An international team of astronomer detected cosmic waves with strange sound, In a space where they had never identified themselves before, surprising scientists.
These plasma bursts, called “coral waves” u Coral waves Cosmic, they drive at the same frequency as that of the human ear. When they become audio signals, their acute notes imitate the acute songs of birds.
Although researchers have already captured similar sounds in space before, creaky waves newly detected come much further: More than 100,000 kilometers from the earthwhere they had never measured before.
“This opens up many new questions about physics that could be possible in this area,” he said Allison JaynesSpace physics of the Iowa University.
What are these sounds?
Scientists are not yet sure of the way the disturbances occur, but they believe that the magnetic field of the earth can have something to do with that.
Although coral waves have been captured for decades, even by the receivers of a Antarctic research station In the 1960s, scientists still did not fully understand how they occur.
Even the twin space vessel, while Van Allen de la Nasa, heard the scarves of terrestrial radiation belts at a distance closer than the most recent detection.
It was theorized that the magnetic field of the earth could contribute to its training. The latest observations were captured by the Multi-scale magnetospheric satellites of NASALaunched in 2015 to explore the magnetic fields of the earth and the sun.
The discovery was published in the magazine Nature.
