standard. Double sharp (talk) 09:47, 21 April 2015 (UTC)

surface geology / volcanoes[edit]

"Much of the Venusian surface appears to have been shaped by volcanic activity. Venus has several times as many volcanoes as Earth, and it possesses 167 large volcanoes that are over 100 km across. The only volcanic complex of this size on Earth is the Big Island of Hawaii."

What about Kerguelen and Iceland, or do they not count because they're not single volcanoes? 93.103.55.68 (talk) 00:39, 26 April 2015 (UTC)

Here is the reference for the statement. If there are other sites to be added, we'll need suitable references. Praemonitus (talk) 17:53, 24 June 2015 (UTC)
