MAUNA KEA, Hawaii (AP) — Native Hawaiian groups vowed to protect Hawaii’s tallest mountain from an attempt to resume construction of a giant telescope.

They said they will gather peacefully at the base of Mauna Kea. The road to the summit will be closed today morning as trucks carrying construction equipment start to make their way to the peak. Scientists hope the massive telescope they plan to build atop Mauna Kea, a world-renowned location for astronomy, will help them peer back to the time just after the Big Bang and answer fundamental questions about the universe.
