Deep Space is an EP of the band Eisley, released on February 14, 2012 on Equal Vision Records. Originally the EP was going to contain a few b-sides from The Valley, but the band ultimately decided to record mostly new songs and changed the way of the EP as an anticipation of their fourth full-length album. The song "192 Days" had previously been released in demo form on the band's EP Fire Kite in 2009.
