Temperature gauges all over my ship for no apparent reason?

[noxgandhi]

I have an ongoing mission which is supposed to check Minmus for ore. It is pretty far away from any atmosphere but when i decided to check on it today (I don't really warp..) i came to see this:

My question is simple: what is going on with my ship? Is this a bug or does it have to do with the latest update - maybe some radiation heating or something.. ?

Thanks

You ran a nuclear engine, and it dumped its heat into the ship as the vessel reached thermal equilibrium. Some wing parts would help it radiate away faster, but it's not worrisome unless you need to run the engine more.

You can turn off the heat gauges by pressing F10.

Solar panels will also radiate heat.

Also, those temp gauges have memory leaks and will crash your game in 1.02. You must disable them with F10.

Thanks guys. I guess the temperature of parts doesn't drop if the respective ship is not active/selected. Anyway.. didn't expect KSP to become this realistic regarding thermodynamics

Lil' follow-up for those interested.. everything went well. Probe is now in polar Minmus orbit and performs surveys for the mining ship coming in tomorrow:

Thanks again for calming my butt
