The evolution of galaxies is the ultimate chicken-and-egg situation. Did the shapeless matter first gravitate together in larger structures, giving birth to stars and then to supermassive black holes? Or did the black holes form first and then trigger the creation of the first generation of ...
In this article, we'll find out how galaxies were discovered and what types exist, what they're made of, their internal structures, how they form and evolve, how they're distributed across the universe, and how active galaxies might emit so much energy. Contents What Is a Galaxy...

New findings are revealing how individual galaxies in galaxy clusters evolve over time, changing from chemically simple to complex and from spirals to smooth disks. Galaxies typically form in groups of a few dozen. Our own Milky Way is a member of a collection of more than 50 galaxies called...
"This discovery is going to become a benchmark system to study how sub-Neptunes, the most common type of planets outside of the solar system, form (and) evolve," Luque said. And it could also reveal "what are they made of and if they possess the right conditions to support the existe...
