Hopefully these will be little easier
.
The proper star names ones I think are prety tough but the Lunar Features and the People they are named after...
. They're people who really like a challenge!
I didn't mind the Spectroscopy ones I tried - pretty easy I thought for anyone with some knowledge or interest in spectroscopy, but might be a little more difficult to others.
Hopefully these will be a bit easier and more general, though I find the list I used to generate the clues seems a bit heavy on geological terminology
.
Anyway try these or the Spectroscopy puzzles if the Lunar and star names ones were too hard.
