- timr 1y agoI didn’t say it was. It’s still orders of magnitude cheaper than maintaining an entire telescope complex on top of a Hawaiian island.
- teamonkey 1y agoI think you’re thinking of the complex on Mauna Kea (which has several individual sites and has funding from several countries). Mauna Loa has a telescope that studies the Sun in order to help understand better how that contributes to changing weather patterns on Earth. It is a relatively small site but very important. The reason that telescopes are often in high up, hard to reach places is because that is the most efficient, cost-effective place for them to be.
