It's not a resource
per se, but I probably should have mentioned the Astronomy Picture of the Day
, run by NASA
, which features a different space related picture every day. As you can see, some of these are amazing works of art in their own right, but with the accompanying blurb you can also learn some science while you're at it. The official site doesn't have an RSS feed unfortunately, but Jef Poskanzer
has put together an unofficial feed
which you can use to get your daily helping easily.
