You've worked hard to get here, but you've done it - you've finished Level 1 of SkyServer's SQL tutorial. You now know enough to search SkyServer's massive database for just the data you need. Happy searching!
For more examples of SQL queries, see the Sample SQL Queries page. That page contains many queries that were written by SkyServer users (mostly scientists) to answer interesting science questions.
For more information about using SQL with SkyServer, including advice on how to make your queries run faster, see Using SQL with SkyServer.
Here are a few challenge questions that will give you more practice with SQL. With everything you now know, you should be able to write SQL queries to answer these questions. If you figure them out, E-mail the queries to us, and we just might put them up on these pages!
