The nonprofit organisation that wants to build a giant telescope atop a Hawaii mountain has selected another site in case it cannot be built on land many Native Hawaiians consider sacred.

A mountain in the Canary Islands, Spain, is the primary alternative to Hawaii, Thirty Meter Telescope (TMT) officials announced on Monday.

Hawaii's Mauna Kea is still the preferred location and telescope officials will forge ahead in efforts to obtain a permit to build it on conservation land.

The project is stalled in Hawaii amid intense protests by Native Hawaiians and others who cite the sacredness of the land and other issues for their opposition. The state Supreme Court last year invalidated the project's permit, ruling that the state land board's approval process was flawed. The ruling sent the matter back for a new contested-case hearing.

The hearings have been moving slowly since they started on October 20 after various delays.

"I'm glad they're looking at alternative sites," Kealoha Pisciotta, one of the leaders challenging the telescope, said during a break in the hearings. "I have to say if they do go with the alternative site, I hope they don't do there what they're doing to Native Hawaiians and the people of Hawaii."

Telescope officials earlier this year decided to start looking at other sites for the $1.4 billion project. They also considered high mountains in Chile, India, China and Mexico.

Observatorio del Roque de los Muchachos is on the edge of the Caldera de Taburiente National Park, about 7,800 feet above sea level.

Telescope officials selected Mauna Kea over Chile's Cerro Armazones mountain in 2009. Astronomers prefer Mauna Kea because its nearly 14,000-foot summit is well above the clouds, and it provides a clear view of the sky for 300 days a year. There's also very little air and light pollution.
