With more than 100 billion galaxies in the observable universe, the exciting discoveries and unanswered questions are endless. We bring you the latest news in galaxies and galaxy formation. 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.

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.

Teacup Galaxy

Tempest in the Teacup Galaxy

New observations of the Teacup Galaxy show that even black holes with wimpy radio jets can quench a galaxy's star formation. An unassuming nearby galaxy nicknamed The Teacup (more formally known as J1430+1339) hides a tempest inside. The supermassive black hole at this galaxy's center is chowing down furiously on gas — seen from...
