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.
