Cette impression d'artiste montre à quoi pourrait ressembler le système binaire VFTS 243 si nous l'observions de près. Le système, qui est situé dans la nébuleuse de la Tarentule dans le Grand Nuage de Magellan, est composé d'une étoile chaude et bleue avec 25 fois la masse du Soleil et d'un trou noir, qui contient au moins neuf fois la masse du Soleil. Les tailles des deux composants du système binaires ne sont pas à l'échelle : en réalité, l'étoile bleue est environ 200.000 fois plus grande que le trou noir. Notez que l'effet de « lentille » autour du trou noir est montré à des fins d'illustration uniquement, pour rendre cet objet sombre plus visible dans l'image. L'inclinaison du système fait qu'en le regardant depuis la Terre, on ne peut pas observer le trou noir éclipsant l'étoile. © L. Calcada, ESO
