Gemini Observatory Celebrates 25 Years with New Nebula Discovery

The Gemini Observatory celebrates its 25th anniversary with the discovery of a new nebula named Ua Ohia Lani, which translates to the Heavenly Ohia Rains. This nebula is an emission nebula known as NGC 6820 and is associated with the open star cluster NGC 6823, located 6,000 light-years away in the constellation Vulpecula.

The image was released on November 19, 2025, and showcases the nebula's vibrant colors, primarily red due to the abundance of hydrogen gas, alongside hot, massive stars shining as blue-white specks. The image, reminiscent of the iconic Pillars of Creation, was captured using the Gemini North telescope situated on Maunakea, Hawaii.

The name Ua Ohia Lani was chosen by four local high school students participating in the University of Hawaii's Project Hokulani summer internship. The story behind the name aligns with Hawaiian mythology, reflecting themes of renewal and the cycle of stellar life, death, and rebirth.

Hope Arthur, one of the interns, noted that the crimson color of the nebula is likened to lava, relating to the goddess Pele in Hawaiian religion. The International Gemini Observatory consists of twin 8-meter telescopes, with the Gemini South located in the Chilean Andes, providing astronomers with expansive access to the night sky.
