The earth heats up from the sun through the vacuum of space does it not. It is called radiation. The key is light travels through a vacuum.

Radiation is the only one of the 3 forms of heat transfer that will travel through vacuum...as the heat from the sun.
There is a rather large ÎT between us and the sun !!!

Well, yes heat can travel through vacccum in the form of radiation....to be specific infrared radiation.
We get sun's heat in the form of infrared radiation. It travels through vaccum --- a distance of about 15 million Kilometres

Yes, by radiation. That is how the earth gets most of its energy from the sun.
