Season 2 of Star Trek: Discovery had the crew facing a mysterious and dangerous new threat tied to a series of puzzling signals scattered across the galaxy. Captain Christopher Pike of the USS Enterprise temporarily takes command of the Discovery after a distress call and leads the investigation into these "red bursts." Also during this season, Saru and the Kelpien species go through a life-changing transformation, we're introduced to a younger Spock, a return to Talos IV, and presented by a threatening AI presence. All of this makes for an exciting sophomore season of Star Trek's first streaming series.
