How about an evening to celebrate science and good old scientist Carl Sagan, who died in 1996? Richmond’s own funky singer Kenneka Cook will perform music sure to get a little spacey, plus there will be a group science and space-themed art show upstairs. Also some of Richmond’s best science minds will tell stories about how Sagan inspired them. Plus there’s a Sagan costume and impersonation contest that should be fun. All proceeds go directly to support Thomas Jefferson High School planetarium rebuilding efforts. 8 p.m. $10 at the door. galleryfive.org.
