Hubble: Evolution of R Aquarii from 2014-2023 (Timelapse)

This video features five frames spanning from 2014 to 2023 of R Aquarii, a symbiotic binary star that lies approximately 700 light-years from Earth in the constellation Aquarius. This is a type of binary star system consisting of a white dwarf and a red giant that is surrounded by a large, dynamic nebula. These frames show the brightness of the central binary changing over time due to strong pulsations in the red giant star. The central structures spiral outward due to their interaction with material previously ejected by the binary. This timelapse highlights the value of Hubble's high resolution optical observations in the changing universe, known as time-domain astronomy.
