The music: As it’s December, OAE performs one of Bach’s Christmas cantatas, this one written for the Feast of John the Evangelist and first performed on December 27, 1723. It’s a sturdy, muscular work, with sackbuts (baroque trombones) doubling the vocal lines.

The science: The orchestra is joined by Maggie Aderin-Pocock, the presenter of the BBC’s legendary The Sky at Night series since 2014. With an extensive career in building satellites, Maggie tells us about the challenges of engineering for space.
