For years, astronomers have observed the strange motion of Andromeda, the Milky Way’s closest large galactic neighbor. While most galaxies in the universe are receding due to the expansion of space, ...

At a distance of 2.5 million light years from the Milky Way, it’s hard to believe that Andromeda is our closest neighbouring galaxy. But despite the huge distance between these two elliptical entities ...

Add Yahoo as a preferred source to see more of our stories on Google. For decades, astronomers have predicted that the Milky Way will eventually collide with its nearest large galactic neighbor, ...

A new ultra-faint dwarf galaxy has been discovered in the vicinity of Andromeda (M31), the Milky Way's large neighboring galaxy. The new study, published in Astronomy & Astrophysics suggests that the ...

The Andromeda Galaxy, or M31, isn’t just a great-looking spiral galaxy. It’s also the closest to us, which makes it visible to the naked eye from here on Earth. But the fact it’s (well, relatively) so ...

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 ...

Scientists suspect a black hole lurks at the center of most galaxies. The Milky Way’s black hole is called Sagittarius A*. (A* is scientist-code for “A-star.”) Its gravity, or attractive force, is so ...

The northern sky’s greatest galaxy gets its familiar name from the northern constellation where it resides, Andromeda the Princess. This star system is our nearest large spiral galaxy, and it sits at ...

Andromeda is a constellation based on the Ethiopian princess Andromeda from Greek mythology. It is located between Cassiopeia ...

Add Yahoo as a preferred source to see more of our stories on Google. This illustration shows a possible view from Earth of the early stages of a predicted merger billions of years from now between ...

The Milky Way and Andromeda have appeared locked on a destructive course for decades. Now, thousands of simulations suggest their collision is not destiny, but a contest between gravity, uncertain ...
