One of this summer's most anticipated summertime event series is Extant, the Steven Spielberg-produced sci-fi thriller starring Halle Berry as an astronaut who returns to Earth after spending a year in space, making a shocking discovery when she returns.

In this just-released teaser trailer for the series, Halle's character discovers she's pregnant — and what's growing inside her may not be entirely human.

Extant premieres Wednesday, July 9 on Global.
