Astronomers have long thought that the Milky Way is headed for an inevitable crash with its neighbor, Andromeda. But a new study complicates the story.

Astronomers have long believed that our Milky Way will eventually collide with the Andromeda galaxy. A new study suggests that we might escape that fate. The spiral Andromeda galaxy is our closest ...

Students from Western University are in northern Ontario this week to launch an infrared camera the size of the tennis ball into the Earth’s stratosphere.

Earlier studies have claimed to find evidence of extragalactic planets in the Andromeda galaxy. Other astronomers were skeptical about these detections, too.

Astronomers used the motion of stars to reconstruct a galactic collision that happened 2 billion years ago at the nearest neighboring large galaxy.

Because it is set in a brand new galaxy, Andromeda will feature plenty of new planets to explore. The several we have already seen are diverse and beautiful to behold.

Galaxy groups and clusters, in turn, often belong to vast superclusters measuring hundreds of millions of light years in diameter. Before our minds start to reel at these scales, let's return to the ...

Many of the planets in the Andromeda galaxy are uninhabitable, and along with these new dangerous environments, the protagonist Ryder and their crew are thrust into the midst of a war between the ...
