Pan-STARRS1, Astronomical telescope at Haleakala Observatory, Maui County, US
Pan-STARRS1 is an astronomical telescope at Haleakala Observatory on Maui with a 1.8-meter mirror designed to survey the sky and detect celestial objects. It uses a specialized digital camera system to capture detailed images of distant stars, planets, and other astronomical phenomena.
Scientific observations began in May 2010, and the telescope has contributed to numerous astronomical discoveries since then. Most notably, it detected Oumuamua, an interstellar object that passed through the solar system.
Scientists from fourteen institutions across six countries collaborate at this facility, fostering international research partnerships in astronomical studies.
The site sits at high elevation on a volcano, providing excellent observing conditions but meaning access is limited to research personnel. The location's remote setting on Maui requires planning if you want to learn more about the facility from nearby visitor centers.
The camera system contains 1.4 gigapixels and uses five separate filters to observe the sky, allowing regular monitoring of roughly three quarters of the visible heavens. This capability makes it possible to track changes and discoveries across a vast portion of the night sky.
