Asgard is the home of an advanced alien civilization in the Thor movies. Asgardians were worshipped by the Scandinavian peoples of the early middle ages due to their intervention when aliens from Jotunheim tried to invade Earth.
Asgardians are visually indistinguishable from humans, but they are far stronger and tougher. While some some Asgardians exhibit physical attributes that far exceed the norm for their race, even the mundane Asgardians can lift thousands of pounds and survive the impact of modern firearms.
Asgardian technology is vastly superior to modern Earth technology, to the point that it can easily be called "magic". Asgardians have created artifacts that can manipulate the weather over large areas, fire powerful beams of energy, and teleport man-sized objects over interstellar (possibly intergalactic) distances. Many Asgardian artifacts appear to be capable of responding to the thoughts of authorized users.
Asgardians prefer to engage their enemies in close combat, but this preference may be explained by their high durability, which makes range weapons less effective against them. They don't appear to have starships, but the "Bifrost" device (currently inoperative) gave them the ability to deploy troops in large numbers over vast distances in a matter of seconds. How they would actually fair in open war against a space-faring race is difficult to determine.
