NICER(Neutron Star Interior Composition Explorer)の略称で呼ばれ記録されたものです。
CNN - The streaks of light in NASA's latest image look like air traffic routes, but it's a different way of looking at the entire sky. The arcs are actually tracing X-rays, recorded by the Neutron star Interior Composition Explorer, known as NICER.
NICER acts as a detector of cosmic sources from the International Space Station, which orbits the Earth every 93 minutes. NICER keeps tracking those sources, even at night.
This map of our sky represents the first 22 months of NICER's work, taking data from its nighttime observations. The arcs follow X-rays and energetic particle strikes. The most traveled pathways tracked by NICER reveal the brightest and most prominent arcs.
