X-World/5-New Universal Order
Now this certainly isn't the worst outer space/spaceship type cover of all time. However, considering it was done in 2008 you would think they could have done better. It looks like part of the old Battlestar Gallactica only the artist misjudged it and couldn't fit the whole thing on the cover. Or perhaps the band thought it would be a real clever idea if they had a spaceship advertising their band name on the side like it was a city bus or something.
