Protesters are opposing the construction of a new telescope atop Mauna Kea in Hawaii — again.
Progress on the Thirty Meter Telescope, or TMT, stalled earlier this year after some protesters were arrested on the summit of Mauna Kea on the Big Island.
The mountain ticks all the boxes for a perfect astronomy location. It's more than 12,000 feet up, above much of the visual interference from Earth's atmosphere. Air and light pollution are minimal, skies are clear some 300 days a year and Hawaii is close to the equator, meaning a wide arc of both the Northern and Southern hemispheres is visible from the ground.

But there are already 12 scopes at or near the summit of Mauna Kea, and some native Hawaiians have opposed new construction on ground they hold sacred.

In a statement, TMT officials say they've spent the recent idle months in dialogue with stakeholders.

If construction proceeds, the TMT will be on track to come online sometime in 2022.
