The monthly BBC One astronomy series could be dropped following the death of its original host Sir Patrick Moore, claims The Daily Mail.
The tabloid quotes a BBC spokesman as saying: "The Sky at Night is on air until the end of the year. Plans for subsequent series are being discussed."
Moore began presenting the show in 1957, with his final episode airing in January 2013, following his death in December 2012.
Chris Lintott and Lucie Green have hosted the programme since February 2013.
A fan petition campaigning for the The Sky at Night to continue has now reached over 1,500 signatures, with the Change.org post reading: "The BBC is a Public Service Broadcasting organisation and no programme could be as well described as being a Public Service as The Sky At Night."
