Would a nuke being activated in space stop it being detected?

Absolutely not. If you want to get all physicsy about it the scintillation effects in the ionosphere alone would cause issues with radio comms systems over a very wide area. You would almost certainly also detect the high energy E1 part of the pulse caused by gamma radiation ionising molecules in the upper atmosphere and the resulting EM wave.
We can detect the faintest echoes of the end of a stars life when they explode in a supernova thousands of light years away so it’s pretty clear that detecting a nuclear detonation relatively close to the Earth is very easy.

If it is a nuke in space its how you create a powerful EMP weapon. You know the stuff of bond movie baddies.
Seriously fucks up any electronics which isn’t shielded and radiation hardened.

I'm pretty sure that is the actual plot of Goldeneye

Well to be fair it’s loosely based on real science. Can’t remember which Mig aircraft it was that still used thermionic valves when the US got their hands on it, only to realise that after a nuclear strike the transistors and ICs in their aircraft would be significantly damaged where as the old style valves were immune.
Thankfully these days the hardened chips have a layer of depleted boron which provides shielding and are often Silicon on Sapphire rather than normal semiconductors.

They can calculate the age of stars billions of miles away in different galaxies, I don't think they'd have too much trouble detecting a nuke going off in space.

Well if life is imitating art then somebody needs to find out if Sean Bean has had any trips to Saint Petersburg recently.

They heared Armstrong fart on the moon, so reckon they would know :)

I think it's fair to say you'd notice.

The Russians also did similar.

What happens if what ever they have sent into orbit becomes damaged and it results in a crash landing into earth? Would this result in an unintended nuclear detonation where it lands?

The accident involving 2 USA planes in 1966 released 4 hydrogen bombs.
1 into the sea the others into a fishing village near Vera in Almeria, Spain.
No nuclear explosion, just massive radioactive contamination partly cleaned up but still contaminating a substantial agricultural area of Palomaris today.

Let’s hope it’s the swamp
