GHOST Gemini captures the first beautiful light observations of a bright, chemical-rich star
Gemini South, one of the most productive and powerful infrared-optical telescopes in the world, received a major capability upgrade with the successful installation of a new high-resolution spectrograph called GHOST built by an international consortium. This cutting-edge scientific instrument will expand our understanding of the earliest stars, the chemical fingerprints of distant planetary systems, and the formation and evolution of galaxies. Gemini South in Chile is half of the Gemini International Observatory, operated by NOIRLab NSF. The latest scientific instrument from the Gemini South telescope — GHOST, Gemini High-resolution Optical SpecTrograph — achieved its first light by making excellent observations of HD 222925, a very bright and chemically complex star located more than 1,400 light-years to the south. hemisphere of the constellation Tucana. This star is a prime example of the type of object GHOST will investigate. Gemini South is half of the Gemini International Obs
