The National Science Foundation’s Daniel K. Inouye Solar Telescope is the most powerful solar telescope in the world. The Inouye Solar Telescope is located at Haleakalā Observatories site on the island of Maui, Hawaiʻi. It was built and is operated by the National Solar Observatory (NSO) – a research center operated by the Association of Universities for Research in Astronomy (AURA) under a cooperative agreement with the National Science Foundation Division of Astronomical Sciences.

The Inouye Solar Telescope uses the largest mirror of any solar telescope in the world. At 13 feet (4 meters) across, it collects seven times more sunlight than any other solar telescope, producing the clearest, highest resolution images of our Sun ever taken.

The Inouye Solar Telescope’s primary objective is to observe magnetic fields on the Sun in order to understand its dynamic behavior. The Sun’s magnetic fields are the source of solar flares and coronal mass ejections, otherwise known as space weather which can impact Earth and hurt our technology such as electric and communication networks.
