Building on the triumph of its inaugural season, which garnered over 2.7 million streams on BBC iPlayer, Radio 1’s Sian Eleri is set to embark on a fresh exploration into the realm of the paranormal—specifically, UFOs.

Sian will scrutinise a series of peculiar occurrences marked as one of the most substantial compilations of UFO and extraterrestrial encounters in recorded history. Along the southern and western coasts of Wales during the 1970s and 1980s, numerous ordinary and unrelated individuals in towns, seaside resorts, and rural hamlets recounted a surge of enigmatic and harrowing sightings.

Sian Eleri says: “A second series is upon us! It’s been so eye-opening to investigate such open-ended issues, with series one raising questions challenging my own beliefs, so I can’t wait to get started on the next celestial adventure. The world of UFOs, extra-terrestrial activity and other theories around what exists in our skies is vast, so who knows what we might discover? I’m intrigued to find out.”

From locating eyewitnesses and dedicated researchers, who have devoted their lives to uncovering answers, to those suspecting a hoax or psychological phenomena, Sian will plumb every hypothesis in her pursuit of the truth.

In the footsteps of the maiden series, “Paranormal: The Girl, The Ghost and the Gravestone,” where Sian probed an ostensibly haunted farmhouse in North Wales, her innate scepticism will once again be put to the test.

Clare Sillery, Head of Documentary Commissioning for the BBC, says: “It’s been great to see how our audience enjoyed the first series of Paranormal. I’m delighted Sian Eleri will be returning – this time for a dive into the weird world of Ufology.”

Nick Andrews, Head of Commissioning at BBC Wales says: “Our nation’s obsession with all things paranormal is confirmed with our smash hit first series. Why wouldn’t we go again? This time to outer space and if some of the rumours are to be confirmed and the archive believed, Sian’s about to uncover an extraordinary true story…or is she? This is what we love about this series and BBC Cymru Wales is right behind (the sofa) as Sian and her team take us on another terrific adventure. You couldn’t make it up.”

The fourth instalment of the Paranormal series, comprising four episodes of 30 minutes each, is produced by Twenty Twenty Television for BBC Three, BBC One, and iPlayer. The commissioning was overseen by Fiona Campbell, Controller of Youth Audiences (BBC Three and BBC iPlayer), Clare Sillery, Head of Commissioning for Documentaries, and Nick Andrews, Head of Commissioning for BBC Wales. At Twenty Twenty, Ruth Kelly serves as the Director of Programmes, and Jo Hughes as the Executive Producer. Rory Jackson holds the post of Series Director, with Hannah Horan as Series Producer.
