Galáxias são diferentes do que se pensava?

Quando imaginamos galáxias, é fácil imaginar que as estrelas em suas bordas marcam os limites entre aglomerado e vasto espaço profundo.

Mas, uma pesquisa recente revela que esses aglomerados são muito maiores que os nossos olhos podem perceber.

Elas são envoltas por gases, compondo o meio circungaláctico.

E esses circungalácticos podem se estender bem além dos limites observáveis.

Na pesquisa da galáxia IRAS 08339+6517, foi descoberto que embora o aglomerado estelar tenha cerca de 7,8 mil anos-luz de extensão.

Seu meio circungaláctico se prolonga por até 100 mil anos-luz.
