Description: Just down from Haleakal?’s 10,023′ summit is a batch of telescopes. Among them is the impressive Daniel K. Inouye Solar Telescope.
Completed in 2017, the telescope sits above about 1/3 of the Earth’s atmosphere, giving it a great view of the sun’s surface. Learn more here: https://nso.edu/telescopes/inouye-solar-telescope/

If you’re wondering what an image from the observatory looks like, I found this on Wikipedia. It’s a sunspot, up close.

Location: Haleakal? National Park, Maui, Hawai’i, USA
