The Sky At Night is moving to a new slot on BBC4 next year following a campaign by viewers to keep it on the air.
The show, first broadcast in 1957, will be shown on BBC4 in a monthly half-hour slot f rom February with repeats on BBC2.
No decisions have been made about the presenter's role which has been filled by a series of guest stars following the death of host Sir Patrick Moore last December aged 89.
Kim Shillinglaw, head of commissioning science and natural history, said: "Sir Patrick Moore inspired generations of astronomers and I hope that alongside the BBC's other astronomy content, such as BBC2's Stargazing Live, The Sky At Night will enthuse further generations about the wonder of the night sky."
More than 40,000 fans signed a petition in support of the show following reports that it could be axed.
Until his final illness, Sir Patrick missed only one episode in the show's history when he was struck down by food poisoning.
His trademark monocle, unique delivery and occasional performances on the xylophone made him a familiar target for satirists and impressionists, but his - and the show's - scientific credentials were never in doubt.
Guests have included prominent scientists as well as rock star Brian May, Goon Show star Michael Bentine and astronauts Neil Armstrong and Buzz Aldrin.
