The Stargate makes a return in Starcraft 2, with updated graphics and several new units. Here’s the official description from Blizzard’s website:

The warships of the protoss fleet require a much stronger warp link in order to materialize than a standard gateway can provide. The immense stargate is capable of calling ships from high orbit or across immense distances to appear on a planet surface. The construction of one or more stargates at a protoss base is a sure sign that it has become a major staging point for an offensive.

Stargates are used primarily for aerial units, with the ability to build carriers, scouts, corsairs, and arbitors in the original Starcraft Brood Wars. They will probably be the staging ground for several of the new units, including the Phoenix and the Mothership. Stargates are pretty high up on the tech ladder and usually come into play in longer games.
