This Glowing Orb Is a Chemistry Experiment Aboard the ISS

It may look like someone's captured a baby sun, but this is actually a Russian chemistry experiment taking place on the International Space Station.

In fact, astronauts are testing how polymers -- repeated molecules that form long chains and are the basis for many common materials -- can be formed in space. In particular, the experiments aim to show if weightlessness can be used to create polymer walls that form shells. [ESA]
