Phil Plait – astronomer, author, space and astronomy myth debunker, trumpeter of science. Oh, and should we also mention writer of the popular Bad Astronomy blog at Slate Magazine? After years of working with data from the Hubble Space Telescope, Phil has made a multi-faceted career of sharing his love of space science with the masses. To this end, Phil and his wife, Marcella, also founded Science Getaways, a vacation company offering holidays with science themes.

During his call in we’ll be auctioning off the Bad Astronomer Lot, which features a bunch of neat space-y stuff from NASA, SpaceX, and more!

Phil will be calling in on Sunday, at 1:00 PM PST, 4:00 PM EST, 9:00 PM GMT. If you have any questions for the call in leave them in the comments!
