AT THE EDGE OF THE UNIVERSE

Dear Ed

<A href="http://news.bbc.co.uk/1/hi/sci/tech/4237800.stm" target=_blank>Try this if you are interested in the most distant cosmic explosion o­n record: a gamma-ray burst that has come from the edge of the visible Universe

The record gamma-ray burst, 13 billion light-years from Earth, was detected o­n 4 September, 2005, and lasted about three minutes. It probably marked the death of a massive star as it collapsed into a black hole.

<FONT color=navy>Cosmic blasts are the most powerful explosions in the Universe and scientists think a 10-second burst near Earth could deplete up to half of the planet's ozone layer.
With the ozone layer devastated, the Sun's ultraviolet radiation could kill off much of the life o­n land and near the surface of oceans and lakes.
