Scientists have detected the waves of the universe, which sounds like a bird sounding in an unexpected place.
These plasma bursts, called chorus waves, spread at the same frequency as human hearing.
When converted to an audio signal, the sharp note mimics a high -pitched bird call.
Researchers have previously captured such sounds in such a universe, but now they have sensed the charp waves far away. It is over 62,000 miles (100,000 kilometers) from the earth.
“There are many new questions about physics that can be possible in this field,” said the University of Iowa University, Alison Jeans, who was not involved in this job.
Scientists do not know how to be carried out yet, but the earth's magnetic field is related to it.
The chorus has been picked up on the radio antenna for decades, including receivers at Antarctic research station in the 1960s.
The twin spacecraft of NASA's Van A Lump Robe heard a charp from the radiation of the earth near the latest detection.
The latest notes were featured by NASA's magnetic multi -scale satellites released in 2015, exploring the magnetic fields of the earth and the sun.
New study Released on Wednesday At Journal Nature.
Chorus waves have been found near other planets such as Jupiter and Saturn.
They can even generate high -energy electrons that can scramble satellite communication.
“They are one of the strongest and most important waves in the universe,” said BEIHANG UNIVERSITY CHENGMING LIU.
The new chorus wave was detected in the area where the earth's magnetic field was stretched, but scientists did not expect.
It makes a fresh question about how these chicken waves are formed.
“It's very attractive and very attractive,” said Jane's.
“I need to find more of these events.”
