GRB 250702B host galaxy

Caption

The faint oval at the center of this image is the host galaxy of GRB 250702B — the longest gamma-ray burst that astronomers have ever observed. This image was taken on 20 July 2025 by 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. It is the result of over two hours of observation, yet the host galaxy appears extremely faint due to the large amount of dust surrounding it.
