A new composite image of the Andromeda Galaxy is offering an unprecedented view of our closest spiral galactic neighbor.

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 ...

The collision between the Milky Way and Andromeda, long considered inevitable, might ultimately not occur. Recent simulations challenge this prediction, opening new perspectives on our galaxy's fate.

The collision of the Milky Way and Andromeda galaxies that scientists believed was inevitable has a much lower probability than previously thought. The Associated Press reported Monday that ...

The Andromeda Galaxy, a spiral galaxy also known as Messier 31 or simply M31, is one of several galaxies, including the Milky Way, that comprise what is known as the Local Group. Astronomers have long ...

They explored how the Milky Way, Andromeda, and their significant satellite galaxies, like M33 and the Large Magellanic Cloud (LMC), interact gravitationally. Possible future MW-M31 orbits.
