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 ...

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 ...

Studies of our own galaxy's growth imply it has been a rather placid place with no major mergers with medium or large galaxies in the past 10 billion years at least, whereas the Andromeda galaxy ...

A Michigan State University researcher saw X-rays coming from a black hole using the NASA Chandra X-Ray Observatory telescope ...

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 ...

By that point, the Milky Way and Andromeda galaxies - two, separate spiral galaxies - will be no more. Our solar system will have a new home in an entirely different class of galaxy, called an ...

Andromeda XXXV contains an estimated 20,000 Suns worth of stars and lies about half a million light-years from the center of the Andromeda Galaxy, or about three times the width of M31 itself.

Some were clearly groups of many stars, but in 1907 there was no way to say how far away ... Today, astronomers have measured the distance to the Andromeda Galaxy much more precisely; they find ...
