I’m a big fan of Astronomy magazine, because it’s loaded with terrific articles and images that help to explain some of the most mind-blowing elements of space science in very easy-to-understand language.
And they have a fantastic site that kids will love.Here’s a link that will take you to that particular page. Teachers will especially find this useful when they do a unit on science/space.

Hi, Dom,
Thanks for the nice plug. Two other features teachers might find useful on the
site:
-Our interactive star chart, StarDome, maps the objects visible in your night
sky, and
-Our weekly podcast (www.Astronomy.com/Podcast) highlights a naked-eye object
visible in the night sky and gives you tips on how to see it.
These are just two of Astronomy.com’s free features teachers can use in the
classroom to explain the, as you call them, “mind-blowing elements of space
science.”
Thanks, again, Dom!
-Matt
You told me this was an amazing magazine, I should check it out. I’m excited
by the other free features for teachers and am excited to gather some things
for our space unit and astronomy at Outdoor Lab.
