...the planet's surface... a smoldering 470° Celsius... shows signs of recent geological activity, with hot spots resembling those beneath Hawaii... appears to be insulated by one large, solid lid... Some regions in the southern hemisphere... are emitting more heat than others... appear to be younger... with basaltic lava flows... at least nine volcanic hot spots, or mantle plumes.. between 250,000 and 2.5 million years old... Though alternative explanations for the Venusian veneer point toward cataclysmic processes, Svedhem says the data support gradual resurfacing... a thin layer of ozone on Venus' nightside... only one-thousandth the amount on Earth... the presence of Earthlike lightning in the Venusian clouds remains disputed... the Japanese Akatsuki spacecraft... failed during orbit insertion... with a second attempted rendezvous planned for 2015... If Akatsuki does enter Venus orbit, it will begin imaging the Venusian clouds... At the... poles, that shroud's height shrinks to 65 kilometers... embellished by mysterious vortices... swirl around a central 2- to 3-kilometer-wide hole, a tunnel that plunges through the atmosphere. And they look like Earth's hurricanes, except that they are about the size of Europe, says Dmitry Titov of the European Space Agency and the Max Planck Institute for Solar System Research... the vortices appear to be the result of a global pattern of atmospheric circulation known as "superrotation." The clouds on Venus fly around the planet at speeds up to 150 meters per second, completing a round trip in just four Earth days, even though a single Venusian day lasts for 243 Earth days... While a number of plausible scenarios have been developed to describe Earth's atmospheric circulation, they all "fail completely" when applied to Venus, Svedhem says... Sometime in mid-2015, the spacecraft will fall into the toxic clouds.

An “extra, extra” ping to the APoD list members. One kinda boring picture.

That’s about 130 degrees Celsius below the temp of molten rock.
It might be boring, but it is also fascinating because it allows to know the Goldilock zone for sentient life.
Yeah, heh, and the lack of tectonic plates continues to puzzle researchers. ;’)
Interesting.
:’) I like to kid myself and think Earth falls in that zone. ;’)
Thanks, I edited out the global warming agitprop.
It does, but on some days I have to ask, WHY?
It was certainly smart of our astronauts to leave the US flag on Mars, not on Vernus—it would have burned up on Venus.
EXCERPT:
...Mariner II confirmed Velikovsky’s predictions: the surface temperature of Venus is at least 800 deg F; the planet’s atmosphere is heavy and 15 miles thick; it is composed not of carbon dioxide or water, but of heavy molecules of hydrocarbons. Harper’s editor Eric Larrabee wrote: ‘Velikovsky offers evidence from numerous other sciences, in particular geology and archaeology. Breaking the barriers between disciplines, he arrives at conclusions which no discipline had reached independently.’
The fact is this: the temperatures on Venus cannot be accounted for by a mere Greenhouse Effect, the temperature is just too extreme, and the surface gets far too little sunlight. The very scenario of a visually dense layer trapping in heat over a visually clear layer as it passes light to warm the surface is wrong. The scenario does not exist. One must remember, this is the very circumstantial evidence on which Global Warming was formulated - the very reason the alternate theory was disregarded was not because it was unscientific, but because it was formulated using ancient texts that are supposed to be myth.
lol.....
Back in the 1950s, as a teenager, I was on Mars with Bradbury (”The Martian Chronicles”), and on Venus with Heinlein (”Between Planets”). There was life (intelligent life) on both worlds then. Ah, those were the days.
Wish you hadn't done that. It would have been fun to view all the fossil fuel burners.
There’s another Hawai’i on Venus — woo hoo!
Now we can enjoy a tropical paraidse without all the goofy place names.
:’) That was the view of the late George Adamski as well. ;’) Asimov did a short story called (I think) “The Long Rain”, which has Venus a rain forest where the rain basically never stops, and there’s a Vietcong-like native insurgency opposed to Earthling dwellers, so they go around destroying the habitats (which are dry and brightly lit inside). And Burroughs had his first-person Mars stories, as well as at least one Venus novel.
