Everything we know about Star Trek: Strange New Worlds Season 4

Space, as every Star Trek fan knows, is the final frontier – and Captain Christopher Pike is ready to explore the final frontier once again

After three acclaimed seasons filled with daring missions, memorable characters and plenty of classic Star Trek optimism, Star Trek: Strange New Worlds returns for a fourth outing that promises more action, discovery and impossible decisions among the stars.

The fourth season of Star Trek: Strange New Worlds premieres exclusively on Paramount+ (Apps > Paramount+) on Thursday 23 July.

Whether you've been following the U.S.S. Enterprise since the beginning or you're curious to see why Strange New Worlds has become one of the franchise's most popular modern series, here's everything you need to know before embarking on Season 4.

Set in the years before Captain James T. Kirk takes command of the U.S.S. Enterprise, Star Trek: Strange New Worlds follows Captain Christopher Pike and his crew as they travel across the galaxy on missions of exploration, diplomacy and first contact.

Unlike many modern sci-fi series that tell one long story across an entire season, Strange New Worlds embraces the spirit of classic Star Trek. Most episodes tell a self-contained story, introducing new worlds, scientific mysteries and moral dilemmas while continuing the characters’ longer-running emotional journeys.

It's a winning formula that has earned praise from longtime Trekkies and newcomers alike. One week the crew might find themselves in the middle of an intense space battle, while the next brings a mystery, a comedy adventure or a courtroom drama. That variety keeps every mission feeling fresh.

Of course, beneath the spectacular visual effects and thrilling action is the hopeful vision that has always defined Star Trek – a future where curiosity, compassion and cooperation are just as important as phasers and photon torpedoes.

Season 4 sees Captain Pike lead the U.S.S. Enterprise crew on another series of thrilling and emotional adventures across the stars.

Along the way, they will confront both personal struggles and external threats, meet colourful new characters, reunite with familiar faces and encounter terrifying aliens – all while holding on to Star Trek’s hopeful vision of the future.

The season also places a greater focus on the wider Enterprise crew, allowing fan-favourite characters and newer members of the team to take centre stage.

With the return of familiar faces such as Commander Pelia and James T. Kirk, alongside fresh challenges and unexpected encounters, Season 4 promises to deliver the mix of adventure, humour, heart and discovery that has become the hallmark of Strange New Worlds.

One of the biggest strengths of Strange New Worlds has always been its exceptional ensemble, and Season 4 sees many familiar faces back on the bridge.

Returning cast members include:

• Anson Mount as Captain Christopher Pike

• Ethan Peck as Spock

• Rebecca Romijn as Number One (Una Chin-Riley)

• Celia Rose Gooding as Nyota Uhura

• Jess Bush as Nurse Christine Chapel

• Babs Olusanmokun as Dr Joseph M'Benga

• Christina Chong as La'an Noonien-Singh

• Melissa Navia as Erica Ortegas

• Martin Quinn as Montgomery "Scotty" Scott

Season 4 will also feature recurring guest stars familiar to Star Trek: Strange New World fans: 

• Paul Wesley as James T. Kirk

• Carol Kane as Commander Pelia

Yes, you read that right: James T. Kirk is beaming back for Season 4. Paul Wesley, who first stepped into the boots of the iconic Starfleet captain in the Season 1 finale, "A Quality of Mercy," is officially set to reprise the role.

And he won't be flying solo. Carol Kane is also returning as Commander Pelia, bringing back the delightfully quirky engineer she introduced in the Season 2 premiere, "The Broken Circle."

One of the best things about Strange New Worlds is that you never quite know what’s coming next – and Season 4 keeps that winning formula firmly intact.

Expect a genre-hopping adventure that blends pulse-racing action, big sci-fi ideas, character-driven drama and the occasional light-hearted episode that lets the Enterprise crew show a different side of themselves.

At its heart, the series remains a celebration of discovery. Every mission brings the chance to explore unfamiliar worlds, encounter fascinating new cultures and tackle mind-bending mysteries where there are no easy answers.

The official trailer promises plenty of spectacle, from stunning visual effect, striking alien environments to large-scale space action. But it’s the quiet moments between Pike and the crew that continue to give the series its emotional pull.

That mix of blockbuster thrills, thought-provoking storytelling and genuinely likeable characters is exactly why Strange New Worlds has become such a hit with viewers.

The Season 4 trailer teases Pike leading his crew into uncharted territory, while Spock, Una, La’an, Uhura and the rest of the Enterprise team find themselves facing dangerous situations both on and off the ship.

With glimpses of strange new worlds, unexpected threats and the crew working together against the odds, Season 4 looks set to deliver another epic chapter filled with adventure, discovery and the spirit of exploration that defines Strange New Worlds.

Star Trek: Strange New Worlds Season 4 streams exclusively on Paramount+ (Apps > Paramount+) starting on Thursday 23 July. The 10-episode season rolls out new episodes weekly on Thursdays through the finale on Thursday 24 September.

If you have our Virgin TV 360 or Stream box, you can access Paramount+ alongside a huge range of other streaming apps from one place, making it easy to jump straight into the latest adventures aboard the U.S.S. Enterprise without switching devices.

Whether you're catching up from the very beginning or diving straight into the newest missions, everything is ready for your next voyage into the final frontier.
