Astronomers across 11 observatories on Hawaii’s tallest mountain have cancelled more than 2,000 hours of telescope viewing over the past four weeks because a protest blocked a road to the summit. Astronomers said Friday, Aug. 9, 2019, they will attempt to resume observations but in some cases won’t be able to make up the missed research. (AP Photo/Caleb Jones, File)
