It's time for the annual science fiction season to begin. Spring and summer are when giant science fiction flicks hit the screens, and even more giant science fiction conventions open their doors to the hundreds of thousands of light saber-wielding masses. New television series will debut (Clone Wars!), and old ones will restart (Battlestar!) Plus, you'll have a chance to snap up copies of awesome new books from Greg Egan, Karen Joy Fowler, Charles Stross, Ken MacLeod, and Nancy Kress. If you want to know where to go and what to do when you're in a science fictional way from April to August, then look no further than io9's exhaustive, amazing, intensive list of everything scifi this season.

Special Note: We have tried to list as much as possible here, but there are always things that will get left out. If you want to know every single book coming out this season, check out Locus magazine's exhaustive and ever-expanding list. And if you want to know about more cons, check the user-generated list at ConFinder, as well as the Ansible Events List (mostly UK). If you know of sites that list European and Asian cons, let us know in comments so we can add it here.
