Why Galaxies have Spiral Arms?! - The majestic spiral arms of galaxies are a source of wonder, but what exactly causes them to form? Is it the swirling dance of stars as they orbit the galactic center, or something more mysterious? Does the speed at which different parts of the galaxy rotate play a role? And why don't these arms simply wind up and disappear over time? | The Brain Maze

Welcome to the beautiful spiral galaxy NGC 2336, as seen by Hubble! Stretching across 200,000 light-years, this galaxy is tucked away in the northern constellation of Camelopardalis. NGC 2336 has spiral arms glittering with bright, blue, and young stars. The reddish center of the galaxy shows an area dominated by older stars. NGC 2336 resides about 100 million light-years away from Earth. Image credit: ESA/Hubble & NASA, V. Antoniou; Acknowledgment: Judy Schmidt Music credit: "Simple Pleasures"
