The Beta Gate in Antarctica.

"Remember, the [Stargate] that Ra put here might not have been the first. The Goa'uld didn't build the Stargate system."
Daniel Jackson[src]

The Beta Gate, also referred to as the Antarctic Gate, was a second Stargate discovered on Earth. It was found in 1998 by Samantha Carter and Jack O'Neill inside a glacier in Antarctica.

The Beta Gate was the planet's original Stargate, having been placed there by the Ancients millions of years ago during their original habitation of Earth. As such, it is one of the oldest known Stargates in the entire Milky Way galaxy Stargate Network, theorized as being as much as 50 million years old. It, along with an outpost, was left behind (in a region that would become Antarctica) when the Ancients left for the Pegasus galaxy in Atlantis. (SG1: "Solitudes", "Frozen") (SGA: "Rising")


The Beta Gate was discovered purely by accident by Colonel Jack O'Neill and Captain Samantha Carter when an energy blast overloaded the Stargate on P4A-771. This energy blast caused the wormhole to "jump", redirecting it from the Alpha Gate to next closest gate, which was, in this case, the Beta Gate. (SG1: "Solitudes")

Touchstone (Stargate SG-1)

The Beta gate as used by the NID.

Once removed from Antarctica, it was taken to Area 51 and put in storage. After an accusation of an SG team stealing the Touchstone from Madrona, Carter discovered the Beta Gate was secretly being used by a covert NID team. SG-1 then traveled to Area 51 to verify it was still in storage. Upon inspection, however, they found it had been replaced with a plastic replica. The real Stargate was later located in an aircraft hanger in Utah and was promptly recovered and returned to Area 51. It was then fitted with a permanent iris to prevent future unauthorized use and was placed under the direct guard of the SGC. (SG1: "Touchstone") While there, the DHD was used a few times before ultimately and permanently running out of power. (SG1: "Frozen")

In 2002, SG-1 returned to the site where the Beta Gate was originally located. A research base was established near the location, tasked, in part, with determining whether the Beta Gate was in fact Earth's original Stargate or if it had been moved to Earth from another planet in the galaxy. (SG1, "Frozen")

X-302 explodes

The Beta gate explodes over 3 million miles from Earth.

The Beta Gate would remain in storage until SG-1 beamed the Alpha Gate from Stargate Command onto Thor's ship, the Biliskner, as a means of escaping the ship before it was destroyed. As Stargate Command now lacked a Stargate, General George Hammond immediately ordered the Beta Gate to be unpacked and setup at Stargate Command, as to allow for SG-1 to return home and Stargate operations to resume. The SGC continued using this Stargate until Anubis destroyed it with the Stargate destroyer. (SG1: "Nemesis", "Small Victories", "Redemption, Part 2")

Doom Island GateEdit

Island of Doom Stargate

In an alternate universe, there's a Stargate on the Island of Doom in the South Pacific. The islanders had been visited by Ra ages ago and still worshiped him, awaiting his return. This gate was presumably destroyed when the island was nuked by the U.S. Government. (Stargate: "Doomsday World 1", "Doomsday World 3")

Yucatán GateEdit

After being chased by creatures and visiting an ice planet, Gus Bonner's team begins to wonder if they are on a pointless quest. Draga opens a gate to "where they wish to go" and they end up on Earth in the Yucatán, where a local professor working for a Horace Van Gelder reveals she discovered the new gate. The shape-shifter Nephestis, disguised as Grimes, is working with Van Gelder and gets word the team is present when they contact Stargate Command. Disguised as Stoneman, Nephestis welcomes them and claims he'll help them clear their names, then summons Da'kyll and his Tlak'kahn. Draga suspects something as Stoneman sends the cadets into Cancun – in fact it's an ambush but they turn around and return. Gus and Draga catch on and make their escape while the others return just in time to rescue them. The team is forced to escape through the Gate and go on the run once more before they can clear their names, and the Tlak'kahn and Nephestis depart with Van Gelder as Nephestis takes his place to further implicate the team. (INF: "The Long Haul")

Alternate timelineEdit


Behind the scenesEdit

Throughout episodes in which the Beta Gate is installed in Stargate Command's Embarkation room (from "Small Victories" to "Redemption, Part 2"), its point of origin symbol is the same as for the Alpha Gate. Presumably, this is not canon, and is instead a production issue caused by reusing the same prop for both Stargates. As shown in "Solitudes", the point of origin for the Beta Gate is 0eb.
