Galaxies

With more than 100 billion galaxies in the observable universe, the exciting discoveries and unanswered questions are endless. We bring you all the latest galaxy news, including reports on galaxy formation and stunning galactic photos. Each galaxy is unique, ranging from peculiar galaxies, morphed from tidal interactions, to the vast and breathtakingly beautiful spiral galaxies imaged in so many galaxy pictures. We will update you on the latest from our near neighbors, the Large and Small Magellanic Clouds, as well as the most distant galaxies viewed in the Hubble Ultra Deep Field.

Astronomers have used the Hubble Space Telescope to peer deep into the history of the universe, mapping galaxy formation by first examining distant quasars —supermassive black holes at the centers of galaxies which are rapidly accreting material and shining brightly — in the early universe. We’re continuing to learn how galaxies form, evolve, and shape the beloved universe we call home.

Disentangling the History of the Magellanic Clouds

The Magellanic Clouds — two nearby dwarf galaxies easily visible to the naked eye in the southern hemisphere — are key to understanding the dynamics and evolution of the Local Group of galaxies. Can an in-depth look at these galaxies’ outer regions help us make sense of their complicated interaction history?

Hubble’s View of Little Blue Dots

The recent discovery of a new type of tiny, star-forming galaxy is the latest in a zoo of detections shedding light on our early universe. What can we learn from the unique “little blue dots” found in archival Hubble data?

Globular Clusters for Faint Galaxies

The origin of ultra-diffuse galaxies (UDGs) has posed a long-standing mystery for astronomers. New observations of several of these faint giants with the Hubble Space Telescope are now lending support to one theory.
