Volcano picked as scope site
America's National Science Foundation has picked Maui’s Haleakala mountaintop in Hawaii as the site for the world’s largest solar optical telescope.
The US government agency picked the dormant volcano last week and the $300m (€200m) project will be built on half an acre among a cluster of observatories near Haleakala’s summit.
It will enable scientists to observe sunspots, flares and other phenomena too small to be seen with current equipment.
