Doing science writing, and being an astronomer, and working with planetarium facilities does have its upside when it comes to traveling: you get to travel around a lot! I ran across this site that allows you to create your own visited country map by clicking through on a form. This is my own travel map, showing where I’ve been (in red). Clearly I have a lot more places to visit!
Much of my travel in North America has been to planetarium and astronomy conferences, and also to amateur star parties (as a guest speaker). The European visits are a mix of vacation and professional meeting trips. I’d like to get to the other half of the world sometime!
A note about southern hemisphere travel: one of the coolest things you’ll ever see from below the equator is the night sky. It is simply stunning, as we found out during our trips to South America. The view just boggles the mind! For some great views of the southern hemisphere sky, visit MrEclipse.com and prepare to be amazed!
