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.)

    $\begingroup$ Please link to this news item. This question is a question about the operation of an artificial satellite, and so is off topic here. But it may be on topic at Space Exploration. But you will need the link to the news item to be in place. $\endgroup$

  • $\begingroup$ 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? $\endgroup$
