NASA’s Voyager-1 hears interference from interstellar plasma outside the solar system.

There is no wind in the interstellar region outside of our solar system, but beyond that there is something very interesting for our scientists. Our astronomers are very interested in the gases found in interstellar space, the interstellar medium, the ISM. Recently, NASA’s Voyager-1 vehicle heard the sound of this interstellar medium. Very light noise The Voyager-1 spacecraft has landed in space outside of our solar system. You can always send signals from there. According to this study published in Nature Astronomy, the sound is much lighter, coming from the plasma waves of the interstellar medium captured by the interstellar spacecraft. Stella Coach Ocker, a researcher at Shamley Cornell University, said in the study that the narrow frequency band produces very light and attractive sound. What is happening in this interstellar mediumIn this interstellar medium, ionized, molecular and molecular gases, as well as stellar dust, have a cosmic form. The cosmic form is a combination of high energy molecular centers and protons that move all over space. These radiations, among other substances present in the interstellar medium, are extremely harmful to humans. The role of the heliosphere Our sun protects the universe from radiation by forming a heliosphere outside the solar system. It is a bubble that surrounds the solar system, preventing cosmic rays from entering the solar system, which are made up of charged particles from the sun. But the sun cannot stop them completely.

These radiations do not reach the surface of the Earth Cosmic rays also enter the heliosphere. In such a case, the Earth’s magnetic field and atmosphere change the direction of this radiation or make it ineffective. Now Wiser-1 has reached the heliosphere of the Sun. Density in space outside the solar system is increasing, so learn how to get this information In 2012, the solar system was overtaken Voyager 1 now faces the interstellar through the heliosphere. NASA launched Wiser 1 in 1977, which overtook our solar system in 2012. Visor was sent outside the solar system to explore the outer planets of our solar system, if possible.

The sound starts as soon as the heliosphere comes out Voyager 1 has traveled 38 billion kilometers so far, roughly 150 times the distance between our Sun and Earth. It takes 12 hours for the light to reach the earth. Since 2017, plasma waves at a distance of about 23 billion kilometers have echoed continuously. This plasma is a diffusing gas which is found in a particular state between the stars. Find out how Saturn became a weird and shaped magnetic field It’s like a kind of light rain of particles. This is due to the very moderate activity that occurs in the interstellar medium. We do not know what this activity is. This heat is caused by the oscillation of the plasma or the sound of virtual heat caused by the action of electrons in the plasma. However, this finding may reveal plasma concentrations in the interstellar medium.
