Stargazers may catch a cosmic light show this Fourth of July weekend when the Milky Way appears in the night sky across the ...

The Milky Way's core will be visible this month and through August. Here's what Tennessee stargazers should know.

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 ...

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.

Previous research into the impending merger assumed that Andromeda’s transverse motion was small, making the potential for a Milky Way merger much higher. But the newest findings suggest otherwise.

Milky Way may be visible on July Fourth weekend across the U.S.: How to see our galaxy The center of our home galaxy, the Milky Way is composed of billions of stars that are expected to be bright ...

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.

If the Milky Way and Andromeda galaxies did collide, the merger would be strong enough to throw the sun into a new region in space, wrote NASA in 2012, when astronomers predicted this crash was a ...
