Hi Meg!
to IceInSpace!
The first advice I can give, is remember to call it "Astronomy", not "Astrology". The two are very different
The moon is a fascinating topic, and there's so much to learn. Start by observing the phases throughout the lunar calendar. Use the moonphase on the left (click on it) to get the rise and set times so you know when to observe it.
What else do you need to do for your blog? Just keep asking questions and we'll be happy to answer.
