Astrophysics: Most distant cosmic blast seen
Bing Zhang1
Abstract
The most distant 
-ray burst yet sighted is the earliest astronomical object ever observed in cosmic history. This ancient beacon offers a glimpse of the little-known cosmic dark ages.
In this issue, two papers1, 2 report the discovery of a -ray burst (GRB) at a redshift of about 8.2.
