Welcome to "Explore Galaxies," a library of content all about galaxies and astronomy drawn from content all over the internet. On these pages you'll find an astronomy glossary, information on the space missions and telescopes we use in our research, and quick descriptions of a lot of the science terms you'll see used in our blogs and forums. We hope to keep this site constantly updating based on what you are searching for. Check back often to see what is new in this and other galaxies.
