Many around the nation -- from Hawaii to New York, politicians to Hollywood stars -- voiced their opinion on the controversial Thirty Meter Telescope (TMT).

Well one in particular, a local boy some call 'Aquaman' -- made it a point to head back to Hawaii. Jason Momoa isn't quiet about his arrival or his stance on TMT.

Momoa wrote in an Instagram post, "I encourage all my OHANA friends and fans to show the world that we are not backing down from TMT --we are and will always be Non-violent and Aloha --so if they come at us we will stay in Peace but we will stand!"

He also asks everyone around the world to 'spread the awareness and aloha.'
