Many scientists suspect that extraterrestrial beings exist even ‘next-door’ to us: in our own Solar System. There are plenty of space objects out there besides Earth that also feature some characteristics that would make them able to host life. The presence of liquid water is, by far, the most important part.
Astronomers have long suspected that Ganymede has an entire ocean of liquid water. We’re talking about the largest moon in our Solar System, one that revolves around the largest planet: Jupiter. According to The Telegraph, a mysterious radio signal from Ganymede was intercepted by the Juno spacecraft that orbits Jupiter. Could this be a new reason to believe that there are aliens living on Jupiter’s moon?
The chances are low that aliens are the culprits
When Juno picked up the radio signal, the spacecraft was moving across a region of the gas giant where the magnetic field lines connect with Ganymede. The signal lasted for only 5 seconds, but it was enough to ignite the imagination of many. But Patrick Wiggins, who is a NASA Utah ambassador, comes to shatter our dreams:
It’s not E.T.,
It’s more of a natural function.
NASA explains Juno’s role:
Juno’s primary goal is to reveal the story of Jupiter’s formation and evolution. Using long-proven technologies on a spinning spacecraft placed in an elliptical polar orbit, Juno will observe Jupiter’s gravity and magnetic fields, atmospheric dynamics and composition, and evolution.
One of the best explanations for the radio signal is that electrons caused it. Electrons can amplify radio waves rapidly through the process of cyclotron maser instability, oscillating at a lower rate than they spin.
If advanced alien civilizations truly are there, somewhere in the Solar System, it’s only a matter of time until they’ll somehow wave at us. Let’s just hope that they have a friendly way of saying ‘Hello!’.
