The Milky Way is not crossing another galaxy in the traditional sense. Galaxies are massive and move incredibly slowly. Instead of "crossing," galaxies interact and sometimes even collide over vast spans of time.

Here's the breakdown:

* Milky Way and Andromeda: The Milky Way is on a collision course with the Andromeda Galaxy. This event is expected to happen in about 4 billion years, and it will be a dramatic and long-lasting process.

* Other Interactions: The Milky Way also interacts with smaller galaxies like the Magellanic Clouds, which are orbiting it. These interactions can cause gravitational disturbances and even stripping of material.

* No Immediate Crossing: There's no other galaxy that the Milky Way is currently "crossing" in the sense of a short-term, dramatic event.

So, while the Milky Way is not currently crossing another galaxy, it is involved in ongoing and future interactions that will shape its evolution.
