The Milky Way sits in a cosmic neighborhood called the Local Group that includes more than 50 other galaxies. Those galaxies can be as small as a dwarf galaxy with up to only a few billion stars ...

Based on gravitational models that consider the influence of other celestial bodies in the Local Group of galaxies — specifically a number of dwarf galaxies orbiting the Milky Way ...

"However, we now find that the earlier prediction of a Milky Way-Andromeda collision is only one of several possibilities. Of course, the fate of the Local Group is not chaotic – with even ...

The speed of rotation varies with distance from the centre. The Milky Way is part of a group of galaxies known as the Local Group, which also includes the Andromeda Galaxy, the Triangulum Galaxy ...

What made the pulses puzzling to the astronomers was that they came in the form of both radio waves and X-rays. The discovery marks the first time that such objects, called long-period transients ...

The Milky Way and Andromeda are barreling toward each other at about 223,694 miles per hour (100 kilometers per second). However, the Local Group, or our corner of the universe, includes 100 known ...

Astronomers have long thought that the Milky Way is headed for an inevitable ... depends on the behavior of everything else in our Local Group, too: the panoply of at least 100 galaxies hanging ...

Thanks to that, simulations of the Local Group of galaxies can be made more accurate, and the future of the Milky Way can be worked out with more certainty. The study is published in Nature Astronomy.
