Scientists discover radio waves that sound like bird song
Scientists hunting 'killer electrons' that damage communication systems have discovered low frequency waves from space that sound like birdsong.

The Cambridge-based British Antarctic Survey is studying the waves to find out more about storms above the Earth.

In the morning, low frequency radio waves produced in space, travel down to the ground. A spokesman said: "They provide power for 'killer electrons'.

"We record the chorus waves to learn more about space weather processes."

The phenomenon occurs as the Earth and its enveloping atmosphere turn towards the sun.

Researchers will be recording the chorus waves to learn more about space weather processes and how shuttles can be protected from them.
