The Sphere
From Tardis Wiki, the free Doctor Who reference
A Void Ship is a spacecraft designed to explore the Void that exists between dimensions. It appears as a solid gold sphere with no lines until it is opened, at which point its sides fold down to reveal the occupants. There was no sign that the ship could touch ground.
When travelling through the Void, it was removed from time and space and until it activated, had no detectable mass, heat or radiation, though it was visible. An invisible barrier prevents anything from touching the ship.
It was thought to be impossible, but it did exist. The only known Void Ship was used by the Daleks of the Cult of Skaro to escape the Time War with the Genesis Ark. It is unknown if they built it themselves. (DW: Army of Ghosts / Doomsday)
