The earliest galaxies in the universe earned the nickname "monster galaxies" for good reason, they formed stars at rates hundreds of times faster than the Milky Way, growing rapidly after the dawn of time. Astronomers using ALMA and the James Webb Space Telescope have now revealed that three such monsters each achieved their extraordinary growth through completely different mechanisms. By comparing where stars are forming today with where they formed in the past, researchers discovered that galaxy collisions, internal instability, and minor mergers can all trigger these growth spurts, fundamentally changing our understanding of how the universe's most massive galaxies came to be.

Gravitational lensing is a powerful tool that brings impossibly distant galaxies into reach. The JWST uses galaxy clusters and their overpowering to magnify background galaxies that are otherwise beyond our observational capabilities. One cluster, named MACS J1149.5+2223, is 5 billion light-years away and holds at least 300 galaxies, probably many more. It's been chosen as the JWST's Picture Of The Month.
