The Andromeda galaxy's satellite galaxies exhibit a highly asymmetrical distribution, with over 80% concentrated on one side, challenging the standard cosmological model.

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 ...

Then, they pieced together a record of the X-ray light produced by a supermassive black hole in the Andromeda galaxy called M31 star or M31*. Their research provides insight into the unique ...

First up is the Andromeda Galaxy, our closest neighbour in the cosmos, featuring stunning spiral arms and a vibrant central core. Next is the Whirlpool Galaxy, a breathtaking spiral with a ...

Be careful out there, astronomers: There could be a dark galaxy in our midst. In research published today in Science Advances, researchers from the Chinese National Academy of Sciences discovered ...

A team has revealed new insights into the motion of massive stars in the Small Magellanic Cloud (SMC), a small galaxy neighboring the Milky Way. Their findings suggest that the gravitational pull ...

The team behind this discovery speculates that this gas could eventually become the hot, diffuse gas called the intracluster medium (ICM) that has been seen filling mature galaxy clusters.

The total value of an artist’s artworks sold at auction over a specific period. This metric reflects the artist’s overall market activity and demand in monetary terms. The middle value of all realized ...
