There's nothing like crossing a continent to see an old friend, even if it's just for an evening. Peter moved to Switzerland for PhD studies. He researches a type of solar panel called prevoskites, and is working on ways to make them ready to deploy around the world.
It's a joy of a day. Peter brings us to Lac du Neuchatel for an afternoon of grilling and swimming. Then he introduces us to the glory of Doner Kebab. We hang out with his scientist friends and have the same old conversation: science has the power to save the world but also destroy it.
It's our choice. We need to ask our scientists and governments to act responsibly with their technology.
The sun sets and Jupiter rises over the lake. Lakes are great places to observe, especially if you can pick a spot on the northern side. Lakes mean that, as you look South toward the solar system (the ecliptic, the line where all the planets and the moon orbit), for miles in front of you there are really no lights.
It helps an extra bit when the Alps are just south of the lake.
Our scientist friends share a love of communicating science, so they shout out in French to the people who pass us by.
A swiss town late on a sunday doesn't draw a crowd, but we still share Jupiter's moons with a few happy people.
Here's a big cliffhanger: Jupiter's spot may be disappearing. It's time for us to race to Munich, where we will meet members of the Bavarian Public Observatory, to see Jupiter's red spot for the first and possibly only time in our lives.
