Field around GRB 250702B

Caption

The stellar field around the host galaxy of GRB 250702B — the longest gamma-ray burst that astronomers have ever observed. It comprises observations from the Gemini North telescope, one half of the International Gemini Observatory, funded in part by the U.S. National Science Foundation and operated by NSF NOIRLab, as well as the U.S. Department of Energy-fabricated Dark Energy Camera, mounted on the NSF Víctor M. Blanco 4-meter Telescope at Cerro Tololo Inter-American Observatory, a Program of NSF NOIRLab.

The DECam data were acquired on 3 July 2025. The Gemini North data were acquired on 20 July 2025.
