Huge 'star-quake' rocks Milky Way

Astronomers say they have been stunned by the amount of energy released in
a star explosion on the far side of our galaxy, 50,000 light-years away.

The flash of radiation on 27 December was so powerful that it bounced off
the Moon and lit up the Earth's atmosphere.


The initial burst of high-energy radiation subsided quickly but there
continues to be an afterglow at longer radio wavelengths.

The upper atmosphere was affected. Low frequency communications was
supposed to be affected by this event but I could not find any further
descriptions.
