“Star cities” orbiting galaxies may reveal the mass of the gargantuan black hole hidden deep in the galaxy’s heart. The new relation could be more evidence for a large-scale black hole-galaxy link — or, it could mean one of the latest revolutions in astrophysics isn’t the full story.
With more than 100 billion galaxies in the observable universe, the exciting discoveries and unanswered questions are endless. Each one is unique, from ellipticals that have quenched their star formation to the vast and breathtakingly beautiful spiral galaxies imaged in so many galaxy pictures. We will update you on the latest from our neighbors, the Large and Small Magellanic Clouds, as well as the most distant stellar metropolises to form. Astronomers use instruments like the Hubble Space Telescope and the ALMA radio array in Chile to peer deep into the history of the universe, mapping star formation in young ‘uns residing in the early universe. In these news stories, you’ll find out what we’re learning about how galaxies form, evolve, and shape the beloved universe we call home.
