Astronomers discover that a galaxy orbiting the Milky Way is home to a supermassive black hole

Published: 5 dic 2021 05:54 GMT According to the researchers, this is the second closest known supermassive black hole after the one at the center of our galaxy. Astronomers have recently discovered that a small satellite galaxy orbiting the Milky Way is home to an unusually massive black hole. According to a study published in … Read more

Scientists discover the first ‘plume’ in the Milky Way

The scientists further found that the Gangotri Wave is not as straight as expected, but zigzags back and forth along its length in a pattern similar to a sine wave. At the moment, it has not been possible to explain the strange phenomenon, but the researchers suppose that some force not yet identified could be … Read more

First filament that joins two spiral arms of the Milky Way

MADRID, 29 Nov. (EUROPA PRESS) – A long, thin filament of cold, dense gas extends from the galactic center, connecting two of the spiral arms of the Milky Way, the first observed of its kind. As reported by astronomers in Astrophysical Journal Letters, this is the first time that such a structure has been detected … Read more

The Milky Way loses a lot of satellite galaxies

A new study reveals that the Milky Way contains significantly fewer galaxies in its orbit than previously thought. A new investigation of the data collected by the Gaia space probe (Global Astrometric Interferometer for Astrophysics), has revealed that most of the galaxies are relatively new in the region, clarifying that they are too young to … Read more
