Does anyone know the background music used in Image FM's Bigyan Ka Kura hosted by Grishma Bhandari?

I'm trying to identify the background music that used to play during the radio program "Bigyan Ka Kura" hosted by Grishma Bhandari on Image FM. The music would play softly while she was speaking, not just during the intro or outro.

I've had that tune stuck in my head for years but have never been able to find its name. It had a calm, scientific/documentary-style instrumental feel.
