Poyasnenie: Issledovatel' vnutrennego stroeniya neitronnyh zvezd (Neutron star Interior Composition Explorer – NICER) nahoditsya na bortu Mezhdunarodnoi kosmicheskoi stancii. On povorachivaetsya i naklonyaetsya, chtoby sledit' za kosmicheskimi istochnikami rentgenovskogo izlucheniya, v to vremya kak stanciya sovershaet oborot vokrug planety Zemlya kazhdye 93 minuty. Rentgenovskie detektory vklyuchayutsya, kogda orbita stancii prohodit po nochnoi storone. Yarkie dugi i petli na etoi karte vsego neba pokazyvayut, kak NICER perevodilsya ot odnoi celi k drugoi v techenie 22 mesyacev raboty. Dugi shodyatsya k yarkim pyatnam – pul'saram na rentgenovskom nebe, kotorye NICER regulyarno nablyudaet. Pul'sary – eto vrashayushiesya neitronnye zvezdy, izluchayushie regulyarnye impul'sy rentgenovskih luchei. Promezhutki vremeni mezhdu impul'sami nastol'ko postoyanny, chto ih mozhno ispol'zovat' dlya navigacii – opredeleniya skorosti i polozheniya kosmicheskogo apparata. Eta rentgenovskaya karta vsego neba ot NICER postroena tak, chto nebesnyi ekvator prohodit gorizontal'no cherez centr.
