The stratosphere extends in the range of 10 to 50 kilometers from the surface of the earth. Scientists sent a solar powered balloon here, in which it was found that some mysterious sounds are happening here. Surprisingly, it has been said that there is no idea of these voices from where they are coming. the washington post Report According to, these sounds are infra sound. Means such sounds which are beyond the hearing power of man. Just as we cannot see infrared light, similarly these sounds cannot be heard. These are some such sounds as if someone is making a muffled whisper. They are very mysterious.
According to the report, Siddhartha Krishnamurthy, research technologist at NASA’s Jet Propulsion Laboratory in Pasadena, California, told that they have spent a lot of time debating about these mysterious sounds. Another researcher Mr. Bauman told that he has been doing this work for the last 10 years but he is unable to find anything about these voices. He and his friends had earlier also sent such balloons to take photographs of the black sky above the earth.
But till now no one had tried to know the voices here. In the meantime, it occurred to him that in more than half a century no one had tried to listen to the sounds here by placing microphones in stratospheric balloons. These balloons are said to be able to carry sensors up to twice the maximum altitude of a jet plane. However, scientists are trying to find out from where these sounds are being generated.
