You can help astronomers unlock the secrets of Jupiter!

As Futura explained in a previous article, the rise ofastronautics during the second half of the twentiethe century made it possible to transpose the models and techniques of geophysics and geochemistry to other planets in order to carry out comparative planetology and see how the other planets had evolved and had been structured under different …

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

A “dormant” black hole discovered for the first time outside our Galaxy

Black holes have become commonplace in the media landscape in recent years and despite the enigmas that still surround them and that touch on very deep questions of theoretical physics, they are commonly considered in astrophysics and in cosmology. We even study their emissions They propagate at the speed of light carrying energy. We can …
