I can't wait for SGU!!! I was a bit gutted when they cancelled Stargate Atlantis. They ended it a bit soon i thought. I mean what happened to the Asgard's that were living in the Pegasus galaxy. We know that they were trying to get the Arterro device working so that it would cripple the Wraiths ability to travel round the galaxy. I was hoping that there was gonna be a great storyline where the Atlantis team was gonna have to do battle with them. Oh well lets just hope SGU is as good if not better.

Didn't the aasgard commit mass suicide at the end of stargate?

Leader of the Lost Tribe

About two years after the demise of the Asgard at their own hands in their home galaxy, Dr. Daniel Jackson and Dr. Rodney McKay encountered a splinter group of Asgard in the Pegasus Galaxy. The reason why these Asgard left their home was because they wished to conduct experiments on human beings in order to solve their cloning problem (human physiology is very close to the original form of the Asgard). The Asgard High Council forbade this type of experimentation, and this splinter group escaped in their intergalactic spaceships 10,000 years ago so as to avoid the Council's sanctions. Knowing that human life existed in Pegasus and that the Ancients and Wraith were distracted with the war, the Lost Tribe of the Asgard carried on their experiments without interference. Then, the Ancients lost the war and left Pegasus under the control of the Wraith. The Asgard had already formed several settlements by this time, and these settlements were targeted by the Wraith because they were technologically advanced. The Wraith destroyed the Asgard's intergalactic ships in the first battle. As a result, the Asgard retreated to a planet without a Stargate to hide within a poisonous atmosphere. At first they were able to survive this harsh environment with simple breathing apparatus, but over several thousand years, even their advanced armor-what the Asgard called "exoskeletons"-couldn't adequately protect them from their dying planet. As a result, they had to venture out into the galaxy once more, ever fearful that they would be found and destroyed by the Wraith. (Stargate Atlantis: 5.10 "First Contact Part 1", 5.11 "The Lost Tribe Part 2")

In their travels, they found a research facility built by the Ancients that housed an advanced weapon developed by the scientist Janus to fight the Wraith during the war. This same Janus was the one who had built a time machine inside a puddle jumper and was among the survivors who escaped through the Stargate to Earth when only those Ancients in Atlantis were left. Many of his projects were not approved by the Lantian High Council, so he built a secret lab in the lower level of one of the towers of Atlantis. Daniel and McKay were the ones who discovered this secret lab, and when they entered it, McKay's Ancient gene activated the dormant systems, including the key to the Attero Device (that's what the Wraith called this weapon). This key was connected through a subspace link to the main Device in the facility that the Asgard found, and as soon as they realized that they could eliminate the Wraith with this Device's full reactivation, they sent a ship and a team to Atlantis to retrieve both the key and the Ancient who had activated it. Because both Daniel and McKay were in the secret lab when the extraction team arrived, both were taken with the key to the facility on M6H-987. (Stargate Atlantis: 1.15 "Before I Sleep", 5.10 "First Contact Part 1", 5.11 "The Lost Tribe Part 2")

McKay reactivated the Attero Device after the Asgard threatened to kill them (Daniel was going to be the first to go because he was "not that kind of scientist"). Then, he discovered why Janus had abandoned the Device 10,000 years ago after a three-day trial: Not only had the Device destroyed Wraith ships as they entered hyperspace, which was its original design, but it also caused Stargates to explode when activated due to an energy build-up originating within the wormhole itself, which was the unfortunate and devastating "unforeseen side effect." Daniel attempted to reason with the Asgard twice: first, to not turn it on because it had some kind of unknown harmful side effect, and second, after it was turned on, to turn it off once the "unforeseen side effect" was discovered. The Asgard leader explained his dying race's desperate need to eliminate the Wraith at all costs, even if it meant the death of millions of others due to the use of the Stargates. Because of the leader's refusal to turn off the Device and to work with the Expedition on other alternatives, Daniel and McKay were forced to attempt to turn off the Device on their own, even if it meant their deaths. (Stargate Atlantis: 5.10 "First Contact Part 1", 5.11 "First Contact Part 2")

In the meantime, the "unforeseen side effect" was made very visible when the Stargate in Atlantis blew up. Fortunately, Atlantis had a shield that lessened the impact of the explosion, but people on other planets that were using Stargates at the time weren't so lucky. After a hundred generations living solely in spaceships, the Travelers were establishing a colony on a planet. The Stargate's explosion killed three thousand colonists and destroyed two of their spaceships, including an Ancient Aurora-class starship that they had salvaged with the help of the Expedition. (Stargate Atlantis: 5.11 "First Contact Part 2")

Daniel and McKay managed to gain access to the main chamber of the Attero Device itself by wearing the Asgard's exoskeleton suits (they had to enter the chamber because the Asgard had removed the key and locked them out of the control systems). Going into this room was extremely dangerous, and Daniel was hit by several bolts of electricity while McKay was protected long enough to disable the Device by yanking out its control crystal. Even though Daniel was wearing the armor, he was still severely injured. Fortunately for him, the Daedalus arrived at the planet in time to use its Asgard beaming technology to retrieve both him and McKay. The Travelers destroyed the facility. Two of the Asgard's ships were destroyed in a space battle to protect that facility, but a third ship managed to escape through a hyperspace window. Daniel predicted that these Asgard were most likely to hold a grudge since their plan to run free in the galaxy by eliminating the Wraith was thwarted

Who asked for your opinion you fucking nonse. Go do us all a favour and play on the motorway.
