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."

NASA - New Gamma-Ray Burst Smashes Cosmic Distance Record
[ Ссылка ]
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). April 25, 2009" - SkyandTelescope.com

GRBlog: GCN 9283
"We observed the field of GRB 090429B (Swift trigger 350854; Ukwatta et al., GCN 9281) simultaneously in g'r'i'z'JHK with GROND (Greiner et al. 2008, PASP 120, 405) mounted at the 2.2 m ESO/MPI telescope at La Silla Observatory (Chile).
Observations started at 05:43 UT, ~13 minutes after the GRB trigger and continued until the source reached the 20 deg horizon limit. "

ESO - ESO 17/09 - The Most Distant Object Yet Discovered in the Universe
"The Most Distant Object Yet Discovered in the Universe
ESO's Very Large Telescope has shown that a faint gamma-ray burst detected last Thursday is the signature of the explosion of the earliest, most distant known object in the Universe (a redshift of 8.2). The explosion apparently took place more than 13 billion years ago, only about 600 million years after the Big Bang."

Gemini Observatory Releases Image of Most Distant Known Object in Universe | Gemini Observatory
"The burst as measured by Gemini and subsequent observations is at a redshift of z = 8.2, such a great distance that its light has been traveling for over 13 of the estimated 13.7 billion year age of the universe. "
