GRB 090423: probably the birth of a black hole / Credit: Science@NASA NASA - New Gamma-Ray Burst Smashes Cosmic Distance Record ""We're seeing the demise of a star -- and probably the birth of a black hole -- in one of the universe's earliest stellar generations," says Derek Fox at Pennsylvania State University." science.nasa.gov New Gamma-Ray Burst Smashes Cosmic Distance Record www.nasa.gov NASA - New Gamma-Ray Burst Smashes Cosmic Distance Record www.nasa.gov A faint gamma-ray burst (GRB) captured last Thursday by NASAs Swift satellite has smashed the record for the earliest, most-distant known object in the universe. "The GRB's measured redshift of about 8.2 beats the previous GRB record holder, a burst seen last year with a redshift of 6.7. T he most distant galaxy with a well-measured redshift is at 6.96. NASA says it will issue a statement about the discovery on Tuesday (April 28th).

Observations started at 05:43 UT, ~13 minutes after the GRB trigger and continued until the source reached the 20 deg horizon limit.
