The Path to Observation
2 December 2024
Star trails streak across the sky above the summit of Maunakea in this image, which shows the surroundings of the Gemini North telescope, one half of the International Gemini Observatory, supported in part by the U.S. National Science Foundation and operated by NSF NOIRLab. The long exposure time of this photograph, coupled with the rotation of Earth, has caused the stars to streak into a multitude of graceful arcs. To the right of the image a much more earthly trail is visible; hikers with head torches have illuminated the final stretch of the Humuʻula Trail which winds up to the summit of Maunakea.
One of the streaks of light in the skies above Maunakea didn’t originate from a distant star, but rather from something much closer to home. A passing airplane has left a dashed trail at the lower left of this image, pointing the way to the glowing patch of cloud illuminated by the city lights of Hilo, Hawai‘i.
