Dubbed GRB 090423, the record-breaker is an example of a gamma-ray burst, the brightest and most violent explosions known to exist. The explosion is thought to accompany the catastrophic death of a very massive star as it ended its life, and is triggered by the centre of the star collapsing to form a black hole. </P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.star.le.ac.uk/~nrt3/090423/">"This observation allows us to begin exploring the last blank space on our map of the Universe", said Professor Nial Tanvir, who led one of the teams.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.star.le.ac.uk/~nrt3/090423/"><div align="center"><img src="http://content8.clipmarks.com/blog_cache/www.star.le.ac.uk/img/E718D4F3-92F9-41A4-BB4C-34812C84AF9D" alt="" /></div></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.star.le.ac.uk/~nrt3/090423/"><H4>FURTHER INFORMATION</H4> <A href="http://www.star.le.ac.uk/~nrt3/090423/Nature.html"> Nature press notice</A> <P> <A href="http://www.star.le.ac.uk/~nrt3/090423/FAQ.html"> GRB 090423 background FAQ</A> </P><P> <A href="http://www.star.le.ac.uk/~nrt3/090423/Figures.html"> Figures from paper</A></P></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/80DCB7C2-3AFF-4B19-BB23-8ED96589F84E/blog/" title="blog or email this clip"><img src="http://content6.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
