MARCH 2026 Winner

Yanick Brassard : Medusa Nebula

His stunning capture of the Medusa Nebula impressed us with incredible detail, beautiful processing, and an outstanding final result.

The Medusa Nebula is a faint planetary nebula located about 1,500 light-years away in the constellation Gemini.

This intricate cloud of glowing gas was created when a dying star expelled its outer layers into space thousands of years ago. Its delicate filamentary structure and eerie appearance are what gave it the name “Medusa.”
