   Heat, thus defined, doesn't.  But energy can be converted from one   
   form to another.  Electromagnetic radiation and the kinetic energy of   
   particles that makeup "solar wind" and "cosmic wind" hit   
   concentrations of particles (eg. our atmosphere) and cause them to   
   vibrate.  Kind of like the cue ball hitting the pack in pool.
