I’m not sure how this is new information. If heat didn’t radiate out through a vacuum then Apollo 13 would not have been cold soaked after turning off the heater, heck they wouldn’t even need one. Another question is how did they keep the astronauts from getting cooked by the sun or freezing when not in sunlight?

 

so many questions...

 

I understand space isn’t a perfect vacuum but it’s sure as hell empty enough that normal modes of heat radiation won’t work. 
 

maybe I should have paid more attention in Physics classes. 

This is a different effect entirely. Spacecraft have, obviously, always relied on infrared radiation to lose excess heat. The article talks about the discovery of heat transfer between two objects separated by a vacuum exceeding the amount of IR radiation. This effect works only on the nanometre scale, so it has no relevance for spacecraft.
