The four-part documentary series will see Walsh travel across Britain, Europe and America in search of answers to one enormous question: Are we really alone?

Bradley Walsh: Out of This World will premiere on Sky HISTORY on Tuesday 3 November.

In the new series, he will investigate some of the greatest mysteries of our skies, on our land and beneath our seas, all with his trademark humour, curiosity and willingness to ask the questions the rest of us are thinking.

According to the series synopsis: "From UFOs and USOs to Atlantis, Stonehenge and crop circles, Bradley approaches the unexplained with an open mind, a healthy dose of scepticism and plenty of laughs. It’s a global adventure like no other."

Walsh's journey begins with UFOs, delving into Britain's declassified Ministry of Defence files, before going on to explore the infamous Rendlesham Forest and then heading to Arizona to meet witnesses of the Phoenix Lights.

From there, he will round things off by entering the mysterious world of military UAP encounters, tackling the enduring legend of Atlantis in Spain and scrutinising who exactly built Stonehenge.

Bradley Walsh began his career as a professional footballer for Wormley Rovers before turning to the entertainment industry in the 1980s. As an actor he is recognised from Coronation Street, The Sarah Jane Adventures, and Law & Order: UK.

In 2018 he joined the cast of Doctor Who alongside Jodie Whittaker and played the role of Graham O'Brien for two seasons. More recently he is most well known as the presenter of The Chase and Gladiators.
