The Sun Sounds Like a Drum

The Sun isn’t silent—it’s constantly vibrating like a giant drum, just at frequencies too low for human ears. Turbulent gas churning beneath the surface generates sound waves that make the Sun “ring,” with patches of its surface moving up and down about every five minutes. By studying these vibrations, astronomers can map the Sun’s inner layers, just like geologists use seismic waves to study Earth’s core. So, while the Sun might look like a smooth, glowing sphere, it’s actually pulsing with a deep, cosmic hum.
