GRB 080913 was a gamma-ray burst (GRB) observed on September 13, 2008. The Swift Gamma-Ray Burst satellite made the detection, with follow-up and additional observations from ground-based observatories and instruments, including the Gamma-Ray Burst Optical/Near-Infrared Detector (GROND) and the Very Large Telescope. At 12.8 billion light-years and redshift of 6.7, the burst was the most distant GRB observed until GRB 090423{{cite web | title=Astronomical Artifact: Most Distant Object Yet Detected Carries Clues from Early Universe | url=http://www.scientificamerican.com/article.cfm?id=most-distant-grb | work=Scientific American | access-date=2010-02-23}}{{cite web|title=The Farthest Thing Ever Seen |url=http://www.skyandtelescope.com/news/43700627.html |archive-url=https://archive.today/20120914143629/http://www.skyandtelescope.com/news/43700627.html |url-status=dead |archive-date=2012-09-14 |work=Sky Publishing, Sky & Telescope |access-date=2010-02-23 }}{{cite web | title=Most distant object in the universe spotted| url=https://www.newscientist.com/article/dn17035-most-distant-object-in-the-universe-spotted.html | work=News Scientist | access-date=2010-02-23}}{{cite web | title= Breaking News | url=http://www.solstation.com/x-objects/grb000131.htm | work=Sol Station: Gamma-Ray Bursts 000131 - 090423 | access-date=2010-02-23}}{{cite web | title= More Observations of GRB 090423, the Most Distant Known Object in the Universe | url= http://www.universetoday.com/2009/10/28/more-observations-of-grb-090423-the-most-distant-known-object-in-the-universe/ | work=Universe Today | date= 28 October 2009 | access-date=2010-02-23}} on April 23, 2009.
