About this work
A NICER team member measures the focused optical power of each X-ray concentrator in a clean tent at NASA’s Goddard Space Flight Center. The Neutron star Interior Composition Explorer (NICER) is a NASA Explorer Mission of Opportunity dedicated to studying the extraordinary environments — strong gravity, ultra-dense matter, and the most powerful magnetic fields in the universe — embodied by neutron stars.
