The Gamma-Ray Burst Optical/Near-Infrared Detector (GROND) is an imaging instrument used to investigate Gamma-Ray Burst afterglows and for doing follow-up observations on exoplanets using transit photometry.{{cite journal |title=OGLE2-TR-L9b: an exoplanet transiting a rapidly rotating F3 star |url=http://www.mpe.mpg.de/~saglia/journals_pdf/snellen2009.pdf |last1=Snellen |first1=I.

Discoveries
- On 13 September 2008, Swift detected gamma-ray burst 080913. GROND and VLT subsequently placed the GRB at 12.8 Gly distant, making it the most-distant GRB observed, as well as the second-most-distant object to be spectroscopically confirmed.{{cite press release

- On 15 September 2008, NASA's Fermi Gamma-ray Space Telescope detected gamma-ray burst 080916C. On 19 February 2009, NASA announced that the GROND team's work shows that the GRB was the most energetic yet observed, and 12.2 Gly distant.{{cite press release
