The CW's new alien drama, Roswell, New Mexico, takes viewers on an out of this world journey through the lives of the aliens and humans living in the world's capital for all things extraterrestrial — and it does it while sporting some swoon-worthy romances too!

Nathan Dean Parsons plays Max, one of three surviving aliens of the 1947 Roswell UFO crash who are just trying to live their lives and keep their alien abilities secret in a small Southern town. It's easier said than done, especially when Max's high school crush, Liz (Jeanine Mason), returns home and quickly discovers he's not your average police officer. But is he a friendly visitor from another planet or a murderous invader?

While Mason's on-screen counterpart might be in the dark about all things alien, the stars of Roswell, New Mexico are anything but. TV Guide put Parsons and Mason to the test to see how many pop culture aliens they could identify, and they actually did a pretty stellar job. From Daleks and E.T. to Supergirl, these two proved they've done their homework when it comes to on-screen extraterrestrials.

Roswell, New Mexico premieres Tuesday, Jan. 15 at 9/8c on The CW.
