How is the aurora started? Will it ever end?
The aurora was “started” a long, long time ago when our planet first developed an atmosphere (air you breath) and a magnetic field. There is almost always aurora somewhere in the North and South Pole, but how active it is depends on the particles that flow from the sun, called the solar wind. The aurora may end if Earth’s magnetic field disappears and it will end for sure when the sun dies. But the sun will not die for another 5 billion years, so do not worry about that! Dr.
