Computer simulations carried out by astronomers from the University of Groningen in collaboration with researchers from Germany, France and Sweden show that most of the (dark) matter beyond the Local ...

Our Galaxy, Andromeda and their companion dwarf galaxies form the Local Group. Most of the mass in and around it is believed to be dark matter rather than gas or stars, so its distribution must be ...

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 ...

(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) ...

The Milky Way and Andromeda galaxies are trapped in a sheet of dark matter, a new study says. According to a team of scientists led by the University of Groningen, in the Netherlands, this ...

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 ...

Galaxies and clusters are the ensembles of stars and other astronomical objects bound together by gravitational forces. Galaxies are ordered into galaxy groups, which are in turn organised into ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. When will the Milky Way collide with the Andromeda Galaxy?

Using observations from Chile, astronomers have logged nearly 50 extremely faint dwarf systems — including so-called "ghost galaxies" — around three larger galaxies, adding new data to a major ...

\n \nVideo: H. Courtois, D. Pomarède; SDvision Local Map\nA map of the nearest galaxies to our own shows how they are clustered in the same plane, like the planets of our solar system. The galaxies ...

In this 2012 visualization, the Andromeda galaxy (left) appears in Earth's skies and begins to distort the Milky Way as the two galaxies merge. This hypothetical scenario was previously expected to ...
