Nearly 400 years ago, Galileo looked at the Pleiades star cluster through his telescope and noticed that the seven or so ...

The universe is constantly expanding, but when it comes to our cosmic neighborhood, two galaxies—our Milky Way and the Andromeda galaxy—are heading toward an inevitable collision. Andromeda, located 2 ...

While the Triangulum galaxy’s gravitational influence conspired to bring the Milky Way and Andromeda together, the LMC had a repellent effect. And when all four danced together, the odds of an ...

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 ...

By carefully considering uncertainties in current measurements and including the gravitational effects of nearby galaxies (the Large Magellanic Cloud, which is a massive satellite galaxy currently ...

Scientists previously predicted the pair of galaxies would merge in about five billion years. Now, research suggests that ...

Thank goodness for scientists and math. It turns out, we don't have to worry, maybe, about our galaxy colliding with a neighbor.

Andromeda may not collide with our galaxy, a new study suggests The Andromeda galaxy, about 2.5 million light-years away, moves fast. At 110 kilometres per second, it heads towards our Milky Way.

The Milky Way and the neighboring Andromeda galaxy are currently hurtling through space toward each other at a speed of about 250,000 miles per hour (400,000 kph), setting up a possible future ...

We also included two additional galaxies that influence the future paths of the Milky Way and Andromeda: the Large Magellanic Cloud, a massive satellite galaxy currently falling into the Milky Way, ...
