Doesn't this depend very much on exactly how terraforming was being done and at what stage it was currently at? I think this question is way too broad and opinion-based to be a good Astronomy SE question. It's possibly suited to [World Building SE](https://worldbuilding.stackexchange.com/) but even there, you might need to add some more details or be ready to respond to comments *asking for* details.

I’m voting to close this question because it requires too much speculation not based in science - especially not based in Astronomy (so off-topic) and lacks any specifics. There isn't a single, generic "terraforming work flow" or SOP we can work from.

This question _might_ be appropriate for Space SE as [they do discuss terraforming](https://space.stackexchange.com/questions/tagged/terraforming), albeit usually from the perspective of how we could do it.

Relevant to planetary atmospheres, spectroscopy, recurring observational programs.

Perhaps Venus was “terraformed” by aliens who prefer such an atmosphere. Ok, unlikely, but why think aliens would prefer what we do?

@JonCuster I never said they preferred what we prefer.

How could we detect if Venus or mars were being terraformed by aliens?

(Asked by: username_0 on 2022-11-28)

If any other body in our solar system was being terraformed by aliens, what would be the ways in which we would detect this?

Initially I thought of Venus or mars but I guess this could extend to any body within the solar system.

What would be the first signs? Who would be the people that would actually start detecting changes?
