Earth and our entire Milky Way galaxy may sit inside a mysterious giant hole which makes the cosmos expand faster here than in neighboring regions of the universe, astronomers say.

Particular stars called Cepheid variables allow astronomers to determine distance, and Hubble spotted one of these within M31 ...

Our universe is expanding and that inflation can be measured both optically and via microwaves. In the 1920s, Edwin Hubble observed a surprising discovery that galaxies accelerate as they move ...
