This video features five frames spanning from 2014 to 2023 of R Aquarii, a symbiotic binary star that lies only roughly 1,000 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 can also be seen to be spiralling outwards due to their interaction with material previously ejected by the binary.
This time-lapse highlights the value of Hubble’s high resolution optical observations in the changing Universe, known as time-domain astronomy.

As we approach solar maximum, the Sun is reaching new levels of activity for Solar Cycle 25. The Sunspot number has consistently exceeded predictions of the cycle with 2024 especially being way above what was predicted. That means we have been consistently seeing large numbers of active regions across the disk throughout the entire year. While this doesnt always mean large flares all the time, we have had periods (such as early May) where the Sun has produced some major flares. The last few months of 2024 are shaping up to continue this trend and we hope to continue to capture exciting solar data with XRT.
Hinode is a Japanese mission developed and launched by ISAS/JAXA, with NAOJ as domestic partner and NASA and STFC (UK) as international partners. It is operated by these agencies in co-operation with ESA and the NSC (Norway). The XRT instrument team is comprised of SAO, NASA, JAXA, and NAOJ.
