Hubble’s work pushed the field of astronomy forward, starting with his paper demonstrating that some objects exist outside our galaxy.
The universe is constantly expanding, but how do scientists think about what it’s expanding into?
In 1924, astronomer Edwin Hubble realised two objects were too distant to be inside our galaxy.
The Hubble tension has been described as a “crisis” for cosmology. Can it be resolved?
The darkness of the night sky seems so obvious as to need no explanation – yet it has intrigued and baffled scientists for centuries.
Thirty years ago the Hubble Space Telescope began snapping photos of distant stars, providing a time machine that has taken astronomers back to when the universe was less than a billion years old.
