Wide-field view: Supernova SN 2026gzf in Sextans | Vera C. Rubin Observatory

Wide-field view of Star in Sextans: Pre-supernova | Vera C. Rubin Observatory

This image shows the field around the progenitor to supernova SN 2026gzf, detected by the Einstein Probe on March 21, 2026. The supernova progenitor appears as a bright blue dot within the galaxy located in the middle of the upper third at the center of this image.

This image was created by stacking multiple images taken between May 2025 and January 2026 with the LSST Camera, mounted on the NSF–DOE Vera C. Rubin Observatory, jointly funded by the U.S. National Science Foundation (NSF) and the U.S. Department of Energy's Office of Science (DOE/SC).

SN 2026gzf occurred within Rubin’s COSMOS Deep Drilling Field. Observations of this field, including this image, were recently made public as part of Rubin’s Early Data Preview 2 (EDP2) — the first data preview based on observations from the LSST Camera. EDP2 combines Rubin’s science validation observations collected between April 2025 and January 2026.
