The radio emission of the planet Jupiter was discovered in 1955. Over the past 66 years, more and more discoveries have been made, giving people a fascinating impression of how the signal works.
The spacecraft that has been orbiting Jupiter since 2016 has discovered a unique FM signal, presumably originating from the Earth’s Ganymede. Such detections have never been obtained from the largest and largest satellites in the solar system before.
According to NASA’s Jet Propulsion Laboratory’s website, the robotic explorer will now continue its mission to collect data on the largest planet in the solar system and its dozens of satellites, at least until September 2025 or when it ceases operation prior to.

The research will be extended to larger Jupiter systems, including Jupiter’s rings and large moons, which has attracted special attention because some of them are known to have water (especially Europa). In 201

The latter discovery places satellites in a short list of the most likely primitive locations in the solar system to find primitive life.
“Since the first detour in 2016, Juno has successively released a revelation about the internal operation of this huge natural gas giant. As the mission expands, we will answer the basic questions that arise during Juno’s main mission, while reaching beyond the earth. Explore Jupiter’s ring system and Galileo moons.” said Scott Bolton of the Southwest Research Institute.
“Milestone” signal sparks speculation
The radio radiation around Jupiter was first discovered in 1955 and has been extensively studied by researchers.
However, when Juno was flying at 50 kilometers per second (111,847 mph), he observed a milestone radio launch from Ganymede, one of Jupiter’s largest moons, lasting five seconds. These waves were detected on the lines of magnetic force connecting Ganymede to the giant’s poles. The research results were published in the scientific journal “Geophysical Research Letters”.
Although UFO hunters prefer to interpret the signal as being associated with some kind of extraterrestrial reality, this phenomenon is believed to be the result of electrons amplifying radio waves in the cyclotron lasing instability (CMI).
NASA spokesperson Katrick Wiggens quoted Utah as saying: “This is not ET, it is more natural.”
This phenomenon is related to physical processes. Although it is a relatively short process, it causes aurora to occur on the earth.
“The electrons thought to be spirals in Jupiter’s magnetic field are responsible for the radio noise we hear,” NASA elaborated.
The Juno spacecraft was launched to Jupiter in 2011. The mission is to explore how planets form and develop over time. The deadline for the mission is 2021.
The extended mission now includes 42 additional orbits of Jupiter, as well as the flybys of its moons Ganymede, Io, and Europa.
Juno plans to cross Ganymede’s low on June 7, 2021, and then head towards Europa.
The polar cyclones at Jupiter’s poles will be studied in detail. NASA hopes to conduct the first detailed study in history of the weak ring system surrounding the planet.
“The mission designer has done a great job in completing the extended mission, which can save the mission’s only most valuable airborne resource-fuel. Gravity assistance comes from the overflight of multiple satellites, guiding our spacecraft through the Jupiter system, while providing a wealth of Scientific opportunities,” said Ed Hirst, Juno project manager at the Jet Propulsion Laboratory (JPL).
