After a rough ride through the stargate to P39-865, the sun of that planet turns red. Carter deduces that an override of stargate protocols allowed them to create a wormhole through the sun, starting a reaction that will cause the sun to die. SG-1 must now make up for their mistake or P39-865 will become incapable of supporting life. Written by trekkie4christ

Did You Know?


Any second or later generation star, i.e. one that did not form immediately after the Big Bang, contains varying traces of heavy elements stemming from the Supernova remnants from which they formed. Though they may only make up very small percentages, in absolute terms, they amount to millions and millions of tons because stars are so massive. No amount of plutonium so small its effects could be offset by a rocket payload of some other element could ever make the slightest bit of difference to a star, not even the smallest one.

Who Saved the Inhabitants?
23 October 2016 | by (Rio de Janeiro, Brazil) – See all my reviews

The SG1 arrives on a planet with a primitive and superstitious population that worships Thor. The Stargate was blocked and the SG-1 has overridden the protocols creating a wormhole through the sun to go to the planet. They find a dying planet with a mysterious red sky. Samantha researches and finds that they have caused the phenomenon bringing a different mineral that has caused the modification of the sun. The SG-1 tries to revert the situation and contact the Asgard that explain that the Stargate was blocked to protect the civilization from the Goaul'd. However, the Asgardian refuse to help the people as part of the treat they made with the Gouaul'd of not interfering with the civilizations under their protection. Now the SG-1 has to find a means to save them.

"Red Sky" could have been one of the best episodes of "Stargate SG-1". But the episode is strange and without explanation about who saved the inhabitants of the planet. The SG-1 caused the problem; tried to help the locals; offered to bring them Earth; once they do not accept, Jack is right and they should have gone away. My vote is seven.
