Star's pulse of radiation is strongest ever

The brightest pulse of radiation ever seen has come from a pulsar nearly 12,000 light years away. Lasting less than 15 billionths of a second (15 nanoseconds), the burst was recorded by a massive radio telescope at Tidbinbilla in Australia.

Although the star was discovered decades ago, it is only now that telescopes have become sensitive enough to record such a fleeting phenomenon.
