Jason Aaron and Esad Ribic will form the creative team for the Marvel NOW! title.
The pair were the subject of a teaser last week featuring the word "Worthy".
"This first story is an epic tale that plays out over the course of thousands of years," Aaron told Newsarama. "So we spend time with young Thor in the Viking age - the young, hotheaded god of the Vikings, who loves to come down to Midgard and get into trouble.
"In the present, we see Thor the Avenger on a journey that takes him to the far corners of space, interacting with all sorts of new space gods and wondrous new locations.
"And then we also see old King Thor, who's the last king of Asgard, thousands of years in the future, where something has gone horribly, horribly wrong."
Kieron Gillen and Greg Land were yesterday confirmed for a new Iron Man title.
Thor: God of Thunder will debut in November.
