China's Chang'e-3 mission landed on the moon in December 2013 and deployed a lunar rover known as Yutu or Jade Rabbit;
it also carried a robotic telescope designed to observe various celestial objects such as galaxies, active galactic nuclei,
variable stars, binaries, novae, quasars and blazars in the near-ultraviolet band. The Lunar-based Ultraviolet Telescope
(LUT) was recently used by a team of Chinese astronomers to observe a peculiar binary star designated V921 Her. Results of
these observations are described in a paper published Aug. 1 on arXiv.org.
