USS Juno

The universe is like a boundless space, and mankind's exploration of it will be never-ending. Whether it is a manned spacecraft, a probe, or a radio telescope, researchers are using a variety of technologies to unveil the mysteries of the universe.

Jupiter, one of the eight planets in our solar system, is by far the largest planet in our solar system, and so far, humans have discovered 79 moons orbiting Jupiter. Not long ago, the Jupiter probe picked up radio signals from Jupiter and scientists have roughly pinpointed its location.

Jupiter's exploration

In the late 1970s, NASA launched Voyager on a mission to explore Jupiter, during which Voyager sent back to Earth thousands of photographs, both of Jupiter itself and its moons.

These photos provided some insight into Jupiter's surroundings and even revealed traces of volcanic eruptions on Jupiter's moons.

In addition, Voyager's flight confirmed the existence of Jupiter's lightning, but the radio signals were different from those on Earth. Now, forty years later, the mystery of Jupiter's lightning has finally had a chance to be uncovered.

Juno's flight

Juno is also a relatively famous Jupiter probe, although compared to Voyager Galileo is slightly inferior, but can not deny his contribution to the exploration of the universe. The name "Juno" is derived from Roman mythology, with the symbolic meaning of clearing the clouds and expressing people's high hopes for Juno, hoping that it can answer more questions about Jupiter.

During its flight, Juno, like other probes, will persistently send signals back to the ground. The distance between Earth and Jupiter is very long, so the signals are sometimes very weak, and it is a challenging task for researchers to capture the relevant signals accurately and in time.

Juno has been affected by the flight, and after research, it was found that the force of the magnetic field on Jupiter may have affected it.

Jupiter has a strong magnetic field force, ranking first among the large planets in our solar system, with Earth less than one-tenth of its magnitude. Juno carried a wealth of scientific instruments on its expedition, and mapping Jupiter's magnetic field was one of its missions.

Radio signals

When the Juno mission received the sound source of radio signals from Jupiter's magnetic field, it was a hard-won surprise for astronomers on Earth, who could only use the data to try to understand the signals from the outer planet while having a chance to pinpoint their location.

Only through the accuracy of Juno's positioning will scientists have a chance to understand the general picture of Jupiter's magnetic field and how it changes as Jupiter changes. As mentioned above, Jupiter's magnetic field is so powerful that it must then cause other planets to change.

It is the moon closest to Jupiter and is in its magnetic field. The moons adjacent to Io can easily create a tug-of-war with it.

Such tearing and friction release heat from its interior, and the magnetic forces it releases can even affect other planets. When these moons act together, they naturally create a powerful force, the end effect of which will affect the eruption of the volcano, providing sufficient energy and power for the eruption.

Radio signal generation source

The erupting volcanoes "drop" more than 1t of particles and gases into the space around Jupiter. Notably, some of this material splits into charged ions and electrons, which are eventually attracted to Jupiter's magnetic field and move rapidly.

In the process, these charged materials will generate radio waves, and thus there is a chance that the instruments carried by Juno will capture them.

Scientists believe that although Jupiter's lightning and Earth's lightning differ in detail, they do not differ much in form. Wherever it is, lightning is like a kind of radio transmitter, emitting powerful radio at the moment it cuts through the sky.

Scientists use Juno's detection data for analysis to initiate the tracking and location of such radio waves. Such radio waves act like a cone as they propagate, but are hollow.

The researchers said that the captured data can be analyzed to the precise location of radio emissions in Jupiter's magnetic field, and these locations can produce radio waves cause. It is because the density of electrons here is not more or less, while the magnetic field strength is also more appropriate.

Scientists found that the electronic energy of radio signals generated on Jupiter is more than 20 times higher than its predicted value.

The signal is not easy to come by

If Juno wants to pick up the right radio signals, it needs to be in a suitable position, and if the position is off, it may pass by the signal.

These signals are like lighthouses on the sea, constantly sweeping in the darkness, the lighthouses give guidance to people sailing on the sea, and the radio signals are for the Juno to guide, if there is no correspondence, it is difficult to be found.

So in the vast universe, the signals and information obtained by the probe are not easy, and whenever a surprise appears, it is undoubtedly the best consolation for the scientists on the ground.

By summarizing and analyzing these ever-changing data, scientists can apply them to the study of the Earth, because there are also countless planets around the Earth, and, inevitably, they will not cause any kind of results.

The data from detections and studies may only be used as a reference, but they can at some point play a predictive role, allowing us to prevent problems before they occur.

With the continuous development of science and technology, people have the opportunity to explore discoveries and enrich their knowledge of the outside world. It is with the renewal of technology so that new technologies are applied to the universe, that Juno has the opportunity to carry out a more comprehensive exploration of Jupiter's lightning and gather more comprehensive data.

The exploration of the universe is desirable, and discoveries will always attract a lot of attention, whether it is the signal from Jupiter, or the pictures from Mars, all waiting for scientists to discover and dig step by step.
