That includes whether there’s life outside our solar system and how stars and galaxies formed in the earliest years of the universe. But some Native Hawaiians don’t want the Thirty Meter Telescope to be built at Mauna Kea’s summit, saying it will further harm a place they consider sacred. (AP Photo/Caleb Jones, File)
