A controversial telescope originally planned for the summit of Mauna Kea in Hawaii has been offered a new home in Spain. The Canary Islands Astrophysics Institute in La Palma has received building permits for constructing the $1.4-billion Thirty Meter Telescope, which has been blocked since July by Native Hawaiian groups who consider the 13,800-ft-tall peak to be sacred. Mauna Kea already hosts 13 other observatories and remains the preferred location for what would be the world’s largest visible-light telescope. The international consortium of universities sponsoring the project has yet to decide whether to accept the relocation offer, which would allow the ten-year construction project to get underway in early 2020.
