Venus as I’ve never seen it before. From APOD. In this view Venus looks remarkably like Earth, which is expected given its very similar size and mass and presence within the habitable zone. LOL.

Venus at Night in Infrared from Akatsuki

Explanation: Why is Venus so different from Earth? To help find out, Japan launched the robotic Akatsuki spacecraft which entered orbit around Venus late in 2015 after an unplanned five-year adventure around the inner Solar System. Even though Akatsuki was past its original planned lifetime, the spacecraft and instruments were operating so well that much of its original mission was reinstated.

Also known as the Venus Climate Orbiter, Akatsuki’s instruments investigated unknowns about Earth’s sister planet, including whether volcanoes are still active, whether lightning occurs in the dense atmosphere, and why wind speeds greatly exceed the planet’s rotation speed.

In the featured image taken by Akatsuki’s IR2 camera, Venus’s night side shows a jagged-edged equatorial band of high dark clouds absorbing infrared light from hotter layers deeper in Venus’ atmosphere. The bright orange and black stripe on the upper right is a false digital artifact that covers part of the much brighter day side of Venus. Analyses of Akatsuki images and data has shown that Venus has equatorial jet similar to Earth’s jet stream.

Interesting that the possessive of Venus is written as both Venus’s and Venus’. To get a true match to the colours of Earth you need to take the negative.

Pleasing image. It does just look like someone has pasted a snap of a stormy Earth sky onto a “sphere” in Photoshop.

Inserted the negative of this image into Cartoon 503, see next thread.

If wonder if you could you “bleed off” Venus’s atmosphere over decades/centuries to make it more hospitable and if so would it return to the way it is over time

It’s the way it is because of outgasing from the interior. I’d need to know a bit more about volcanos on Venus to determine what percentage of the atmoshere could be replaced that way over a period of a billion years. Possibly zero percent.

I was wondering the following. If you swapped the atmospheres of Venus and Mars, would it cool down Venus and heat up Mars enough for both of them to become habitable?

Perhaps we could sequester it underground and use it for industry

Carbon dioxide + a bit of sulphur + heat. All you need to turn it into living things is a bit of nitrogen and a lot of hydrogen, and there’s a lot of that around.
