American astronomer Edwin Hubble (after whom the Hubble Space Telescope is named) coined the term “Local Group” for the galaxies he had identified as moving through space with the Milky Way. The term ...

Cosmic expansion allows distant galaxies to move away faster than light, while still letting us see ancient light they ...

(A) Dark matter distribution in our neighborhood in the Universe, the so-called Local Group of galaxies. The two large dark matter halos correspond to those of the Milky Way and Andromeda galaxy; (B) ...

Satellite galaxies are low-mass companions bound to more massive host galaxies within a common dark matter halo. In the Local Group—dominated by the Milky Way and Andromeda—these satellites exhibit a ...

Two new studies have measured the expansion of the universe in our immediate cosmic neighborhood using a novel method that analyzes the motion of two nearby galaxy groups within their surrounding ...

A cosmic dance could be the future of the Milky Way as it tracks a course to collide with neighboring galaxies, a University of Queensland survey has found. The paper is published in the Monthly ...

A high-resolution colour image showing the central galaxies NGC5713 and NGC5719 taken by the Hyper Suprime-Cam at the Subaru telescope in Hawaii. A cosmic dance could be the future of the Milky Way as ...
