The Mauna Kea protests are gaining star power as Native Hawaiian groups continue to block construction of the Thirty Meter Telescope.
Astronomers want to build a telescope they say would change the way we know the universe. Hawaiians are fighting to preserve their culture and land.
The actor joined protesters who are protecting Mauna Kea, a mountain sacred to Hawaiians, from a massive project known as the Thirty Meter Telescope.
The $1.4 billion Thirty Meter Telescope set to be built atop Hawaii's tallest peak has been the subject of controversy for a decade.
The Thirty Meter Telescope, set to be the largest in the world, will be built on Mauna Kea despite years of protests and a Supreme Court battle.
The court upheld a building permit for the $1.4 billion Thirty Meter Telescope atop Mauna Kea, a mountain considered sacred by many Native Hawaiians.
A snowstorm hit the Big Island's summit, and more snow is expected.
Many Native Hawaiians oppose additional construction on Mauna Kea, a mountain which they consider sacred.
Don't be fooled: Hawaii is not an up-and-coming ski destination.
It doesn't get much more epic than this.
