The World's Largest Solar Telescope Snaps Its First Photograph (sciencemag.org) 14
sciencehabit quotes Science magazine: A new close-up of the turbulent boiling plasma of the solar surface is the debut image of the largest telescope ever built for staring at the Sun. Sporting a 4-meter-wide mirror — twice the size of any existing solar scope—and a vantage point 3000 meters up on the summit of Haleakala on the Hawaiian island of Maui — the Daniel K. Inouye Solar Telescope (DKIST) will reveal unprecedented detail of processes that channel energy from the Sun's interior into its atmosphere, the corona.
Researchers hope that by zooming in on cell-like structures — each about the size of Texas — they can learn what causes the Sun to launch powerful flares out into space, potentially causing damage to Earth's satellites, power grids, and communications. Such information could help scientists give warnings of such events days rather than minutes ahead.

No, that was Trump looking into the sun without any gizmo.

This telescope is on Haleakala, not Mauna Kea. There do not appear to be any disputes about telescope-construction on Haleakala. Mauna Kea is another matter, though. [wikipedia.org]

The Haleakala telescope site was protested too. Before the Hawaiian sites were protested, Deep Greens vainly protested installing large telescopes in southern Arizona.
Who are these people really, and what is it up there that they don't want us to see?
Haleakala, Not Mauna Kea (Score:2)
1) The University of Hawaii owns outright the 19 acre Haleakala Observatory land. So, unlike the lease of state land it holds for the 12000 acre Mauna Kea observatory reserve, it doesn't have to put up with as much crap from the rest of the state government, never mind Hawaiian sovereignty activists.
2) The term is "Ceded Lands", in that land formally held by the Hawaiian sovereign was ceded first to the Republic, then Territory, and finally State of Hawaii to be held in trust for the people of Hawaii.

Since their ancestors didn't visit the peak with any regularity, never constructed a temple anything else there, never left offerings of any type, and the supposed "sanctity" of the peak is not mentioned in their legends then the current "controversy" is rather blatantly manufactured. Some are trying to launch their political careers, and others just want the same handouts that the resorts give when they build on sites that had **actually** been occupied by ancient Hawaiians. Unfortunately the scientists
