Andromeda XXXV is only about 20,000 times more massive than our Sun—very small, even for a satellite galaxy. For comparison, ...

The spiral galaxy 2MASX J23453268−0449256 is located nearly 1 billion light-years away from Earth, and measures about three ...

Astronomers at the University of Michigan have discovered a new satellite of the Andromeda Galaxy (M31), the Milky Way's ...

An curved arrow pointing right. In 3.75 billion years, Earth's Milky Way Galaxy will collide with the Andromeda Galaxy. Over the next several billion years, the two galaxies will rip each other ...

The findings reveal unusual chemical signatures and offer new insights into the behavior of novas beyond the Milky Way.

An ambitious new survey by the Hubble Space Telescope offers the first bird's-eye view of all known dwarf galaxies orbiting ...

Situated approximately 2.5 million light-years from Earth, the Andromeda Galaxy is the closest major galaxy to the Milky Way, belonging to the Local Group cluster. It is a barred spiral galaxy ...

Astronomers suspect Andromeda had a major collision with another galaxy relatively recently, perhaps 2 to 5 billion years ago. The Milky Way, on the other hand, probably hasn't had a run-in with ...

This offers forensic clues as to how our Milky Way galaxy and Andromeda have evolved differently over billions of years. Our Milky Way has been relatively placid. But it looks like Andromeda has ...

Andromeda: Closest key to Milky Way Since Hubble’s launch, astronomers have discovered over 1 trillion galaxies, but Andromeda stands out as the closest and most significant to our Milky Way.

NASA's Hubble Space Telescope has spotted some strange behaviour from a swarm of galaxies around Andromeda, our neighbour galaxy. A mere 2.5 million light years away from our Milky Way galaxy, NASA ...

The Andromeda galaxy, seen here by ... like a game of bumper cars — compared with the relatively placid evolution of the galaxies circling the Milky Way. The findings, published in The ...
