Can the elecromagnetic spectrum be different in other solar systems? Do the different star types and numbers of planets andotation and positions might alter it

Question

Electromagnetic Spectrum Speculation

Answer 1

No.  The electromagnetic spectrum is the same.  What varies from one region of space to another is the range of the spectrum in which celestial bodies radiate.  But if they radiate at all, it is in some range of the same electrogmagnetic spectrum.
