How about music?

FM near Jupiter

The Trump Train stops for a coffee / bathroom / smoke break (pick a pleasure). I ask The Committee about Frequency Modulation (as compared to amplitude modulation, or "AM" radio) signals discussed in the article. If you have not yet, I suggest reading it first.  

Q:      Just a short burst, was it really caused by the effect stated?
C:      No. Alien ET visitors to your solar system produced the signal.

Q:      Their purpose?
C:       Communication and data transfer

Q:       Any reason humans should be aware? Was the presence of our exploration craft the reason for the emission?
C:       No, the detection by the human Juno craft was incidental, accidental. Jupiter is frequently visited when passers-by and galactic tourists come to your solar system. As more human craft visit more planets, more such detections shall occur. 

Q:       What about the extraordinary chorus waves? Are these alien ET created, also?
C:        Yes, and are also evidence of their activity and presence. 

Q:         Galactic tourists?
C:         Of course, but with one significant difference. The visits are not vacations, not made to escape from something, to break routine or to rest. The tourists come to investigate, observe or see what has been studied and informed to them.

Q:         Isn't it complicated and expensive to visit Earth?
C:         Not to your visitor friends, no. 

Q:         Why?
C:          Such societies do not use money to measure value of resources or services, and the spaceships themselves do not deteriorate at nearly the pace humans would expect. No fuel is carried or consumed, no moving propulsion components are used and the spacecraft do not encounter air, water or other sources of friction, thus wear and stress. These craft can be used indefinitely. 

Q:         Can any member of an alien ET society come to our solar system to visit Jupiter?
C:         Yes, however this is varied by society. Earth is nearly always included in such visit, observation of humans is the main attraction. Waiting lists exist, the capacity of vessel creation or construction is the limit.
