We visited Hawaii for our 2018 summer family vacation and we started on the Big Island.
We started our last full day with a lava boat tour that started at 4am in Hilo and returned to the dock at 7am.
We enjoyed a relaxed ride back to Kona via Highway 19.
Before the trip, and once we arrived, I thought about visiting the telescopes atop Manua Kea, but realized that there were too many clouds, too few hours in the day, and sadly too little interest among the other three family family members, so he was OK not going.
Then, as we drove home, we passed the Keck Observatory Visitor Center, in Waimea, and I quickly made a u-turn. I asked my wife and sone to let our daughter and me go in for just 5-7 minutes. Somehow that turned into 40 minutes, because it is pretty awesome!
The docents are fun and engaging and insightful.
We learned how they use adaptive optics to help ground-based see better, to see with clarity approaching that of the Hubble Space Telescope... they use a laser to measure distortions of the optics by the air in the sky and then apply that same math to "un-do" the distortion and make images of deep space objects more clear (this wording is all mine, not a quote from Keck).
We also learned that the Keck Observatory has:
⁃ discovered over 100 exoplanets and has recently helped to classify different types of exoplanets
⁃ seen through the gas cloud at the center of our Milky Way and see the stars swirling around the black hole - http://www.keckobservatory.org/g-objects/
⁃ helped discover dark matter
⁃ discovered the moon Dysnomia, around Eris, which is further from the sun than Pluto and bigger than Pluto, and which helped change the class of planet for Pluto (note... Pluto is still a type of a planet and deserving of that status; planets come in different kinds, just like stars do, and the demotion in 2006 was in part due to someone having personal dislike of Clyde Tombaugh, who discovered Pluto)
⁃ the Keck I and Keck II telescopes, which have 36 6-foot hexagonal mirrors and sit atop Mauna Kea, make two 10-meter (30-foot) telescopes
We had great visit and hope we can have more time to visit on our next trip! read more
