How did a Cepheid variable star help Edwin Hubble prove the Andromeda Nebula was a galaxy? Roger BradySan Quentin, California ...

And with that beginning came an ancient, renewed question: if there was a starting point, who or what started it?This ...

A hundred years ago, astronomer Edwin Hubble revealed a universe of galaxies that existed beyond ours. His influence in astronomy continues to this day.

This study has the potential to help scientists better understand the long-term evolution, and ultimately, the fate of the universe. For the study, the researchers used NASA’s James Webb Space ...

A century ago, Edwin Hubble revolutionized our understanding of the universe by proving that the Milky Way is just one of many galaxies in an ever-expanding cosmos. This breakthrough led to the ...

Vivian Poulin asks if the tension between a direct measurement of the Hubble constant and constraints from the early universe could be resolved by new physics.

It seemed that these redshifted galaxies were all moving away from the Milky Way. Hubble’s results suggested the farther away a galaxy was, the faster it was moving away from Earth.

Hubble’s work pushed the field of astronomy forward, starting with his paper demonstrating that some objects exist outside our galaxy.

Two years prior to Hubble publishing his findings, the Belgian physicist and Jesuit priest Georges Lemaître analyzed the Hubble and Slifer observations and first came to the conclusion of an expanding ...
