Pulsando o RS Puppis, a estrela mais brilhante no centro da imagem, é dez vezes mais massivo que o nosso Sol e, em média, 15.000 vezes mais luminoso.
De fato, o RS Pup é uma estrela variável Cefeida, uma classe de estrelas cujo brilho é usado para estimar as distâncias de galáxias próximas como um dos primeiros passos no estabelecimento da escala de distância cósmica. Como RS Pup pulsa ao longo de um período de cerca de 40 dias, suas mudanças regulares no brilho também são vistas ao longo de sua nebulosa em torno atrasado no tempo, efetivamente um eco de luz.
Usando medições do tempo de atraso e tamanho angular da nebulosa, a velocidade conhecida da luz permite que os astrônomos determinem geometricamente a distância do filhote RS a 6.500 anos-luz, com um erro notavelmente pequeno de mais ou menos 90 anos-luz.
Uma conquista impressionante para a astronomia estelar, a distância medida pelo eco também estabelece com mais precisão o verdadeiro brilho do RS Pup e, por extensão, outras estrelas Cefeidas, melhorando o conhecimento das distâncias das galáxias além da Via Láctea.
