The team found only a 2 percent probability that the galaxies will collide in the next five billion years. In slightly over half of the simulated scenarios, Andromeda and the Milky Way experience at ...

Our Milky Way galaxy is a cannibal. You might wonder what would happen if our disk-shaped spiral galaxy were to one day collide with Andromeda, which is over twice the size of the Milky Way.

Astronomers know that mergers play a huge role in galaxy growth. Right now, the Milky Way is slowly consuming the Large and ...

This illustration shows the location of the 43 quasars scientists used to probe Andromeda's gaseous halo. Quasars are extremely distant, brilliant cores of galaxies powered by star-eating black holes.

It turns out that looming collision between our Milky Way and Andromeda galaxies might not happen after all. Astronomers reported Monday that the probability of the two spiral galaxies colliding is ...

For years, astronomers have believed that the fate of the Milky Way was tied to our largest neighboring galaxy, the Andromeda galaxy. However, a new study now says that this future Milky Way merger ...

An illustration of the predicted merger between the Milky Way and Andromeda. NASA; ESA; Z. Levay and R. van der Marel, STScI; T. Hallas; and A. Mellinger For decades, astronomers have predicted that, ...

For years, astronomers have predicted a dramatic fate for our galaxy: a head-on collision with Andromeda, our nearest large galactic neighbor. This merger—expected in about 5 billion years—has become ...

Modern astrophysics tells us that the universe is expanding. Everything is getting farther apart as space-time stretches outward into nothingness. Well, almost everything. Scientists have long ...
