Science history: Edwin Hubble uncovers the vastness of the universe with discovery of 'standard candle' — Oct. 5, 1923

On the night of Oct. 5, 1923, Edwin Hubble observed a strange star that flickered in intensity at regular intervals. The star, dubbed M31-V1, was key to showing that the universe extended far beyond the borders of the Milky Way.

Astronomers thought the Milky Way was doomed to crash into Andromeda. Now they’re not so sure

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 Milky Way may not collide with neighboring galaxy Andromeda after all: 'From near-certainty to a coin flip'

A collision between the Milky Way and neighboring galaxy Andromeda is far from a sure thing; in fact, it could hinge on the flip of a cosmic coin.

'This doesn't appear in computer simulations': Hubble maps chaotic history of Andromeda galaxy, and it's nothing like scientists expected

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.

One large Milky Way galaxy or many galaxies? 100 years ago, a young Edwin Hubble settled astronomy’s ‘Great Debate’

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…
