She will join existing presenter astrophysicist Dr Chris Lintott when the series returns in its new half-hour slot on BBC Four in February.
Dr Aderin-Pocock is a research fellow at the University College London Department of Science and Technology Studies and an honorary research associate in the Physics and Astronomy Department. Her TV career includes presenting BBC Two's Do We Really Need The Moon? and Do We Really Need Satellites? as well as regular appearances on BBC One's The One Show.
It was feared the long-running astronomy series - which began in April 1957 - would be axed after the death of its host Sir Patrick Moore last December, but it was reprieved after a massive campaign.
Commenting on her new role, she said:
As a child I would beg my parents to allow me to stay up late and watch the programme. It even inspired me to go to night school at a young age to make my own telescope mirror, which I lovingly crafted and gave me my first glimpse of the breathtaking spectacle above us.
This enthusiasm eventually led to a degree in physics and a PhD in mechanical engineering and then working on the wonderful 8m Gemini telescope in Chile. I'm so looking forward to being a part of this cherished and much-loved institution.
Over the past year, it has been fronted by a team of regular reporter/presenters, who will continue to appear in the future.
