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

Our neighboring galaxy, Andromeda, is moving towards the Milky Way galaxy at an alarming rate of 110 kilometers per second. Scientists all over the world have always considered that there is a ...

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 ...

The Andromeda galaxy is surrounded by a constellation of dwarf galaxies that are arranged in a highly lopsided manner. Analysis of cosmological simulations published in Nature Astronomy reveal that ...

The embedded variable stars proved that the Andromeda nebula was much farther away than the stars that comprised the Milky Way. Andromeda was therefore a separate galaxy — similar to ...

But the satellites of the Milky Way and M31 show different evolutionary histories, and this new galaxy, dubbed Andromeda XXXV ...

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

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

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

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 ...
