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

The Milky Way has a 50-50 chance of colliding with a nearby galaxy in the next 10 billion years, a new study finds. Yet while those odds appear daunting, the new finding suggests the catastrophic ...

But the satellites of the Milky Way and M31 show different evolutionary histories, and this new galaxy, dubbed Andromeda XXXV, is no exception. The question of why Milky Way satellites appear so ...

Clearly, the Andromeda Nebula was a system of stars quite separate from the Milky Way, and in many ways comparable to it. From this simple observation, soon repeated for other starry nebulae ...

"A supercomputer simulation shows many galaxies merging over time. The parts of galaxies we can see are glowing stars forming ...

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

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 ...

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 ...

Graduate students from the Graduate University for Advanced Studies (SOKENDAI) participated in an observational training ...

Astronomers at the University of Michigan have discovered a new satellite of the Andromeda Galaxy (M31), the Milky Way’s closest major galactic neighbor, and it has broken the record for the ...

Astronomers have discovered Andromeda XXXV, the smallest and faintest known galaxy, located 3 million light-years away. It challenges existing models of galaxy formation, as similar small galaxies ...
