Is it true that the vacuum of space is a good thermal insulator?
Unclear. Two sources partially support the idea: one notes that evacuated vacuum insulation panels achieve very low thermal conductivity, and another notes that quasi-vacuum nano-spaces suppress heat conduction. Neither directly addresses the general claim that the vacuum of space itself is a good thermal insulator.
