In this Sky at Night special, the team talk to Dr Nicola Fox, NASA's head of science, whose life began in the UK. Presenter Chris Lintott chats to Nicky about her early years growing up in Hitchin in Hertfordshire and discovers how she fell in love with the stars. Maggie Aderin-Pocock takes Nicky on a trip down memory lane. Both women studied physics at Imperial College London from the late 80s to early 90s. As they revisit familiar haunts, they discuss their experiences, and Maggie finds out about Nicky's love of astrophysics, the challenges she overcame and how she landed a dream job at NASA. 

Get ready for The Sky at Night's annual Question Time Special, where viewers get the opportunity to ask the questions they have always wanted answered about our universe.  Join host Dallas Campbell as he leads a panel of experts through a range of fascinating topics.

Regular presenters Maggie Aderin-Pocock, Chris Lintott and George Dransfield are joined by Prof Raman Prinja from University College London and Dr Heloise Stevance from Oxford University. Resident astronomer Pete Lawrence also makes an appearance, sharing a guide to the stars for the coming months and posing an intriguing question of his own.

This year's discussion covers subjects such as the nature of the oldest galaxies – what we're seeing and how we know they're so ancient. We delve into the search for habitable Earth-like planets and the effects of the stars they orbit. And we explore what might happen to Earth and our planetary neighbours when our sun begins the end of its life in billions of years' time.
