Stars in distant galaxies are more massive than those in the Milky Way

A team of astrophysicists from the University of Copenhagen has achieved an important result by studying stellar populations in a large sample of galaxies far beyond the Milky Way. The discovery could change our understanding of a wide range of astronomical phenomena, such as those related to the formation of black holes, supernovae and the … Read more

A hidden graveyard of dead stars would envelop our galaxy

Simulations suggest that a significant number of neutron stars and stellar black holes born in the disc or bulge of our Milky Way Galaxy were ejected into orbits outside these structures. So there would be a hidden world of dead stars waiting to be discovered around our galaxy. The theory of the structure and evolution … Read more

Astronomers have found the original core of the Milky Way

Until today he was a suspect but had never been found. Our galaxy, the Milky Way, has a core of stars, among the very first it has ever hosted. And scientists have just proven its presence thanks to the latest data collected by the Gaia satellite! At the top of its 100,000 light-year diameter, our … Read more

A ‘glowing’ bubble of gas circles the Milky Way’s giant black hole at breakneck speed

On May 12, 2022, the very first image of the central black hole in our galaxy, Sagittarius A*, was revealed. Scientists have since continued their studies of this supermassive star. And by observing data from the Alma radio telescope, they made a surprising discovery: a bubble of glowing gas is orbiting the black hole at … Read more

The giant black hole at the center of our galaxy has erupted, and astronomers have seen it all!

While studying the supermassive black hole at the center of our galaxy, Sagittarius A*, scientists made a strange discovery: a bubble of glowing gas spinning around it at very high speed! A phenomenon that is explained by the eruption of black holes. On May 12, 2022, the very first image of our central black hole … Read more
