Strong deep-space signal startles astronomers

A team of astronomers has detected a huge burst of radio energy from deep space 
while using the Parkes radio telescope in NSW.

The huge burst of energy, which has startled scientists with its strength, is 
thought to have originated over 500 mega-parsecs or one-and-a-half billion 
light years from earth.

Professor Matthew Bailes of Swinburne University in Melbourne said that the 
burst was unusual as this kind of activity was usually very faint at such 
extreme distances.

"Normally the kind of cosmic activity we're looking for at this distance would 
be very faint but this was so bright that it saturated the equipment," he said 
in a statement.

The burst of energy, which lasted for only five milliseconds, was so strong 
that when it was first detected six years ago it was dismissed as man-made 
interference.

The significance of the burst was discovered by David Narkevik, an 
undergraduate from West Viginia University, when he re-analysed the 
six-year-old data collected at Parkes.

Lead researcher Assistant Professor Duncan Lorimer from West Virginia 
University said that the burst may have been a result of two stars colliding or 
the death of a black hole.

"The burst may have been produced by an exotic event such as the collision of 
two neutron stars or be the last gasp of a black hole as it evaporates 
completely," he said.

The amount of energy thrown out by the burst was 10exp33 joules or the 
equivalent to the amount of energy that around 185.3 billion average Australian 
homes would use in a year.

The full report of the discovery will be available today in the online journal 
Science Express.
