On the local TV news, it was alleged that x-rays from some satellite could interfere with something on earth. I didn't hear it but my wife thought they were talking about WiFi or internet or something like that. (She's had people jobs, so technical details aren't her expertise.)

I know that more than one satellite is detecting x-rays. Are there actually any emitting them? If so, what could it interfere with? (Perhaps the latter question belongs on Physics.)

  • $\begingroup$ X-rays can’t penetrate the Earth’s atmosphere, so the scenario as stated isn’t possible. (And I don’t see how even locally generated X-rays could interfere with WiFi.) $\endgroup$ Commented Jan 10, 2022 at 11:04
  • $\begingroup$ Me neither. But I am still skeptical about whether a satellite emitting x-rays even exists. $\endgroup$

  • $\begingroup$ There is some interest in looking at X-ray communications with deep space spacecraft, but in this case the transmissions would be pointed away from Earth and towards some distant spacecraft. See Space Exploration SE questions tagged x-ray-communication especially What will the X-ray communications (XCOM) transmitter look like? $\endgroup$
