The instruments engaged in the spacecraft tried to understand these sounds continuously coming from the space. It is believed that this is the noise of the universe beyond our neighboring galaxy.
Voyager 1 Spacecraft (NASA)
The US Space Agency NASA’s Voyager 1 spacecraft (Voyager 1) has recorded a strange ‘hmm’ sound outside our solar system. Voyager 1 is such a human made object, which is located farthest from the earth. The pair of this spacecraft was launched 44 years ago to send it to the edge of the solar system. The Voyager spacecraft has crossed the edge of the Solar System during this time. It has reached that part of our solar system, where even our sunlight does not reach.
The instruments engaged in the spacecraft tried to understand these sounds continuously coming from the space. It is believed that this is the noise of the universe beyond our neighboring galaxy. It has been said about this noise that these are interstellar gas or plasma waves, which are present in the empty space between stars. Stella Koch Oker, a Cornell doctoral student in astronomy and detective of this noise, said that this sound is very slow and monotonous, because it has very low bandwidth frequency. We are trying to find out more information about this ‘hmm’ voice.
Is there any reason why the voice is not coming
This discovery shows that a lot is happening between the stars compared to the information of scientists. Scientists are not yet clear about what activity it is, due to which this noise is happening. But they feel that this is due to the vibration of thermal plasma. Researchers hope that they can try to understand things on the boundary of the solar system through Voyager. They also hope to understand how the outer atmosphere of space broadens the boundaries of the solar system.
Outer space a quiet place
When the Voyager 1 spacecraft reached the area beyond the solar system, it has detected gas disturbances, which are taking place in outer space. Our sun is responsible for this and this information will be sent to the earth. But during this period, he has also continuously detected a voice like ‘Hmm’. Jams Chords, senior author of ‘George Feldstein Professor of Astronomy’, said outer space is like a cold and slow rain. In the case of solar outbreaks, it is exactly like a thunder of electricity.
Voyager is 14 billion miles from Earth
NASA’s Voyager 1 is 14 billion miles away from Earth, and the distance is increasing every day. Because of this, it can send only a limited number of information back to the earth. With this spacecraft, scientists get only 160 bytes of information every second. When this spacecraft was launched, it could send information up to 21 kilobytes. Voyager information is transmitted through the deep space network on Earth. Deep space networks are spread around the earth like a dot.
