Some of my current favourites include:
Atlas Obscura - they say "a guide to the world's strange, incredible and wondrous places" which is about right. A bit US - heavy but that's OK.
Sticky Notes - if classical music is your thing this is worth a listen. I really enjoy it.
13 Minutes to the Moon is an older series about the 1st moon landing with interviews with a load of the people involved, with a second series on Apollo 13. Fascinating, especially the first series.
If you are into Formula 1 then "Beyond the Grid" is very good.
