The Sky In X-Ray

NASA is building up a map of the entire sky seen in X-rays, line by line with its NICER experiment.

In this image, numerous sweeping arcs seem to congregate at various bright regions. You may wonder: What is being shown? Air traffic routes? Information moving around the global internet? Magnetic fields looping across active areas on the Sun?

In fact, this is a map of the entire sky in X-rays recorded by NASA's Neutron star Interior Composition Explorer (NICER), a payload on the International Space Station.
