NASA has extended the duration of its Juno mission recently and it seems that it has been worth it. The Juno spacecraft has traced an FM radio signal transmitting from the moon of Jupiter Ganymede. For the first time, scientists have been able to find something from this moon of Jupiter. Patrick Wiggins, who is one of NASA’s Ambassadors to Utah, has said that it is a natural function. The Juno spacecraft has been orbiting across the polar region of Jupiter, where magnetic field lines join to the moon Ganymede while it crosses the radio source. Scientifically, it is known as a decametric radio emission. On planet Earth, it is known as Wi-Fi, which we use here. Some scientists have said that for the first time the radio signals from Jupiter have been identified in 1955. They have said that over the last 66 years, more findings have been made about how these signals work.
Patrick Wiggins has informed that a member of the Salt Lake Astronomical Society has been able to build an amateur radio telescope that can identify the electromagnetic radiation from Jupiter. The Jupiter space mission aims to study how the planet Jupiter has been formed and how it has been evolved over time. The scientists on board the Juno spacecraft has been analyzing the gravity of Jupiter, its magnetic fields, atmospheric dynamics and composition, and evolution, said the experts from NASA. Experts have said that electrons have caused the radio emissions from the moon of Jupiter, not aliens.
The Juno Spacecraft has found that the electrons move back and forth at a lower rate than they spin. It causes the electrons to intensify radio waves quite fast. This process is known as cyclotron maser instability (CMI). These electrons, which produce the radio signal, can lead to aurora as well in the distant ultraviolet spectrum. The Juno spacecraft has observed this phenomenon as well. The Juno spacecraft has witnessed the radio signal transmitting from the moon of Jupiter only for five seconds. Scientists have claimed that it has been traveling at 50 km per hour speed.
