Thanos wanted the Tesseract because it is one of the six Infinity Stones. If all six stones are assembled the bearer gets godlike powers. In the comics Thanos wants that power to kill everybody in order to impress the personification of Death, who he is in love with.

Thanos (who is an alien) and the Guardians of the Galaxy are both generally associated with the cosmic/space section of the Marvel Universe. Also, in the comics at least, two members of the Guardians have connections to Thanos. They mention in the trailer that Drax's (muscle guy) family was killed; in the comics that was Thanos. Also Gamora (green chick) was raised and trained by Thanos.

So the Tesseract is one of the six Infinity Stones, the Aether (from Thor 2) is another one. There is a third one in Guardians of the Galaxy. Generally it's assumed that Avengers 3 will have to do with Thanos assembling all six and trying to kill everybody.

Awesome thanks!
