The Latest Breaking News from Andromeda

Andromeda never looked as good as it does in a new image from the Chandra X-ray observatory and a range of powerful telescopes. A fitting tribute to dark matter pioneer Vera Rubin.

For years, astronomers have predicted a dramatic fate for our galaxy: a head-on collision with Andromeda, our nearest large galactic neighbour. This merger – expected in about 5 billion years – has become a staple of astronomy documentaries, textbooks and popular science writing.

The Andromeda galaxy's family of satellite galaxies point towards the Milky Way, and nobody knows why.

Astronomers have discovered the smallest dwarf galaxy ever seen. It is a mystery how the satellite galaxy of Andromeda survived the blistering conditions of the early universe.

An ambitious new survey by the Hubble Space Telescope offers the first bird's-eye view of all known dwarf galaxies orbiting the Andromeda galaxy. The data suggests Andromeda had a chaotic past unlike anything scientists expected.

A family portrait of the Andromeda galaxy and its orbiting dwarf satellites raises questions about how galaxies evolve.

A hundred years ago, astronomer Edwin Hubble dramatically expanded the size of the known universe. At a meeting of the American Astronomical Society in January 1925, a paper read by one of his colleagues on his behalf reported that the Andromeda nebula, also called M31, was nearly a million light…

The most detailed panorama of the entire Andromeda galaxy is packed with science that could revolutionize our understanding of how spiral galaxies across the universe form and evolve.

The new composite image, which combines hundreds of photos from the Hubble Space Telescope, shows the Andromeda Galaxy with more than 200 million individually resolved stars.
