Everything about Grb 080319b totally explained
GRB 080319B was a remarkable
gamma ray burst (GRB) detected by the
Swift satellite at 06:12
UTC on
March 19 2008. The burst set a new record for the farthest object that could be seen with the
naked eye, it had a peak
apparent magnitude of 5.8 and remained theoretically visible for ~30 seconds. The magnitude was brighter than 9.0 for ~60 seconds.
The GRB's
redshift was measured to be 0.937, which means that the explosion occurred about 7.5 billion (7.5×10
9) years ago, and it took the light that long to reach us. This is roughly half the time since the
Big Bang. on the event, suggested that the GRB could have easily been seen to a
redshift of 16 (essentially to the time in the universe when stars were just being formed, well into the age of
reionization) from a sub-meter sized
telescope equipped with near-
infrared filters.
The afterglow of the burst set a new record for the "most intrinsically bright object ever observed by humans in the universe",
It was speculated that the afterglow was particularly bright due to the gamma jet focusing directly in our direction..
Until this gamma ray burst event, the
Triangulum Galaxy at a distance of about 2.9 million light years was the most distant object ever visible to the naked eye. The galaxy remains the most distant permanent object viewable without aid., as it occurred just hours after the death of noted science fiction author
Arthur C. Clarke was announced.
