You are about to listen to a BBC podcast and I'd like to tell you a bit about what goes into making one.

I'm Sadata Sese, an assistant commissioner of podcasts for BBC Sounds.

I pull a lot of levers to support a diverse range of podcasts on all sorts of subjects,

relationships, identity, comedy, even one that mixes poetry, music and inner city life.

So one day I'll be helping host develop their ideas, the next fact-checking, a feature,

and the next looking at how a podcast connects with its audience, and maybe that's you.

So if you like this podcast, check out some others on BBC Sounds.

Hello, curious-minded listeners.

This week's Inside Science comes to you on a dark, dark night in a dark, dark,

observatory.

We're bringing you a Halloweenlloween special from the glorious if

slightly drizzly jodrell bank in cheshire and i am here with resident space watcher and professor of

astrophysics tim oh brian hiya tim hello and the drip drip that we can hear is is actually the

noise of rain on the tin roof exactly it's very unusual to have this sort of weather here, I'm afraid.

Yeah, we can't see that much in the sky tonight, but we will get to that.

In a bit, we are going to be finding out about the celestial origins of Halloween and what you

might be able to see in the sky on this particularly dark night if it's not completely obliterated by rain clouds.

Also, on today's gruesome program, blood-sucking leeches, the horror of pumpkin waste,

and could zombies ever be real? No tricks here, just scientific treats.

Now, Tim, Halloween has its roots in an ancient Celtic tradition that I'm not all that

ophae with, but I understand it has some celestial origins too.
