Space weather. For Earth to loss heat space must not be total vacuum. Wonder if Space Station measures changes in how cold area close to Earth varies, and wonder how much tempetures changes in star stuff called solar winds.

Actaully there is no channel but at this time NASA and other space agengies around the world do keep an eye on "space weather" because our environment is greatly affected by different things from space such as solar storms.

Earth loses heat to space by radiation, the same mechanism by which the sun heats the Earth. This works in total vacuum. Space itself has no temperature to measure. The effective radiation temperature of space is about 5K (5 Celsius degrees above absolute zero) and represents the combined effect of the microwave background and all the stars and galaxies.
While the particles in the solar wind can be very energetic (i.e. hot), the density of the wind is so low that its thermal influence is negligible. Its biggest impact on us is the electric currents it produces when it hits Earth's magnetic field, or a satellite.
