Learn about the new research that changes the estimates of the Milky Way’s demise.

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

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 ...

These companion galaxies exert gravitational tugs that change the motions of their hosts. M33 nudges Andromeda slightly toward the Milky Way, increasing the chance of a merger.

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.

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.
