Wow! That was our reaction to seeing this picture (and others) of a light show aboard the International Space Station. After confirming with NASA that the images circulating lately on social media are real, we were directed to the Japan Aerospace Exploration Agency (JAXA), who co-ordinated this experiment.
The project, JAXA added, is “designed to produce aurora-like luminescence traces using a spinning top with both linear and point light sources. In microgravity, the center of gravity of the spinning top continuously and randomly moves while it is spinning. Using the characteristics of the top in microgravity, the project tries to produce various light arts using its unexpected movements/spins, by changing attaching locations of its arms and weights.”
Takuro Osaka, a professor at the University of Tsukuba, was the principal investigator of this art project. What are your favorite experiments performed by astronauts in space? Let us know in the comments.
