Space

Space is a layer appearing at the top of the world: ~950 feet and above, for large worlds. Gravity is decreased in Space, which means the player can jump higher, and will fall slower, similar to the Featherfall Potion effect. The sky is dark and stars are visible, even when the Sun is still up.

As with all high-altitude locations, Harpies and Wyverns will spawn. Fallen Stars spawn in this environment and can appear inside structures made at that altitude. The only naturally occuring materials in space are Floating Islands and – in small worlds – Living Trees.

Space seems to simply be a higher and thinner atmosphere layer, as air apparently still exists, so the breath meter does not appear.

Possible methods of getting to Space are use of a Gravitation Potion, Wings, or building a pillar of Blocks. Rocket Boots will often get a player there when used from a Floating Island. You can also easily visit space in ghost form with a deceased hardcore character. Finally, simply building straight up with a vast quantity of rope will take you to the space level and also allow for a means of quickly sliding back down to earth.

As of the 1.2 update, the console exclusive Space Theme now plays on the PC. The theme can be recorded with a Music Box.
