It's a real deal.

And we actually think that Venus was habitable in its early surface, our early life.

So even up to a billion years ago, we think that Venus was maybe habitable, had oceans.

And indeed, then at some point, that additional heat that comes from the greenhouse effect and from our sun caused all of the water to boil off and huge amounts of CO2 to be released from the surface.

And now we have this really hellish place to go that we can barely visit.

Yeah.

So Venus, like Earth, you know, has volcanism on it.

And we know this because of these surveys that have been done of Venus radio maps of the surface.

It's a very young surface.

So Mars is very old.

We see lots of cratering.

We think some of these craters, the amount of craters similar to our moon, it's maybe the surface is for over four billion years old, both the moon and Mars.

But Venus is different.

It seems like Venus underwent this catastrophic resurfacing maybe half a billion years ago, which means that volcanism is still active on the planet and it erased a lot of the craters.

And so how we are able to date solar system bodies is by kind of the number of craters.

You know, Earth doesn't have a lot of craters on the surface, right?

We have tectonics that erase that record.

And same with Venus.

Venus has a very young surface.

So it means volcanism is active.
