An interesting fact that disappointingly I never get to use in normal conversation, is that if you put your phone in airplane mode and then placed it on Jupiter, it would be the brightest radio source in the Green Bank Telescope's field of view.

@MasterNinjaTS Do you mean "held it in front of Jupiter" ?? If you actually placed it on Jupiter it wouldn't be very bright from Green Bank would it?
@MasterNinjaTS Hmmm, but Jupiter itself is an incredibly powerful source of radio waves... Much more powerful than your phone!
@DrFunkySpoon I mean on Jupiter, as a testament to the dish's sensitivity to radio waves.
