Sen: Ancient Radioactive Lunar Volcano

For my fortnightly column at Sen.com this go-round, I had a lot of fun writing about an ancient lunar volcano’s explosive eruption eons ago, the extent of which was mapped using gamma rays from radioactive thorium buried under billions of years of impact-produced lunar dust.

So yeah, I had a lot of fun. Sometimes just researching an article is pretty cool.

As I’ve said before, while the news and other sections at Sen are free, the blogs are subscription only. But if you look at the bloggers there, you’ll find that the price is totally worth it. You’d spend more than that on a book by just one person. And for that you’ll get to read lots of people covering lots of space. Literally.

It's a fan thing
