R Aquarii (R Aqr) is a variable star in the constellation Aquarius.
R Aquarii is a symbiotic star believed to contain a white dwarf and a Mira-type variable in a binary system.
The main Mira-type star is a red giant,
By its gravitational pull, the white dwarf draws in material from the red giant and occasionally ejects some of the surplus in weird loops to form the nebula
The whole system appears reddened because it is situated in a very dusty region of space, and its blue light is absorbed before reaching Earth.
The nebula around R Aquarii is also known as Cederblad 211.
It is possible that the nebula is the remnant of a nova-like outburst, which may have been observed by Japanese astronomers, in the year 930 AD.
It is reasonably bright but small and dominated by its central star. Visual observations are difficult and rare.
The central region of the jet shows an ejection that took place around 190 years ago, as well as
much younger structures.(WIKI)
