Gemini Observatory's 25th Anniversary Celebrated with Stunning Butterfly Nebula Image

The International Gemini Observatory has marked its 25th anniversary with a stunning new image. The Butterfly Nebula, a bipolar formation in the constellation Scorpius, was captured by the Gemini South telescope in Chile. Schoolchildren in the country helped choose this celestial object for the celebration. The International Gemini Observatory has been operating for a quarter of a century. It includes the Gemini South telescope, which is run by the National Science Foundation’s NoirLab. The new image was taken in August 2023.

The Butterfly Nebula lies between 2,500 and 3,800 light-years from Earth. At its centre sits a white dwarf star that has shed its outer layers of gas. The heat from this star makes the discarded material glow, creating the nebula’s distinctive butterfly-like wings. The observatory selected the Butterfly Nebula to celebrate its milestone. The image highlights the nebula’s intricate structure and the role of the white dwarf in shaping it. This marks a significant moment for both astronomy and public engagement in Chile.
