There are still many secrets hidden in the vastness of space. The BepiColombo space probe unexpectedly recorded a “singing” coming from the planet Mercury. You can find out what’s behind it here.
The basics in a nutshell
-
In one Stady Researchers from Japan and France, led by astronomer Mitsunori Ozaki of Kanazawa University, describe something astonishing: a galactic song from… Mercury.
-
Singing is called Choral waves. These are electromagnetic waves that sound like a chorus of birds at dawn.
-
Happy coincidence: the sounds were recorded by Mercury BabyColombo mission On a last trip.
Choral waves of mercury: further research planned
Choral waves are found not only on Mercury, but on other planets as well. They have already been found on Earth Jupiter And Saturn Beside Uranus Neptune was detected. The unusual thing: unlike Mercury, these planets have one Dense atmosphere And permanent Radiation belts on me. The radiation belt is the region surrounding the planets magnetic fieldwhere electrons, protons, and ionized atoms of heavier elements are placed.
This discovery raises new questions because Mercury, the planet closest to the sun, does not have a strong magnetic field. Due to its proximity to sun It is over and over again Solar wind Exposed to. The results of the study so far have shown that this has a clear effect on the shape of the planet’s weak magnetic field.
In addition, the choral waves were on Mercury Only in certain areas From the imagined planet. The data on which the study is based so far has been collected from flights about 200 kilometers apart in 2021 and 2022. BepiColombo’s entry into Mercury’s orbit is essential 2025 The decision. Scientists currently assume one Physical mechanism Which creates choral waves in certain areas. This phenomenon occurs especially when the solar wind has little influence (“dawn sector”). However, further observations and analyzes are needed to test the hypothesis.

The most frequently asked questions about Mercury
Mercury has been known since ancient times. Due to its fast orbital speed in our solar system, it is believed to be named after the Roman messenger of the gods, Mercurius. One of the wonderful features of Mercury is that it rotates three times on its axis during two revolutions around the sun.
Mercury’s diameter is 4,880 kilometers, and it is the smallest planet in the solar system, after Pluto, which is classified as a dwarf planet. Mercury is at least 75 million kilometers away from Earth, which is much farther than Venus and Mars.
Because of the extreme temperatures and lack of atmosphere, there is no way for humans, animals or plants to survive on Mercury.
