Gemini North mirror reflections at sunset. An extraordinary sunset view over the Gemini North primary mirror captured by Canadian astronomer, and Gemini user, Stéphane Courteau. While a strikingly beautiful photograph, it is also quite intriguing, especially the blue oval in the middle of the mirror — a reflection of the sky through the vent gates. The Gemini Observatory is operated by the Association of Universities for Research in Astronomy, Inc., under a cooperative agreement with the National Science Foundation on behalf of the Gemini Partnership.
